Get Error by run cmake

[k-al]

A friend of mine and I have tried to use EtherealEngine and we both (my friend on Windows/me on Linux) failed to run cmake. Did we get someting wrong or is the version we're using buggy?

It should run fine

Did you follow the build steps in the readme

Yes, when I executed the cmake I get this on the terminal:

-- The C compiler identification is GNU 5.4.0 -- The CXX compiler identification is unknown -- Check for working C compiler: /usr/bin/cc -- Check for working C compiler: /usr/bin/cc -- broken CMake Error at /usr/share/cmake-3.5/Modules/CMakeTestCCompiler.cmake:61 (message): The C compiler "/usr/bin/cc" is not able to compile a simple test program.

It fails with the following output:

CMake will not be able to correctly generate this project. Call Stack (most recent call first): CMakeLists.txt:3 (project)

CMake Error at CMakeLists.txt:3 (project): No CMAKE_CXX_COMPILER could be found.

Tell CMake where to find the compiler by setting either the environment variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path to the compiler, or to the compiler name if it is in the PATH.

well it says it right there... Tell CMake where to find the compiler by setting either the environment variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path to the compiler, or to the compiler name if it is in the PATH. try running it like this

cmake -DCMAKE_C_COMPILER=path_to_your_gcc -DCMAKE_CXX_COMPILER=path_to_your_g++ ..

where path_to_your_gcc and path_to_your_g++ is where your compiler is located. Do you even have any compiler installed on your system? You can also use the any IDE that supports CMake to run it like Qt Creator, Visual Studio, Visual Studio Code etc... or you can use the CMake GUI on windows.

Yes that was the problem. after moving the g++ in a $PATH directory it get an other result. Now it says: "Xrandr library not found" When I tried to install xrandr, apt says the x11-xserver-utils package replace it, but I have installed the x11-xserver-utils. Also whereis says that xrandr is accessible under /usr/bin/xrandr

after searching a bit in the error-logs I saw, the cmake found the x11-utils, but didn't got back an thread:
