Wine is an Open Source implementation of the Windows API on top of X and Unix. This script includes the capability to enable/disable OpenGL acceleration: read the script for more information. If you are building this on Slamd64, execute the build script as follows: DISTRO=slamd64 ARCH=x86_64 ./wine.SlackBuild If you build on a multicore system, add JOBS={#} to enable parallel compilation, as in: JOBS=4 ./wine.SlackBuild which starts up to 4 build jobs simultaneously. While it's not strictly required, the fontforge package is strongly recommended to be installed when building wine.
