How to build CMake with particular C flags

I'm trying to build CMake with options that outlaws the variable-length array feature in C, to find out if CMake depend on this feature.

Note that I'm building CMake, not using CMake to build something else.

Solution

  • Seeking through the bootstrap script and found this:

      CC=*) CC=`cmake_arg "$1"` ;;
  CXX=*) CXX=`cmake_arg "$1"` ;;
  CFLAGS=*) CFLAGS=`cmake_arg "$1"` ;;
  CXXFLAGS=*) CXXFLAGS=`cmake_arg "$1"` ;;
  LDFLAGS=*) LDFLAGS=`cmake_arg "$1"` ;;

    Looks like invoking ./configure CFLAGS="-Werror=vla" will do.
