25 Jan 2006 I recompile libpng since the package supplied with Slackware gives problems when compiling some software: It may just be that the libs are overstripped since some programs, such as fblogo, need the re-compiled libpng *.so libs in order to compile, but fblogo runs with the standard Slackware libs. (Similar case with ORBit-libs). I use a different source-tarball than slackware, which uses the pre-configured version. If you don't like over-writing your Slackware packages, configure with --prefix=/usr/local. Or, just recompile libpng, copy to some place convenient and pass the LD_LIBRARY_PATH pointing to these when configuring and/or compiling: LD_LIBARY_PATH=/pat/to/libpng ./configure LD_LIBARY_PATH=/pat/to/libpng make
