It looks as if your /usr/lib/libpthread.so may be incompatible with the version against which APR was built. Possibly you need to reinstall APR, preferably without anything C++-ish in the build. And 'update all' with your package manager first, to reduce the likelihood of being hit with similar problems in future! -- Nick Kew --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
