can't compile my old projects (with gcc)

I have a broken C Compiler when I use CLion with yocto SDK, but it works fine on eclipse Oxygen. This is the error in the compiler:

    CMake Error at /home/developer/yocto_SDK2/toolchain2/sysroots/x86_64-pokysdk-linux/usr/share/cmake-3.7/Modules/CMakeTestCCompiler.cmake:51 (message):

      is not able to compile a simple test program.

And this is the log error:

I have also configured the paths manually, and it was fine. [![enter image description here][1]][1] enter image description here

Does anyone know how to resolve this problem for the gcc compiler ?

Solution

  • So after researching, trying and failing all the possible options, I found my answer which is the following: Apparently Clion can't detect the Compilers unless I source and cmake before launching Clion, so it could redirect the Compilers to Yocto compilers rather than detecting the host Compilers. So, I created the following Bash script which launches the mentioned commands.

    Sourcing setup_sdk as follows:

    #!/bin/bash

# define root paths
export SDK_TC_ROOT=~/yocto_sdk/toolchain
# source yocto sdk stuff
source ${SDK_TC_ROOT}/environment-setup-cortexa9hf-neon-poky-linux-gnueabi

    Then, I ran the following bash code to make sure that the setup runs correctly before launching Clion

    #!/bin/bash

PATH_TO_Clion=~/clion/bin
# setup env
source setup_sdk
cmake ./
# start Clion with all variables
$PATH_TO_Clion/clion.sh

    Then Clion auto-detected the Compilers correctly without defining them manually which resulted to the mentioned C Compiler Issue.

    It is worth to mention that Clion somehow doesn't accept the - parameter when defining Cmake Options in CMAKE_TOOLCHAIN_FILE=. As it compiled and build correctly for me. enter image description here
