Cygwin/ARM cross-compile cmake not able to compile a simple test program

asked 2016-01-17 21:19:31 -0500

I've been struggling with this all day. Under cygwin I get the result shown below. I tried a DOS command line approach as well with the same result. As near as I can tell, the scratch directories and their contents (cmTC_f7cac.dir in the example below) never get created, so when the compiler is called it complains that there is nothing to compile (fatal error: no input files).

Any help in getting past this would be greatly appreciated.


$ cmake -DCMAKE_C_COMPILER="/cygdrive/c/Program Files (x86)/Linaro/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10/bin/arm-linux-gnueabihf-gcc.exe" -DCMAKE_CXX_COMPILER="/cygdrive/c/Program Files (x86)/Linaro/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10/bin/arm-linux-gnueabihf-g++.exe" -DCMAKE_AR="/cygdrive/c/Program Files (x86)/Linaro/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10/bin/arm-linux-gnueabihf-ar.exe" -DCMAKE_TOOLCHAIN_FILE=/cygdrive/c/lib/opencv/sources/platforms/linux/arm-gnueabi.toolchain.cmake /cygdrive/c/lib/opencv/sources -- The CXX compiler identification is GNU 4.8.2 -- The C compiler identification is GNU 4.8.2 -- Check for working CXX compiler: /cygdrive/c/Program Files (x86)/Linaro/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10/bin/arm-linux-gnueabihf-g++.exe -- Check for working CXX compiler: /cygdrive/c/Program Files (x86)/Linaro/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10/bin/arm-linux-gnueabihf-g++.exe -- broken CMake Error at /usr/share/cmake-3.3.2/Modules/CMakeTestCXXCompiler.cmake:54 (message): The C++ compiler "/cygdrive/c/Program Files (x86)/Linaro/gcc-linaro-arm-linux-gnueabihf-4.8-2013.10/bin/arm-linux-gnueabihf-g++.exe" is not able to compile a simple test program.

It fails with the following output:
