# Slackware build script for idesk

# Disclaimer:

# idesk is old and unmaintained. I wrote this SlackBuild at the request
# of someone on IRC, and decided "what the hell, I'll submit it". If
# you're reading this because you want to change anything about it, you're
# welcome to take over maintenance of this build (seriously, I don't use
# idesk, beyond running it once and seeing that it worked). The only
# maintenance I'll ever do for this build is to fix any build problems
# on future versions of Slackware (unless upstream suddenly releases a
# new version, but it's been a dead project for almost 10 years now).

# missing #include files, newer g++ cares more than the ones from 2005.
patch -p1 < $CWD/compilefix.diff

# The next two stanzas allow the program to start up without the user
# having to create or edit any config files. It won't *do* much but at
# least we can tell if it works or not. This seems like a minor deviation
# from the Slackware way, but in reality it lets me automate my testing
# so it ultimately increases the amount of slack in the universe.

# don't abort if ~/.idesktop/ dir doesn't exist (just create it). Seriously,
# that almost belongs on thedailywtf.
patch -p1 < $CWD/create_user_dir.diff

# don't reference /usr/local in default.lnk (which gets installed in
# /usr/share/idesk as well as /usr/doc). Also use kdialog for the
# "about" icon, as Slackware doesn't ship Xdialog.
