Bug 114767 – x11-base/xorg-x11-6.8.2-r4 compile error

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Thomas Cort (RETIRED) 2005-12-07 08:50:47 UTC]

I setup a chroot using the 2005.1 stage3 alpha tarball, emerge sync'd, updated
the system with emerge -uD world, ran gcc-config pyton-updater etc-update etc.,
and then tried emerging xorg-x11. I got the compile error below...

Reproducible: Always
Steps to Reproduce:
1. emerge xorg-x11

[Comment 1 Joshua Baergen (RETIRED) 2005-12-07 09:18:14 UTC]

This looks like a linux-headers problem on alpha.  Alpha team, have you seen
this before?

[Comment 2 Thomas Cort (RETIRED) 2005-12-10 05:51:16 UTC]

All of the syntax errors in bitops.h are because linux-headers uses inline
functions and xorg uses the -ansi CFLAG. "C++, C99, and GNU C each have support
for inline functions, although 1990 ANSI C, the dialect of C most commonly used
in practice, does not." [1]

I created a simple program[2] with an inline function. It compiles without -ansi
and gives that informative "error: syntax error" when I use -ansi.

I tried xorg-x11-6.8.2-r6 and linux-headers-2.6.11-r3, and I got the same syntax
errors. Anyone have ideas on a possible fix for this?

[Comment 3 Thomas Cort (RETIRED) 2005-12-13 08:57:37 UTC]

I looked into this further and found that the exact problem with linux-headers
is asm-alpha/compiler.h. You see asm-alpha/bitops.h includes
asm-alpha/compiler.h which includes linux/compiler.h which contains a macro that
#define's inline as __inline__ if gcc >= 3.1. asm-alpha/compiler.h #undef's
inline which causes the compile error on the inline functions. This is because
gcc's -ansi flag (used by Xorg) works with __inline__ functions, not inline
functions.

This isn't a problem for i386 because inline is #undef'ed in
asm-alpha/compiler.h. i386 doesn't have an asm-i386/compiler.h, it just includes
linux/compiler.h.

I hope that wasn't too confusing. I'll be e-mailing <a
href="http://lkml.org/">LKML</a> to see if they can fix this header issue.

[Comment 4 Thomas Cort (RETIRED) 2005-12-13 09:14:55 UTC]

Before e-mailing the LKML I tried the latest headers from linux-2.6.15-rc5-git3
and they solved the problem.

[Comment 5 Joshua Baergen (RETIRED) 2005-12-13 09:31:00 UTC]

Thank you for looking into that Thomas.  This means we need to have
sys-kernel/linux-headers bumped, correct?

[Comment 6 Thomas Cort (RETIRED) 2005-12-13 09:53:38 UTC]

> This means we need to have sys-kernel/linux-headers bumped, correct?
Yes that is correct. linux-headers-2.6.11-r3, the latest linux-headers in
portage, does not include the fix.

[Comment 7 Thomas Cort (RETIRED) 2005-12-13 09:55:56 UTC]

> sys-kernel/linux-headers bump
I looked through the kernel changelogs and sources and I believe it should be
fixed in 2.6.14.

[Comment 8 Joshua Baergen (RETIRED) 2005-12-13 09:59:07 UTC]

You're handy ;)

Plasmaroo, I believe this is your bag.

[Comment 9 Tim Yamin (RETIRED) 2005-12-20 07:37:59 UTC]

Please try sed -i -e 's/ inline / __inline__ /g' /usr/include/asm/bitops.h /usr/include/linux/bitops.h /usr/include/linux/wait.h - should hopefully fix the issue.

[Comment 10 Thomas Cort (RETIRED) 2005-12-20 10:07:01 UTC]

It worked, thanks!

[Comment 11 Tim Yamin (RETIRED) 2005-12-21 16:52:50 UTC]

Fixed in 2.6.11-r4; thanks!
