No, it forces certain linker flags in the generated Makefiles. If the flag allows the package to compile, keep it.
Seems to be working! I'm building kdebase now. Might take 3-4 hours or so, but seems to be chugging hard.
Building is much slower in a virtual machine. :( I think I might copy my setup to a spare drive (minus the KDE packages) so I can reboot at night to build packages faster. Or learn to setup a chroot environment. I don't have a fast second machine for this kind of project. Any suggestions?
I would go with chroot myself (and do so on the QuickBuild system). Without further information about Slackware I can't help out much more on this topic; I know Debian provides a tool that can create a minimal chroot image given only the release codename and URL to package repository. Perhaps Slackware has something similar?
Once you have the chroot, it is very simple to use: chroot /path/to/chroot/root/directory
Then do whatever compilations, etc. inside that shell. When done, a simple "exit" command will return you to the host system.
