Summary0009997: .def files are not passed to the mingw linker
DescriptionThe .def files set in the source files for a shared library is correctly passed to the msvc linker through /DEF:..., but they are trimmed off when using the mingw ld linker.
The mingw ld linker follows the rules specified in .def files passed as source inputs.
Steps To Reproduce
Additional InformationThere is a workaround:
using, under IF(MINGW), LINKER_FLAGS of the style "-Wl,myfile.def" in order to get the .def file included.
TagsNo tags attached.

This was mostly addressed by the fixes for issue 0009613:

   http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=024d05ad [^]
   http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=0db2c850 [^]

The only thing that is missing is the value of CMAKE_LINK_DEF_FILE_FLAG in the platform files for the GNU toolchain on Windows. I've added the setting and enabled the test for this toolchain:

  http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=6a61a8a5 [^]

One can work around the problem for any CMake 2.8.[01234] with this code:

  # This platform information is missing in CMake <= 2.8.4.
  if(NOT CMAKE_LINK_DEF_FILE_FLAG AND "${CMAKE_C_COMPILER_ID}" STREQUAL "GNU")
    set(CMAKE_LINK_DEF_FILE_FLAG "-Wl,")
  endif()
