I was trying to upload the binary package to www.linuxsir.cn.
But I am not able to make a FTP connection (Timeout when login).
So I am going to post how to build a SCIM package under Slackware.
change to root user
type umask to make sure your umask is set to 0022
type chmod u+x SlackBuild.*
type ./SlackBuild.scim to build scim
the package will be in /tmp/scim-0.8.1-i486-1.tgz
type installpkg /tmp/scim-0.8.1-i486-1.tgz
type ./SlackBuild.scim-tables
type installpkg /tmp/scim-tables-0.3.0-i486-2.tgz
