     36== 3. Did you install the compiler toolchain? Good. ==
     37
     38If you did not, it won't work! Don't even try to pester us about that. It won't work. Because it won't. It can't.

     40Why can't it work?
     41 * Tool versions: We only test HelenOS on the one single version of GCC, binutils, etc. We don't have the resources to test other versions. Other versions have bugs (or lack required features). It won't compile.
     42 * Different ABIs: Each OS has a different ABI and different set of compiler settings. If you build binaries with your native compiler, they will run fine in your OS, but certainly not in HelenOS!
     43 * {{{-Werror}}}: Developer builds use -Werror and each compiler version produces different warnings. Thus, you will get warnings and these get turned into erros.
     44
     45== 4. Configure and build ==

    4556'''Note:''' Do not select a different compiler! If you use ''gcc_native'' instead of ''gcc_cross'', it won't work, so please don't ask in the mailing list! Building HelenOS with a native compiler is '''not supported'''!
