Description of problem:
conflicting types for `wchar_t' in /usr/X11R6/include/X11/Xlib.h
Version-Release number of selected component (if applicable):
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 -
ATALOG -Dlinux -D__i386__ -D_POSIX_C_SOURCE=199309L -D_POSIX_SOURCE -
E=500L -D_BSD_SOURCE -D_SVID_SOURCE -I/nice/nice.v2/LINUX_V8/inc -
11 -I/usr/X11R6/include -L/nice/nice.v2/LINUX_V8/lib -L/usr/X11R6/lib -
11 -lXm -lXp -lXt -lSM -lICE -lXext -lX11 -lXt -lX11 -c UxXt.c
Actual Results: In file included from /usr/X11R6/include/X11/Intrinsic.h:56,
/usr/X11R6/include/X11/Xlib.h:78: conflicting types for `wchar_t'
This is an XFree86 thing.
/* replace this with #include or typedef appropriate for your system */
typedef unsigned long wchar_t;
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.
