The contents of /usr/include/asm/ are linked to /usr/include/asm-x86_64 by multilib. However, they are defined as user includes and not system includes. For example, /usr/include/asm/errno.h contains the following: /* Common header file autogenerated by create_ml_includes in multilib.eclass */ #ifdef __i386__ #include "../asm-i386/errno.h" #endif /* __i386__ */ #ifdef __x86_64__ #include "../asm-x86_64/errno.h" #endif /* __x86_64__ */ However, on my x86 system it has the following: #ifndef _I386_ERRNO_H #define _I386_ERRNO_H #include <asm-generic/errno.h> #endif The significance of the above is the the <> denotes a system include and the "" denotes a user include. If anyone passes the "-I-" flag into gcc, the user include files will not be included and gcc will not be able to find the files (Xen is currently doing this). I hand patched some of the files, and the problem is fixed. Multilib needs to be changed to generate the files properly. Reproducible: Always Steps to Reproduce: To reproduce this problem with Xen: 1. Download the latest source tarball from http://www.cl.cam.ac.uk/Research/SRG/netos/xen/downloads/xen-unstable-src.tgz and un-tar the file. 2. build Xen ("make all") Actual Results: The make will break in mbootpack with the following error: gcc -Wp,-MD,.mbootpack.o.d -Wall -Wpointer-arith -Wcast-qual -Wno-unused -Wno-format -Wmissing-prototypes -pipe -O3 -I. -I- -c mbootpack.c -o mbootpack.o In file included from /usr/include/linux/errno.h:4, from /usr/include/bits/errno.h:25, from /usr/include/errno.h:36, from mbootpack.c:37: /usr/include/asm/errno.h:7:33: ../asm-x86_64/errno.h: No such file or directory In file included from mbootpack.c:45: /usr/include/asm/page.h:7:32: ../asm-x86_64/page.h: No such file or directory make: *** [mbootpack.o] Error 1 If you modify errno.h and page.h to be <asm-x86_64/page.h> (and <asm-x86_64/errno.h>) instead of "../asm-x86_64/page.h", then everything works. Expected Results: the compile should complete properly
This was fixed some time ago, please re-emerge linux-headers and/or glibc as neccessary. *** This bug has been marked as a duplicate of 87560 ***
linux-headers fixed it. Sorry for the dupe.
Closing bug
