Description Roland Mainz 2005-04-02 12:39:58 UTC 
While crawling through my log of todays Solaris build (Solaris 8 build with Sun
Workshop/Forte 9) I saw this:
-- snip --
Scanning miext/damage/libdamage.so ...
Scanning ../../lib/font/bitmap/module/libbitmap.so ...
Scanning ../../lib/font/Type1/module/libtype1.so ...
Scanning ../../lib/font/FreeType/module/libfreetype.so ...
Xorg : __1cG__CrunMdo_exit_code6F_v_ - not found
-- snip --

The warning is about a C++ symbol...
-- snip --
% dem __1cG__CrunMdo_exit_code6F_v_
__1cG__CrunMdo_exit_code6F_v_ == void __Crun::do_exit_code()
-- snip --
... which looks suspicious for me as the Xserver code is AFAIK all plain ANSI-C.

I am not sure whether this issue is just a warning which can safely be ignored
or a sign of something more worse...

Steps to reproduce:
% export CVSROOT=:pserver:anoncvs@cvs.freedesktop.org:/cvs/xorg
% timex nice make World 2>&1 | tee -a buildlog.log

check the link line for libfreetype.so, make sure you're not using c++ to link.
Comment 2 Adam Jackson 2005-08-28 14:33:14 UTC 
reopen with more info if this still happens with 6.9.

I still see this warning in builds of CVS head on Solaris 10 x86 with the 
Sun Studio 10 compilers.   I can see the symbol in the Xorg binary:

% nm Xorg | grep -i crun
[5714]  |         0|       0|NOTY |WEAK |0    |UNDEF|__1cG__CrunMdo_exit_code6F_v_

but I don't see it in any of the .o files under xc/programs/Xserver or any of the
other files Xorg lists on the command line when linking.   I'm not sure where it's
coming from.   The only place I can find any C++ symbols is in libGLU, but that's
not linked into the server.

If it's a compiler thing, then it's a weird one, since it only appears in a
small subset of programs, mostly those having something to do with fonts - but
also xkbcomp & xcursorgen:

% find exports/bin -type l | xargs nm -A | grep Crun
exports/bin/bdftopcf: [72]      |         0|       0|NOTY |WEAK |0    |UNDEF 
|__1cG__CrunMdo_exit_code6F_v_
exports/bin/fc-cache: [86]      |         0|       0|NOTY |WEAK |0    |UNDEF 
|__1cG__CrunMdo_exit_code6F_v_
exports/bin/fc-list: [46]       |         0|       0|NOTY |WEAK |0    |UNDEF 
|__1cG__CrunMdo_exit_code6F_v_
exports/bin/mkcfm: [403]        |         0|       0|NOTY |WEAK |0    |UNDEF 
|__1cG__CrunMdo_exit_code6F_v_
exports/bin/mkfontscale: [144]  |         0|       0|NOTY |WEAK |0    |UNDEF 
|__1cG__CrunMdo_exit_code6F_v_
exports/bin/xkbcomp: [384]      |         0|       0|NOTY |WEAK |0    |UNDEF 
|__1cG__CrunMdo_exit_code6F_v_
exports/bin/xcursorgen: [51]    |         0|       0|NOTY |WEAK |0    |UNDEF 
|__1cG__CrunMdo_exit_code6F_v_
exports/bin/ucs2any: [106]      |         0|       0|NOTY |WEAK |0    |UNDEF 
|__1cG__CrunMdo_exit_code6F_v_

It doesn't seem to be causing any actual problems (it is a weak symbol after
all), but it is weird.

Any differences using a current version of xorg?
Comment 5 Timo Jyrinki 2007-02-22 14:26:45 UTC 
Marking broken (status null/blank) bugs in xorg with no activity in a long time as fixed. Please reopen if you think it's necessary, but first do a search if a similar bug report is already filed and in a NEW/ASSIGNED state. These bugs do not currently show in most search results as they do not have any status.
