# Slackware build script for doomseeker

# 20201030 bkw: updated for v1.3.1
# 20200122 bkw: updated for v1.3+20200119_b623ab1. Latest git fixes
# a segfault issue that normally only occurs when starting doomseeker
# without ~/.config/doomseeker/* (so the previous version worked for me,
# but wouldn't for a new user).
# 20191211 bkw: updated for v1.3. qt4 support was dropped, qt5 now required.
# 20181218 bkw: updated for v1.2. Upstream has changed things around,
# so this script won't build 1.1 any longer.

# 20200122 bkw: sorry, rworkman, I know you hate gzipped diffs, but
# this one has mixed \r\n and \n line endings, git would eat it.
# 20201030 bkw: leaving the diff in the repo for a while, in case
# 1.3.1 has issues and someone needs to build the previous version.
# It'll be removed at next update.
