Hi Leonid,

You need to initialise CMake with the arm toolchains otherwise it will try and use your host toolchains by default.

CMake will print out the toolchain it uses when you initialise it:

../init-build.sh -DSIMULATION=ON -DPLATFORM=sabre -DAARCH32=ON -- The C compiler identification is GNU 7.3.0 -- The CXX compiler identification is GNU 7.3.0 -- Check for working C compiler: /usr/lib/ccache/arm-linux-gnueabi-gcc -- Check for working C compiler: /usr/lib/ccache/arm-linux-gnueabi-gcc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Detecting C compile features -- Detecting C compile features - done -- Check for working CXX compiler: /usr/lib/ccache/arm-linux-gnueabi-g++ -- Check for working CXX compiler: /usr/lib/ccache/arm-linux-gnueabi-g++ -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Detecting CXX compile features -- Detecting CXX compile features - done -- The ASM compiler identification is GNU -- Found assembler: /usr/lib/ccache/arm-linux-gnueabi-gcc -- Performing test HARD_FLOAT with flags -mfloat-abi=hard -- Test HARD_FLOAT FAILED -- Performing test SOFTFP_FLOAT with flags -mfloat-abi=softfp -- Test SOFTFP_FLOAT PASSED -- Configuring done

Hello,

I have tried to build sel4test following ‘running SEL4’ instruction.

It was successful for x86 platform, but when I try to build it for ‘zyncmp’ I’ve got an error:

gcc: error: unrecognized command line option ‘-marm’; did you mean ‘-mabm’? gcc: error: unrecognized command line option ‘-mfloat-abi=soft’

Thank you, Leonid
