Dear list
On Windows, MinGW (gcc 4.5.2), CMake 2.8.4.
I have a project building two executables. The first one builds correctly. On
the second one it appears to me as though CMake adds flags to link to the
standard MinGW libraries (mingw32, moldname, mingwex, ...) with an incorrect
.lib suffix. (See the output below) As far as I can tell this is totally
unnecessary since these flags are automatically added by the gfortran compiler.
So in the end I have -lmingw32.lib (presumably added by CMake, which fails) and
-lmingw32 (automatically added by gfortran, which correctly links libmingw32.a)
My CMakelists file for the target CE_SEMFEM is
-------------------------------------------------------------------------------------------------------
cmake_minimum_required (VERSION 2.8.4)
project (CE_SEMFEM Fortran)
set (CE_SRCS
src/CE_SEMFEM.f95
src/CE_config_module.f95
)
add_executable (CE_SEMFEM ${CE_SRCS})
target_link_libraries (CE_SEMFEM SEMFEM CE_FEMxml xmlparse)
-------------------------------------------------------------------------------------------------------
The libraries SEMFEM, CE_FEMxml and xmlparse are built elsewhere in the project.
Ideas how I can fix this? Any help is much appreciated.
