CMake fails on windows

[stefan-nu]

Hello,

I try to crosscompile NE10 on windows 7 64Bit.

CMake is configured to use linaro GCC crosscompiler arm-linux-gnueabihf.

When running CMake the linker fails with error message
arm-linux-gnueabihf/bin/ld.exe: unrecognized option '--out-implib'

Would somebody please point out how to correctly configure the cmake file to build on windows.

thank you very much.
Stefan

I think I found the solution:

in the CMake configuration file "GNUlinux_config.cmake" should be defined the target plattform as

set(CMAKE_SYSTEM_NAME Linux)

Then run cmake and specify the Generator with -G"MinGW Makefiles". This assumes that MinGW ist being used.

The complete command line ist

C:\...\NE10\build cmake -G"MinGW Makefiles" -DCMAKE_TOOLCHAIN_FILE=../GNUlinux_config.cmake ..
C:\...\Ne10\build make
