| Summary | 0016078: CMake on Cygwin with clang not creating expected dll.a | ||||||||
| Description | I'm building a shared library and an application using that lib on Cygwin. With GCC CMake creates a .dll.a to use when linking. Switching to clang I get [ 34%] Built target xyz_shared make[2]: *** No rule to make target 'src/libxyz_shared.dll.a', needed by 'xyz.exe'. Stop. | ||||||||
| Steps To Reproduce | On Cygwin, use the attached CMakeLists.txt and see it produce 'cygxyz_shared.dll' and 'libxyz_shared.dll.a'. Clear the build directory and do $ CC=clang cmake ..; make and it will not create 'libxyz_shared.dll.a'. | ||||||||
| Additional Information | As described in this Stackoverflow question (http://stackoverflow.com/questions/36294199 [^]) the culprit seems to be the lack of the flags '-Wl,--enable-auto-import' when using clang. | ||||||||

I think this was fixed in post-3.5 development by this commit: Cygwin: Add support for Clang compiler https://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=517cef8c [^] |
