I found a patch in the list that purposely was not merged into 3.5.13. The patch seems to help, but I still can't build kdevelop 3.5.13. Slackware 13.1. Log: http://humanreadable.nfshost.com/trinity/build_logs/kdevelop-3.5.13-i486-1-build.log.gz I am not seeing anything obvious in the log. Thanks. Darrell
