Question

我在OS X上创建了一个Photoshop插件（基本上是一个Bundle / DyLib）。
我使用英特尔编译器并通过链接OpenMP（libiomp5）来使用OpenMP 当我使用静态链接时，它会崩溃Photoshop（仅在OS X上，在Windows上它可以工作）所以我尝试了动态链接。

主机Photoshop自己使用libiomp5.dylib，它在Framework文件夹中可用所以，在Xcode上我设置链接部分Runpath Search Paths到@executable_path/../Frameworks/但是当我尝试在Photoshop上加载它时它不会工作。
我还尝试将Runpath Search Paths设置为Intel Run Time Redistributable Libraries（其中包括根据MacDependency插件所需的所有DyLib，就像Photoshop的框架库一样）但它仍然赢得了＃39} ;加载Photoshop。

当我在插件上使用otool -L时，我得到：

/System/Library/Frameworks/Carbon.framework/Versions/A/Carbon (compatibility version 2.0.0, current version 157.0.0)
    libimf.dylib (compatibility version 0.0.0, current version 0.0.0)

当我在插件上尝试otool -l时，我确实看到了我在Xcode中插入的内容：

如果我将Runpath Search Paths设置为Intel Run Time Redistributable Libraries，我也会看到正确的路径，但结果是一样的。

有人可以帮助我吗？我不是很熟悉开发人员，所以一步一步会很棒。

对于了解@rpath的现代图书馆，您的解决方案是正确的。 OpenMP库支持@rpath启动编译器版本16.0更新2.在您的情况下，您的RPATH设置被系统忽略

您可以尝试使用photoshop中的openmp库进行链接吗？据我所知，他们为此做了一个解决方法，并将libiomp5.dylib中的install_name更新为“@executable_path /../ Frameworks / libiomp5.dylib”。因此，如果您链接到该库，“otool -l”输出中的openmp名称将更改为@executable_path /../ Frameworks / libiomp5.dylib

一些提示

如果photoshop更新通过install_name_tool安装名称

 $ otool -l ./a.out | grep omp
 name libiomp5.dylib (offset 24)
 # libiomp5.dylib was copied to the location with test 
 $ install_name_tool -id "@executable_path/../Frameworks/libiomp5.dylib" libiomp5.dylib
 $ LIBRARY_PATH=.:$LIBRARY_PATH icc -openmp test1.cpp 
 $ otool -l ./a.out | grep omp
 name @executable_path/../Frameworks/libiomp5.dylib (offset 24)

RPATH用法

install_name_tool -id "@executable_path/../Frameworks/libiomp5.dylib" libiomp5.dylib
$ LIBRARY_PATH=.:$LIBRARY_PATH icc -openmp test1.cpp -Wl,-rpath,.
$ ./a.out
dyld: Library not loaded: @executable_path/../Frameworks/libiomp5.dylib
  Referenced from: /nfs/inn/home/vpolin/mac/./a.out
  Reason: image not found
Trace/BPT trap: 5
$ install_name_tool -id "@rpath/libiomp5.dylib" libiomp5.dylib
$ LIBRARY_PATH=.:$LIBRARY_PATH icc -openmp test1.cpp -Wl,-rpath,.
$ otool -l ./a.out | grep omp
         name @rpath/libiomp5.dylib (offset 24)
$ ./a.out
