From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.0; Windows 98; DigExt) Description of problem: conflicting types for `wchar_t' in /usr/X11R6/include/X11/Xlib.h and /usr/lib/gcc-lib/i386-redhat-linux/3.2/include/stddef.h Version-Release number of selected component (if applicable): gcc-3.2-7.src.rpm How reproducible: Always Steps to Reproduce: 1. I can not simplify the program , since my program eniroment are very complicated But I list my sample : when building my library, produce following error : --- Building NdmFm LIB --- /usr/bin/cc -DLINUX_V8 -DLINUX -D_GNU_SOURCE -g -DMOTIF -DXT_CODE -DSYSV - DXOPEN_C ATALOG -Dlinux -D__i386__ -D_POSIX_C_SOURCE=199309L -D_POSIX_SOURCE - D_XOPEN_SOURC E=500L -D_BSD_SOURCE -D_SVID_SOURCE -I/nice/nice.v2/LINUX_V8/inc - I/usr/include/X 11 -I/usr/X11R6/include -L/nice/nice.v2/LINUX_V8/lib -L/usr/X11R6/lib - L/usr/lib/X 11 -lXm -lXp -lXt -lSM -lICE -lXext -lX11 -lXt -lX11 -c UxXt.c 2. 3.

This is an XFree86 thing.
Comment 2 Mike A. Harris 2003-03-20 01:37:18 UTC
#ifndef X_WCHAR #include <stddef.h> #else #ifdef __UNIXOS2__ #include <stdlib.h> #else /* replace this with #include or typedef appropriate for your system */ typedef unsigned long wchar_t; #endif #endif
Comment 4 Ulrich Drepper 2003-03-20 03:28:04 UTC
Looking at the part of the header you posted, W_WCHAR shouldn't be defined. Then wchar_t is picked up from stddef.h. Of course I don't know what other effects this will have. But I would guess nothing which conflicts or which would disable functionality.

Since this bugzilla report was filed, there have been several major updates to the X Window System, which may resolve this issue. We encourage you to upgrade to the latest version of Fedora Core (http://fedora.redhat.com). If this issue turns out to still be reproduceable in the latest version of Fedora Core, please file a bug report in the X.Org bugzilla located at http://bugs.freedesktop.org in the "xorg" component. Once you've filed your bug report to X.Org, if you paste the new bug URL here, Red Hat will continue to track the issue in the centralized X.Org bug tracker, and will review any bug fixes that become available for consideration in future updates.
