I was compiling alsa-driver on my new Gentoo, when i got that...

Any ideas what's wrong?

Looks like you've got problems from having different programmes compiled with different compilers (and possibly versions of glibc).

The way that I'd do it is to make sure that my compiler and glibc are up to date, re-build and install the kernel (and modules) and then try to compile the extras.

I did that, but i still get the same problem. Any other ideas? What else should I try?

I'm not that familiar with compiling Alsa and this looks like it may be an Alsa specific problem.

I put your error message into Google and found this thread on the Alsa list which may be of help:
<http://www.mail-archive.com/alsa-use.../msg09589.html>

I have had reasonable success in finding solutions just by cutting and pasting the error message into my GoogleBar.

I solved my problem. In /usr/src/linux/include/linux/compile.h file under #define LINUX_COMPILER "gcc" i set this gcc, before that it was empty.

TNX kbcnetau, I owe you one.
