我有一个依赖于几个的 C++ 应用程序.dylib;其中,libprojPythonQt

我在单独的目录中预先构建了这些库。

2个(相关)问题:

  • 可执行文件找到 的完整路径libproj.dylib,尽管它不在路径中,不在 中DYLD_LIBRARY_PATH,不在 QtCreator 的配置中。如何 ?
  • 可执行文件找不到 PythonQt,尽管它的链接方式完全相同。我必须手动添加正确的路径DYLD_LIBRARY_PATH。为什么 ?

这可能与libproj有a.la和a.dylib有关,但PythonQt只有a .dylib;但我不确定,我不明白这种关系。

otool 的示例输出:

/Users/arnaud/Projects/myprojectname/external/proj-4.8.0/bin_mac64_gcc421_release/lib/libproj.0.dylib (compatibility version 8.0.0, current version 8.0.0)
    ( so it finds libproj correctly, even in another directory )

libPythonQt.1.dylib (compatibility version 1.0.0, current version 1.0.0)
    (... but not libPythonQt, which is in a similar directory )
