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. Actual Results: In file included from /usr/X11R6/include/X11/Intrinsic.h:56, from UxXt.c:25: /usr/X11R6/include/X11/Xlib.h:78: conflicting types for `wchar_t' /usr/lib/gcc-lib/i386-redhat-linux/3.2/include/stddef.h:294: previous declaration of `wchar_t' Additional info:
This is an XFree86 thing.
#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
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.
