Since an installation via .exe does not work I’m trying to build ROOT from source now:
C:\ROOT\install_dir> cmake -DCMAKE_INSTALL_PREFIX=C:\ROOT\install_dir C:\Users\User\Downloads\root_v6.26.02.source\root-6.26.02
– Building for: NMake Makefiles
CMake Deprecation Warning at CMakeLists.txt:12 (cmake_policy):
The OLD behavior for policy CMP0091 will be removed from a future version
The cmake-policies(7) manual explains that the OLD behaviors of all
policies are deprecated and that a policy should be set to OLD only under
specific short-term circumstances. Projects should be ported to the NEW
behavior and not rely on setting a policy to OLD.
CMake Error at CMakeLists.txt:30 (project):
The system cannot find the file specified
CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
– Configuring incomplete, errors occurred!
See also “C:/ROOT/install_dir/CMakeFiles/CMakeOutput.log”.
I followed exactly Building ROOT from source - ROOT so I don’t know what’s wrong here. It seems further parameters need to be passed to the entered command but which and why isn’t it given in the instruction?
