Subject: Re: [SDL] Dynamic X11...
1. Compilation produce the following error on Tru64 UNIX.
cc: Severe: SDL_x11dyn.h, line 31: Cannot find file
<X11/extensions/extutil.h> specified in #include directive. (noinclfilef)
#include <X11/extensions/extutil.h>
Because Tru64 UNIX doesn't have extutil.h, this error is caused.
2. Compilation with --enable-x11-shared=no produce the following error.
cc: Error: SDL_x11sym.h, line 115: In this statement,
"Xutf8TextListToTextProperty" is not declared. (undeclared)
SDL_X11_SYM(int,Xutf8TextListToTextProperty,(Display*,char**,int,XICCEncodingStyle,XTextProperty*))
Though it doesn't have Xutf8TextListToTextProperty,
"pXutf8TextListToTextProperty = Xutf8TextListToTextProperty;"
in SDL_x11dyn.c,117-119
#define SDL_X11_SYM(r,fn,arg) p##fn = fn;
#include "SDL_x11sym.h"
#undef SDL_X11_SYM
