Broken linux/byteorder.h in kernel-headers-2.6.29*
Last modified: 2009-01-08 17:00:15 EST
Description of problem: With the recent endian changes in kernel headers it is not possible to compile glibc and I guess plenty of other stuff. glibc build fails with: In file included from /usr/include/asm/byteorder.h:63, from /usr/include/linux/atalk.h:4, from ../sysdeps/unix/sysv/linux/netatalk/at.h:25, from ../sysdeps/unix/sysv/linux/sa_len.c:22: /usr/include/linux/byteorder.h:8:3: error: #error Fix asm/byteorder.h to define one endianness I guess #include <endian.h> #include <asm/byteorder.h> should be enough to reproduce it. The problem is that the new kernel headers now use __BIG_ENDIAN or __LITTLE_ENDIAN macros to determine if target is big or little endian. Unfortunately, this clashes with glibc __BIG_ENDIAN and __LITTLE_ENDIAN macros that are in use for years. Kernel expects only one to be defined, while glibc always defines both (well, also __PDP_ENDIAN) and then defines __BYTE_ORDER to the one that is used for the arch in question. I'd say the kernel, at least for #ifndef __KERNEL__, should use different macros than __BIG_ENDIAN and __LITTLE_ENDIAN (add __ at the end or something similar). Version-Release number of selected component (if applicable): 2.6.29-* How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:

This problem block busybox build too :(: In file included from /usr/include/asm/byteorder.h:63, from /usr/include/linux/ip.h:20, from /usr/include/linux/if_tunnel.h:5, from networking/libiproute/iptunnel.c:24: /usr/include/linux/byteorder.h:8:3: error: #error Fix asm/byteorder.h to define one endianness

Bump. I can't build MPlayer because of that.
My testcase: $ cat test.c #include <sys/types.h> #include <linux/cdrom.h> $ gcc -o test test.c In file included from /usr/include/asm/byteorder.h:63, from /usr/include/linux/cdrom.h:14, from test.c:2: /usr/include/linux/byteorder.h:8:3: error: #error Fix asm/byteorder.h to define one endianness $ rpm -q kernel-headers kernel-headers-2.6.29-0.12.rc0.git7.fc11.i386
Fixed upstream, patches (comment #4) merged into latest git. Next kernel update should get us the fix too.
Should be fixed in kernel-2.6.29-0.15.rc0.git9.fc11 (currently headed to the build system) and later.
FYI I just did a KVM build, with kernel-headers 2.6.29-0.19.rc0.git9.fc11 in the build root and it now works fine, so looks like this resolved it.
It seems to be fixed, thanks.
