Ninja not found by CMake


I'm trying to build some code I got from GitHub using CMake, but keep getting the followings errors:

CMake Error: CMake was unable to find a build program corresponding to "Ninja".  CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.
CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.
Missing variable is:
CMAKE_C_COMPILER_ENV_VAR
CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.
Missing variable is:
CMAKE_C_COMPILER
CMake Error: Could not find cmake module file:/golang/project/src/github.com/devsisters/goquic/libquic/build/debug/CMakeFiles/2.8.11/CMakeCCompiler.cmake
CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.
Missing variable is:
CMAKE_CXX_COMPILER_ENV_VAR
CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.
Missing variable is:

CMake Error: Could not find cmake module file:/golang/project/src/github.com/devsisters/goquic/libquic/build/debug/CMakeFiles/2.8.11/CMakeCXXCompiler.cmake
-- Configuring incomplete, errors occurred!

How do I set these variables correctly?

I used a ./build_libs.sh file that came with the GitHub code to build this.


Solution

  • The script you are executing uses the CMake Ninja generator. For that to work you need Ninja on the path. On most Linux distributions you can install it from a package.

    Ubuntu: ninja-build

    openSUSE: ninja

    If you can't find it for your distribution, you have to download it and add its location to the path environment variable.
