Well... as many people requested it, I'll post a SHORT tutorial on how build wine from sources and apply the 2 patches needed to run Autocad 2005 (and to some extents, 2008). First of all... Read The Fine Manual. WineHQ is full of suggestions on how to build wine. Second, please don't ask me how to build on 64 bit ubuntu or other architectures, it can become complicated and I've got no time to test it. BTW, it's all somewhere in winehq, so again RTFM :-) So, just for ubuntu, and ubuntu32 in detail. ALL FOLLOWING COMMANDS IN A TERMINAL ! 1) REMOVE default ubuntu wine... you'll have problems if you don't. Code: sudo apt-get remove wine 2) install GIT : Code: sudo apt-get install git-core 3) fetch wine sources : (http://www.winehq.org/site/git) Code: git clone git://source.winehq.org/git/wine.git wine-git you'll get a subfolder called wine-git with all source code. 4) Install dependencies for wine: (https://help.ubuntu.com/community/BuildingWineFromSource) Code: sudo apt-get build-dep wine sudo apt-get install fakeroot 5) go inside wine-git folder, configure/make/make install: Code: cd wine-git ./configure --prefix=/usr make make install So far, you have built latest wine from sources and installed it, no patch On next post, the rest.
