I was trying out the shiny new build system. Problem: configure is not executable - must run bash ./configure It's traditional for configure scripts to be executable.
Problem: Your life is hell if you have a non-compiler "cl" command on your PATH, even on Linux. checking for cl... /usr/bin/cl configure: Resolving CC (as /usr/bin/cl) failed, using /usr/bin/cl directly. with subsequent failure to compile. Even if you specify the compiler explicitly, it doesn't help: CC=/usr/bin/gcc CXX=/usr/bin/g++ bash ./configure Of course, one can work around this by creating a "tools dir", but excising the unloved cl from the configure script is tempting and effective.
