[Slackbuilds-users] XEmacs SlackBuild

Sun Aug 23 22:16:46 UTC 2009

I have an XEmacs Slackbuild file I have started modifying to more
closely fit the slackbuilds format. I hope it is ok to ask questions
here about the SlackBuild file. If not, ignore this email ;)

The file is at the bottom of the email. Please be kind, this files is
many years old and predates the SlackBuild file when the files where
all called make-slack.

1) First off, there are three patches. One of the patches just gets
shifted function keys working. This patch could very easily be mapped
out for the slackbuilds case, but I have used this patch for years with
no problems.

The other two patches allow you to build an XEmacs package while XEmacs
is installed. I could leave out the two patches, but you would have to
uninstall XEmacs to build a new XEmacs package.

2) A second problem is that I require two XEmacs packages to build the
Slackware package. These packages are required to use the XEmacs
package system. Yes, you need some packages to get the package system
going to download packages :( Adding them to the Slackware package made
sense for personal use and for Linuxpackages. I am not sure it is a
good idea to require them for the slackbuilds case since the versions
are hardcoded.

3) The website made it clear you have to set the SLKCFLAGS. I really
think this is a bad idea for XEmacs. I have a comment in the SlackBuild
file about this. How hard a requirement is this?

Cheers,
   Sean
