ROOT Version: root_v6.18.04
Platform: Scientific Linux 6.10
Compiler: GCC 9.3.0
CMake: CMake version 3.17.0
I’m trying to build ROOT following the README.md:
git clone https://github.com/root-project/root.git mkdir build cd build cmake ../root <- Here occurs an error! make -j8 source bin/thisroot.sh root
When I executed
cmake ../root, I got the error message below:
CMake Error at interpreter/llvm/src/cmake/modules/CheckAtomic.cmake:49 (message): Host compiler must support std::atomic! Call Stack (most recent call first): interpreter/llvm/src/cmake/config-ix.cmake:330 (include) interpreter/llvm/src/CMakeLists.txt:585 (include)
As yum provides outdated GCC and CMake, I built them myself from the source code.
I would appreciate if anyone helped me resolve this problem.
