It might be useful, but then again, I'd expect that if as-needed and no-undefined were used there would be link failures prior to the tests being built (it bombs out much earlier for me when I do that). So the link flags would be interesting to see but unless they are different flags for the tests than for the main build then I'll be a bit confused.... But then again I make no claims to really understand linking fully :D Col -- Colin Guthrie gmane(at)colin.guthr.ie http://colin.guthr.ie/ Day Job: Tribalogic Limited [http://www.tribalogic.net/] Open Source: Mageia Contributor [http://www.mageia.org/] PulseAudio Hacker [http://www.pulseaudio.org/] Trac Hacker [http://trac.edgewall.org/]
