Hi, I’m trying to build pjsip 2.9 on CentOS 6 which has gcc 4.4.7. It fails with this error… gcc -o ../bin/pjmedia-test-x86_64-unknown-linux-gnu \ output/pjmedia-test-x86_64-unknown-linux-gnu/codec_vectors.o output/pjmedia-test-x86_64-unknown-linux-gnu/jbuf_test.o output/pjmedia-test-x86_64-unknown-linux-gnu/main.o output/pjmedia-test-x86_64-unknown-linux-gnu/mips_test.o

Before I set off working out how to do either of those, I thought I’d ask as someone is bound to know exactly where to do that
😉 gcc -v reports … gcc -v Using built-in specs. Target: x86_64-redhat-linux Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --with-bugurl=http://bugzilla.redhat.com/bugzilla --enable-bootstrap --enable-shared --enable-threads=posix
