Non ubuntu linux build

hi guys, not sure if it's the right place to ask. trying to compile swift on non ubuntu linux. as per README I cloned all the repos and started utils/build-script --release-debuginfo command. The error message I get makes me think that compiled clang unable to find gcc libs. any tips?

CMake Error at /usr/share/cmake/Modules/CMakeTestCCompiler.cmake:52 (message):
  The C compiler


  is not able to compile a simple test program.

  It fails with the following output:

What flavor of Linux are you using?

I've been building Swift with good results for Fedora. Check out this repo for the dependencies we've figured out: Hopefully that will point you in the right direction; if you get stuck reply back and I'll help in any way I can.

Thank you for your link. I'm on ALTLinux and have installed almost the same you have. Applied distro specific patches helped me to get working clang at least. Building swift...
