I thought you were intentionally ignoring me! ;) I've heard that upgrading Ubuntu is a major pain. > I tried the proxy samples and it seems to be working okay on Ubuntu > 8.04/linux 2.6.24-19, so there must be some particular setup in your box > that pjlib doesn't like.

It is still segfaulting the same way. Running ./aconfigure CFLAGS='--g' results in the following error: checking build system type... i686-pc-linux-gnu checking host system type... i686-pc-linux-gnu checking target system type... i686-pc-linux-gnu checking for gcc... gcc checking for C compiler default output file name... aconfigure: error: C compiler cannot create executables See `config.log' for more details. The reason is this: ... aconfigure:1817: gcc --g conftest.c >&5 cc1: error: unrecognized command line option "-fg" ... So I ran ./aconfigure CFLAGS='-g' And it worked fine. The problem is that I can't seem to be able to debug, because gdb doesn't find debugging symbols: filippo at asus-laptop:~/tesi/pjsip/debug/pjproject-0.9.0/pjsip-apps/bin/samples$ gdb -e stateful_proxy-i686-pc-linux-gnu GNU gdb 6.4.90-debian Copyright (C) 2006 Free Software Foundation, Inc.
