Since no Fedora 12 binary exists for the latest version of wine-1.1.42 I will compile from source. There are a lot development packages necessary for the compilation. Wine has a shell script for most distros, but unfortunately it does not support Fedora 12. I installed the packages manually using yum, then compiled. 30 mins later... $ echo '/usr/local/lib' >/etc/ld.so.conf.d/usr-local.conf $ /sbin/ldconfig Executing steam first, then launching CS:S from within steam. This time there is no output to the console indicating the mesa errors, but the game crashed the same way, with Steam staying on.
