CLion: Can not Use non-EABI compiler
I try evaluate Clion for Embedded ARM CPU. I test with clion 2016.3
I read :
https://dev.widemeadows.de/2015/02/12/forcing-arm-eabi-gcc-onto-clion-eap-on-windows/
https://blog.jetbrains.com/clion/2016/06/clion-for-embedded-development/
i must use minGW or cygwin. i choose minGW-64 5.4
after it i override mingw & use arm-none-EABI compiler in then
In CLion’s Build, Execution, Deployment > CMake settings we then set the CMake Generation options with
|
|
-DTOOLCHAIN_DIR:PATH=c:/path/to/arm-non-eabi/
-DCMAKE_TOOLCHAIN_FILE=toolchain.cmake
seems make not use my non-eabi compiler & use mingw compiler !
Cannot get compiler information for configuration Debug: Compiler exited with error code 1: C:\mingw64-5.4\bin\gcc.exe

Are you able to run the compiler successfully from the command line (outside of CLion, without CMake)?
