Bug 51261 – qemu doesn't compiles due to lost #include <errno.h>

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description BigBug 2004-05-17 02:16:38 UTC]

can't compile qemu 0.5.5 due to lost #include <errno.h> in target-i386/helper2.c, adding this #include solves the problem.

Problem may be releated to something else? ;/

Reproducible: Always
Steps to Reproduce:




Portage 2.0.50-r6 (default-x86-1.4, gcc-3.3.2, glibc-2.3.3_pre20040420-r0,
2.6.6-love1)

I'll take a look, how it fails w/out it?

which targets did you enable?

Strangely enough I did a grep for errno in the qemu tree and in that file errno isn't present a all.

looks like you have somewhat messed up includes, maybe bogus kernel includes?

yes, my kernel-headers is broken ;) sorry
