I am now using Gentoo X64 instead of Ubuntu. I have cloned the latest wine-git and compiled it according to these instructions. All the emulation libraries are already installed http://wiki.winehq.org/WineOn64bit#head-7f9ba30a115acb6bc6feef3ee48cd06e91d44519 (I ran the configure script first, make depend, the make line in the howto and then su -c "make install") With my former Ubuntu installation I had a wine "repository" where all the prefixes of the games I was testing were located (eg. /wine/warcraft3/). I kept the hard drive where it was located as it is and mounted it in Gentoo the same way it was in Ubuntu. So far I have attempted to run winecfg and load these games : WoW, Warcraft 3, Diablo 2, Drømmefall: Den Lengste Reisen. I get the exact same output for each of them whether for winecfg or when I load the game. Winecfg appears after about 15-20 seconds, but the games do not load. ALSA lib seq_hw.c:457:(snd_seq_hw_open) open /dev/snd/seq failed: No such file or directory fixme:advapi:SetSecurityInfo stub X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 156 (GLX) Minor opcode of failed request: 3 (X_GLXCreateContext) Value in failed request: 0x21 Serial number of failed request: 25629 Current serial number in output stream: 25630 I would like to know if you guys think this is a Wine issue or a Gentoo issue; hence I could redirect it to the appropriate forum if necessary. If this is a Wine issue, do you have a workaround suggestion? Thanks!
