Dynamic X11

SDL Development
1

Just checked in a large patch to make SDL dynamically load the X11 libs
at runtime, to match the ALSA, etc backends.

This touched a lot of code; please report build issues so I can fix them.

Thanks,
–ryan.

  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.

  1. 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–

Is this optional? There are systems which have X11 which don’t have
shared libraries…

I put your fixes in CVS, thanks!

In SDL12/configure.in:624-629
624 x11_lib_spec=’/usr/X11R6/lib/libX11.so.'
625 x11_lib=‘libX11.so.6’
626 echo "-- $x11_lib_spec -> $x11_lib"
627 x11ext_lib_spec=’/usr/X11R6/lib/libXext.so.'
628 x11_lib='libXext.so.6’
629 echo “-- $x11ext_lib_spec -> $x11_lib”

Is x11_lib a misspelling of x11ext_lib in SDL12/configure.in,628-629 ?

Tru64 UNIX has not libX11.so.6 but /usr/shlib/libX11.so.
libXext.so.6 is also similar.–

It can be toggled in the configure script.
