# Temporary build locations:

# ARM patches:

# See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=653457
# We tried the Debian patch but we needed to remove all of these flags from the source
# and sed is better placed to do that:
fgrep -lr -- '-nodefaultlibs -nostdlib' . | xargs sed -i 's?-nodefaultlibs -nostdlib??g'

# Refresh to support latest architectures:
slackupdatelibtool

# Apply generic Slackware packaging policies:
cd $PKG
slackstripall   # strip all .a archives and all ELFs
slack_delete_lafiles # delete usr/lib{,64}/*.la
slackgzpages -i # compress man & info pages and delete usr/info/dir

slackdesc       # install slack-desc and doinst.sh
slackmp         # run makepkg -l y -c n

# Perform any final checks on the package:
cd $PKG
slackhlinks     # search for any hard links
