Using Qt Creator, I have built the release version of my application on /Documents/QtProjects/build-renamer-Desktop_Qt_5_1_0_clang_64bit-Release.So the first thing I did was run otool on my application:
I thought that running otool -L renamer.app/Contents/MacOS/renamer would change the output to the new Qt paths, but it is still the same. I thought I followed all the steps, but it doesn't work. Did I miss a step or do something wrong? I am able to successfully deploy my program on Windows without a problem, but I'm having trouble on the Mac. How can I make it so that running otool will display the newly set path for finding the QtCore, QtGui and QtWidgets framework from within my renamer.app bundle?
Renamer 5.1.0 MAC OS X
I also tried to use macdeployqt to deploy my app, but my app doesn't work when I rename/remove the Qt library installed under /Qt5.1.0/5.1.0/clang_64. I tried the commands sudo macdeployqt renamer.app under my project folder after adding /bin to my PATH. The macdeployqt runs fine, but when I rename/remove Qt, my application no longer runs. I also ran otool after running macdeployqt, but the output hasn't changed. I think macdeployqt copies the necessary Qt libraries to the app bundle, but does not correctly change where to look for the qt libraries.

With Renamer, you can save hours of tedious typing at the stroke of a button.
Add 5.2.1 classifiers built with additional data and tuning. These are approved for U.S.F.W.S. Northern long-eared bat surveys, but they are NOT approved for Indiana bat surveys. This version also includes older 5.1.0 classifiers which are approved for both Northern long-eared and Indiana bat surveys using the balanced setting.Fix bug related to extracting negative values of latitude and longitude coordinates for output to .csv files and database records.
Keep your collection of custom filters through a minor updates to patch Gramps (e.g., from version 5.1.0 to 5.1.2) by manually copying your custom_filter.xml from Gramps User Directory to the corresponding directory in new gramps_version_number. Even minor upgrades with feature changes (e.g., from a 5.0.x to a 5.1.x version) may include XML format changes since the recent innovation of addon rules are causing rapid evolution in Filters. So porting filters in this manner requires verification that the XML definitions haven't changed. Also, Addon rules may have to be installed in the new upgrade before copied custom filters will work safely.
Improved upgrade processThis update improves the reliability of the upgrade process. If you already upgraded to version 11.5.1.0-CN1, there is no need to upgrade to version 11.5.1.0-CN2, because your upgrade was already successful and there is no other benefit.
Version changeDb2 Warehouse changed its versioning to reflect the level of the Db2 engine that it uses. Db2 Warehouse 11.5.1.0 uses the Db2 11.5 engine, which was released in July 2019, and has since been updated with the following additional features and fixes:
LaTeX: removal of some internal TeX \dimen registers (not previouslypublicly documented) as per 5.1.0 code comments in sphinx.sty:\sphinxverbatimsep, \sphinxverbatimborder, \sphinxshadowsep,\sphinxshadowsize, and \sphinxshadowrule. (refs: #11105)
To upgrade to Cumulus Linux 5.1.0 from Cumulus Linux 4.x or 3.x, you must install a disk image of the new release using ONIE. You cannot upgrade packages with the apt-get upgrade command.
Upgrading an MLAG pair requires additional steps. If you are using MLAG to dual connect two Cumulus Linux switches in your environment, follow the steps in Upgrade Switches in an MLAG Pair below to ensure a smooth upgrade.
Install a Cumulus Linux image if you are performing a rolling upgrade in a production environment and if are using up-to-date and comprehensive automation scripts. This upgrade method enables you to choose the exact release to which you want to upgrade and is the only method available to upgrade your switch to a new release train (for example, from 4.4.3 to 5.1.0).

Xnu-qemu-arm64 is based on 4.2.0. QEMU 4.2.0 has very limited support of ARMv8.3 and no support for the LDAPR instruction. The immediate task ahead was to move all the xnu-related source files over to a freshly downloaded source of QEMU 5.1.0. Below is a Git diff showing the files added to the official QEMU 5.1.0 source from xnu-qemu-arm64:
Due to changes in the source from QEMU 4.2.0 to 5.1.0, memory_region_allocate_system_memory had to be changed to memory_region_init_ram. It takes the same arguments in the same order plus one extra (&error_fatal). The full Git diff file can be downloaded below:
PowerGREP can now search through disk images using the NTFS (Windows), HFS+ (OS X), ext2, ext3, and ext4 (Linux) file systems. You can enable or disable these as part of the archive format configuration. If you upgrade from PowerGREP 5.0.x to 5.1.0 then these new formats are automatically added to the predefined archive format configurations. If you load an action or file selection saved with a previous version of PowerGREP, then the new formats are not automatically added. This ensures that a saved action or file selection continues to work exactly the way it did when you saved it. If the saved file selection uses a archive format configuration as predefined in 5.0.x then this is indicated with a number such as (2) in the File Selector to indicate that it uses different settings from the new predefined configuration in 5.1.0.
Top JNA Home API w/FRAMES Java Native Access (JNA)JNA provides simplified access to native library methods without requiring anyadditional JNI or native code.Table of ContentsLoading JNALibrary MappingFunction MappingType Mapping Primitive Types Pointers Strings Wide (UNICODE) Strings Primitive Arrays Buffers/Memory Blocks Callbacks/Function Pointers Variable Argument Lists (Varargs) Structures Unions Java Objects Last Error Invocation MappingLibrary Global DataVM Crash ProtectionPerformanceTopLoading JNAJNA includes a small, platform-specific shared library which enables allnative access. When the Native class is first accessed,JNA will first attempt to load this library from the directories specifiedin jna.boot.library.path. If that fails and jna.nosys=falseis set, it will fall back to loading from the system library paths. Finally itwill attempt to extract the stub library from from the JNA jar file, and load it.The jna.boot.library.path property is mainly to supportjna.jar being included in -Xbootclasspath, wherejava.library.path and LD_LIBRARY_PATH are ignored. It is alsouseful for designating a version of the library to use in preference to anywhich may already be installed on the system.Loading from the system may be enabled by jna.nosys=false,and unpacking from the jar file may be disabled byjna.nounpack=true.The library name used to search for JNA's native library may be alteredby setting jna.boot.library.name, which defaults to"jnidispatch". It may be useful to set this value if your systemrequires unique names for shared libraries (rather than unique paths),or if your system must store different versions of the JNA sharedlibrary (e.g. for different architectures) in the same directory.TopLibrary MappingWhen you've determined which shared library holds the methods to which youneed access, create a class corresponding to that library. Forexample, a mapping for the C library itself would look like one of thefollowing: // Alternative 1: interface-mapped class, dynamically load the C librarypublic interface CLibrary extends Library CLibrary INSTANCE = (CLibrary)Native.load("c", CLibrary.class);// Alternative 2: direct-mapped class (uses a concrete class rather than an// interface, with a slight variation in method// declarations). public class CLibrary static Native.register("c"); The String passed to theNative.load(String,Class)(or NativeLibrary.getInstance(String)) methodis the undecorated name of the shared library file. Here are some examples oflibrary name mappings. table.styled border-collapse:collapse; background-color:#EAEAEA; td padding-left: 10px; padding-right: 10px; blockquote background-color:#EAEAEA; OSLibrary NameStringWindowsuser32.dlluser32LinuxlibX11.soX11Mac OS Xlibm.dylibmMac OS X Framework/System/Library/Frameworks/Carbon.framework/CarbonCarbonAny PlatformnullAny given native library with a unique filesystem path is represented by a single instance of NativeLibrary and obtained via NativeLibrary.getInstance(String). The native library will be unloaded when no longer referenced by any Java code.If the library name is null, your mappings will apply to thecurrent process instead of a separately loaded library. This may help avoidconflicts if there are several incompatible versions of a library available.The search path for loaded native libraries may be modified bysetting jna.library.path and a few other properties. You mayalso bundle native libraries in a jar file and have JNA automatically extractthem for loading. See NativeLibrary for details. Table of ContentsFunction MappingFunction names are mapped directly from their Java interface name to thesymbol exported by the native library. For instance, the function to convertan ASCII string into an integer would look like this:public interface CLibrary extends Library int atol(String s);Alternatively, you can map directly to a declared native method (with some restrictions):public class CLibrary public static native int atol(String s);If you prefer to rename the Java methods to conform to Java coding conventions, then you can provide an entry (Library.OPTION_FUNCTION_MAPPER/FunctionMapper) in the options Map passed to Native.load() which maps the Java names to the native names. While this keeps your Java code a little cleaner, the additional mapping of names may make it a little less obvious the native functions being called.An instance of the Function class is obtained through the NativeLibrary instance corresponding to the containing native library. This Function instance handles argument marshalling and delegation to the native function. Table of ContentsMarshalling/Unmarshalling (Java/Native Type Conversions)Java types must be chosen to match native types of the same size. Following are the types supported by the JNA library.C TypeNative RepresentationJava Typechar8-bit integerbytewchar_tplatform-dependentcharshort16-bit integershortint32-bit integerintintboolean flagbooleanenumenumeration typeint (usually)long long, __int6464-bit integerlongfloat32-bit floating pointfloatdouble64-bit floating pointdoublepointer (e.g. void*)platform-dependent (32- or 64-bit pointer to memory)BufferPointerpointer (e.g. void*),array32- or 64-bit pointer to memory (argument/return)contiguous memory (struct member)[] (array of primitive type)In addition to the above types, which are supported at the native layer, the JNA Java library automatically handles the following types. All but NativeMapped and NativeLong are converted to Pointer before being passed to the native layer.longplatform-dependent (32- or 64-bit integer)NativeLongconst char*NUL-terminated array (native encoding or jna.encoding)Stringconst wchar_t*NUL-terminated array (unicode)WStringchar**NULL-terminated array of C stringsString[]wchar_t**NULL-terminated array of wide C stringsWString[]void**NULL-terminated array of pointersPointer[]struct*structpointer to struct (argument or return) (or explicitly)struct by value (member of struct) (or explicitly)Structureunionsame as StructureUnionstruct[]array of structs, contiguous in memoryStructure[]void (*FP)()function pointer (Java or native)Callbackpointer ( *)same as PointerPointerTypeotherinteger typeIntegerTypeothercustom mapping, depends on definitionNativeMappedNOTESUnsigned values may be passed by assigning the corresponding two's-complement representation to the signed type of the same size. Java arrays of primitive type may be wrapped by Buffer in order to access a subset of the array (changing the effective size and/or offest).Java arrays of primitive type and non-direct Buffers are only valid for use within the scope of a single call. If the native code keeps a reference to the memory, use Memory or direct ByteBuffers instead.Primitive arrays and structures as members of a structure are overlaid on the parent structure memory. Bitfields must be manually packed into an integer type. All other types must eventually be converted to one of the types in the this table. Methods with arguments or return values of types other than these must either use types deriving from NativeMapped or supply type conversion information for the unsupported types. Type mapping behavior may be customized by providing a TypeMapper for the Library.OPTION_TYPE_MAPPER option when initializing a library interface. See W32APITypeMapper for an example which provides custom conversion of boolean and String types. You are free to use whatever types are convenient in your defined interfaces, but all custom types must provide a mapping to one of the basic or derived types listed above.Type mapping may also be customized on a per-class basis for user-defined types by making the user-defined type implement the NativeMapped interface. Structure and Union are not converted to Pointer when passed by value.Primitive ArraysJava primitive arrays may be used wherever a native primitive array is used. Any changes made by the native code to an array during a function call will be reflected in the Java array. If the native code will use the array outside of the function call where the array is provided, Memory or Buffer should be used instead (see Buffers).To map a native multi-dimensional array, use a single-dimensional Java array with a number of elements equivalent to the full native array, e.g.// Original C code#define DIM0 2#define DIM1 3int array[DIM0][DIM1];int i,j;for (i=0;i Device dev = new Device();// As an array of StructureStructure[] structs = dev.toArray(size);// As an array of DeviceDevice[] devices = (Device[])dev.toArray(size);Returning an Array of structDeclare the method as returning a Structure of theappropriate type, then invoke Structure.toArray(int) toconvert to an array of initialized structures of the appropriate size. Notethat your Structure class must have a no-args constructor,and you are responsible for freeing the returned memory if applicable inwhatever way is appropriate for the called function.// Original C codestruct Display* get_displays(int* pcount);void free_displays(struct Display* displays);// Equivalent JNA mappingDisplay get_displays(IntByReference pcount);void free_displays(Display[] displays);...IntByReference pcount = new IntByReference();Display d = lib.get_displays(pcount);Display[] displays = (Display[])d.toArray(pcount.getValue());...lib.free_displays(displays);Nested Structure DefinitionsNested structures are treated as consecutive memory (as opposed to pointers tostructures). For example:// Original C codetypedef struct _Point int x, y; Point;typedef struct _Line Point start; Point end; Line;// Equivalent JNA mappingclass Point extends Structure public int x, y;class Line extends Structure public Point start; public Point end;Explicit initialization of nested structures is not required; the objects willbe created as needed and properly mapped to the parent structure's memory.If you need a pointer to a structure within your structure, you can use theStructure.ByReference tagging interface to indicate thefield should be treated as a pointer instead of inlining the full structure.// Original C codetypedef struct _Line2 Point* p1; Point* p2; Line2;// Equivalent JNA mappingclass Point extends Structure public static class ByReference extends Point implements Structure.ByReference public int x, y;class Line2 extends Structure public Point.ByReference p1; public Point.ByReference p2;The more general case is just a pointer to memory. This allows you to definethe field without necessarily defining the inner structure itself, similar todeclaring a struct without defining it in C:// Original C codetypedef struct _Line2 Point* p1; Point* p2; Line2;// Equivalent JNA mappingclass Line2 extends Structure public Pointer p1; public Pointer p2;Line2 line2;Point p1, p2;...line2.p1 = p1.getPointer();line2.p2 = p2.getPointer();Nested arraysStructures with nested arrays require an explicit constructor to ensure thestructure size is properly calculated.typedef struct _Buffer char buf1[32]; char buf2[1024]; Buffer;class Buffer extends Structure public byte[] buf1 = new byte[32]; public byte[] buf2 = new byte[1024];Calculation of the native size of the structure is deferred until thestructure is actually used.Variable-sized structuresStructures with variable size, or with primitive array elements, for example:// Original C codetypedef struct _Header int flags; int buf_length; char buffer[1]; Header;require a constructor which establishes the required size for the structureand initializes things appropriately. For example:// Equivalent JNA mappingclass Header extends Structure public int flags; public int buf_length; public byte[] buffer; public Header(int bufferSize) buffer = new byte[bufferSize]; buf_length = buffer.length; allocateMemory(); Volatile fieldsNormally, JNA will write the entire contents of a Structure priorto a function call and read back from native memory after the function call.Sometimes a structure field is not intended for client use, gets modifiedasynchronously by hardware, or otherwise is effectively read-only.If you expect any fields of the structure to be modified by any agent outsideyour Java program, you should mark the field volatile. Thisprevents JNA from automatically updating the native memory from the Javavalue. You can still force an update of the native memory from the Java valueby calling Structure.writeField(String) for the field inquestion. class Data extends com.sun.jna.Structure public volatile int refCount; public int value;...Data data = new Data();In the above example, the field refCount will only be writtento native memory based on the Java value with a call todata.writeField("refCount"). To obtain the current state ofnative memory, call Structure.read() (to update the entirestructure) or data.readField("refCount") (to update just the refCount field). Read-only fieldsIf you want to absolutely prevent Java code from modifyinga Structure's contents, you may mark itsfields final. Structure reads can still overwrite the valuesbased on native memory contents, but no Java code will be able to modify anyof the fields.class ReadOnly extends com.sun.jna.Structure // Do not initialize the field here, or the compiler will inline the value! public final int refCount; // Initialize fields here, to ensure the values are not inlined refCount = -1; read(); // refCount might now have a different value ...ReadOnly ro = new ReadOnly();// Will not compile!ro.refCount = 0;Make certain you attend to the following:All final fields should be initialized in the constructor.If you call Structure.read() from anywhere but the constructor, keep in mind that the compiler and/or hotspot will be assuming field values will not change across that function call.UnionsUnions are a special type of Structure. Each declared field within the unionoverlays the same space in native memory. When writing a union to nativememory, you must specify which field is to be written by supplyingthe desired field's class to the Union.setType(java.lang.Class)method. On read, all non-pointer-based fields will be initialized from nativememory. Structure, String, and WString members will not beinitialized unless they are selected via Union.setType(java.lang.Class).Obtaining "last" errorIf a function sets the system error property(errno or GetLastError()), the error code will be thrown as a LastErrorException if you declare the exception in your JNA mapping. Alternatively, you can use Native.getLastError() to retrieve it. Throwing an exceptionis preferred since it has better performance.Arbitrary Java Object arguments/return valuesIn some cases, such as invoking native VM functions directly, it is necessaryto pass Java objects to the native methods. By default, JNA disallows usingany Java object that is not explicitly supported unless it derives fromNativeMapped, because it is generally unnecessary to usesuch objects and usually signals a programmer error. To avoid errors flaggingthe use of Java objects, use the library load option Library.OPTION_ALLOW_OBJECTS with Boolean.TRUE.Table of ContentsInvocation MappingSometimes native functions exist only as C preprocessor macros or as inline functions. If you need to do more than simply change the name of the invoked function (which can be handled via Function Mapping), an InvocationMapper allows you to arbitrarily reconfigure the function invocation, including changing the method name and reordering, adding, or removing arguments. See the InvocationMapper documentation for details.Table of ContentsLibrary Global DataThe method NativeLibrary.getGlobalVariableAddress(java.lang.String) may be used to obtain the address of global variables as a Pointer. Pointer methods may then be used to read or write the value as appropriate for the variable type.Table of ContentsVM Crash ProtectionIt is not uncommon when defining a new library and writing tests to encounter memory access errors which crash the VM. These are often caused by improper mappings or invalid arguments passed to the native library. To generate Java errors instead of crashing the VM, call Native.setProtected(true). Not all platforms support this protection; if not, the value of Native.isProtected() will remain false.NOTE: When protected mode is enabled, you should make use of the jsig library, if available (see Signal Chaining) to avoid interfering with the JVM's use of signals. In short, set the environment variable LD_PRELOAD (or LD_PRELOAD_64) to the path to libjsig.so in your JRE lib directory (usually $java.home/lib/$os.arch/libjsig.so) before launching your Java application. Table of ContentsPerformanceUse direct mapping of methodsUsing direct mapping of methods makes nativecalls more efficiently than does interface mapping. Direct mapping does notsupport varargs calls or arrays of Pointer, String, or WString as an argumentor return value. For optimium results, use only primitive arguments andreturn values; you'll have to convert to and from objects yourself explicitly.Avoid type mappingType mapping incurs additional overhead on each function call. You can avoidthis by ensuring that your arguments and/or return types are already primitivetypes.Pointer/Array/Buffer VariantsJava primitive arrays are generally slower to use than direct memory(Pointer, Memory, or ByReference) or NIO buffers, since the Java memory has tobe pinned and possibly copied across the native call, since the Java array is not necessarily contiguously allocated.Large StructuresStructures are normally written to native memory before and read back fromnative memory after a function call. With very large structures, there can bea performance hit using reflection to walk through all the fields. Structureauto-synch can be disabled by callingStructure.setAutoSynch(boolean) with a false parameter.It is then up to you to use Structure.readField(String)and Structure.writeField(String) or Structure.writeField(String,Object) to synch with just the fieldsof interest. Throw exceptions on last errorIn those methods where you are interested in the value of errno/GetLastError(),declare your method to throw LastErrorException.Skip navigation linksOverview
