Brown 0 siblings, 1 reply; 7+ messages in thread From: rutger @ 2004-04-04 20:11 UTC (permalink / raw) To: qemu-devel Hi, I cannot get qemu to build on Gentoo ~x86. Is has to do with the known problem that alsa-lib is not build staticly, and therefore libsdl.a cannot be linked to, and therefore qemu cannot be build staticly also.

I tried './configure --no-static', which gives 'static build no' (but then again, that's no different from when I remove the --no-static), but the build command still fails.

If I used a static build there was certainly a reason :-) So you should better not compile qemu-fast if your distribution has not the right packages, as it it said in the (new) QEMU FAQ... Fabrice.
