问题
I've build the Google Test with CMake on Mac OS X and get two shared libraries: libgtest.dylib and libgtest_main.dylib. And now I need install both them. I know there are some default search directories on Linux, such as /usr/lib, /usr/local/lib, etc.. But I am unfamiliar with Mac OS X and don't know where to place those libraries.
In Mac OS X Directory Structure, I find there are three directories of libraries: ~/Library, /Library and /usr/lib. And I've tried to place gtest libraries into these directories respectively and found out only /usr/lib works.
What I want to know is wether there are some rules about the default search directories on Mac OS X just like on Linux and Windows.
回答1:
Take a look at the default values for environment variables used by the dyld linker:
DYLD_FALLBACK_LIBRARY_PATH
...
By default, it is set to $(HOME)/lib:/usr/local/lib:/lib:/usr/lib
This article about "Deploying an Application on Mac OS X" and other article about "Mac OS X installers" may also help.
