Running on Solaris 8 Sparc... ./configure --with-syslog It fails with the following: checking configure summary... configure: error: summary failure. Aborting config Lookint at the config.log file, it's clear, configure fails to find libpopt, which is installed in /usr/local/lib configure should know better and include /usr/local/lib in it's path... As a workaround I used: # LIBS="-L/usr/local/lib -R/usr/local/lib" ./configure --with-syslog Is this correct ? TIA.
