2 options for uninstalling compiled from scratch software if the source dir is still available:
Code:
cd /the/dir/containing/the/source/files
make uninstall
Or avoid this and make a package of your compiled source using the checkinstall package (in the extra dir on the slackware disks) . Instead of typing 'make install' you can type 'checkinstall' and a removeable package will be installed.
A package can be removed using
Code:
removepkg /var/log/packages/<package name>
All installed packagenames are listed there.
