Hello Stefano,
Take a look at my SlackBuild generator (which I recently made public after a fellow TDE user asked me for it):
https://github.com/blu256/tde-slackbuild-gen
Just checked and it built smb4k fine.
``` $ git clone https://github.com/blu256/tde-slackbuild-gen $ git clone http://mirror.git.trinitydesktop.org/gitea/TDE/smb4k $ tde-slackbuild-gen/gentdesb smb4k $ su -c "bash smb4k.SlackBuild" ```
If build is successful then the package should be saved as /tmp/smb4k-git-x86_64-1_tde.tgz and then you can run `installpkg [path to package]`.
Let me know if it works or if you need help with it.
