I am running Fedora KDE Spin. I was trying to compile a program. I tried running cmake but I got the following error:
CMake Error: your CXX compiler: “CMAKE_CXX_COMPILER-NOTFOUND” was not found. Please set CMAKE_CXX_COMPILER to a valid compiler path or name.
I already had gcc and cpp packages installed but I was still getting the above error.
I later figured that the package gcc-c++ was not installed. I installed it via yum and the error was gone:
yum install gcc-c++
Hope this helps.
