macports, cmake/make and 'dyld: Library not loaded'

问题

I recently upgraded a library I use in a project of mine (glfw-devel) with macports and now my executable is dynamically link with lib/libglfw.3.dylib instead of opt/local/lib/libglfw.3.dylib which is the actual location of the lib so I get a dyld: Library not loaded error.

I know how to fix this with install-names or with a simple copy. What I cannot understand, however, is why this happens suddenly after a simple upgrade. I haven't changed anything in my CMakeLists.txt (the most relevant part is below) and all the other libraries I use have correct paths. Note that there is no place in the file where I refer to lib/.

Could it be a macports related issue? How can I make sure that my future binaries will be compiled with the proper paths?

回答1:

I encountered the same problem. And It took me hours to figure it out. It turned out that this problem is glfw version concerned. glfw version 3.1 is ok. Try it.

Or the bug had been posted in Macports buglist: glfw @3.2: install_name is not set properly
