[Plib-users] PLIB (pui) + SDL?

[Alberto B. <is...@fr...>]

Hello,
	I'm trying to use PUI inside an SDL+openGL application, but my 
compilation fails with:

MapUI.o(.gnu.linkonce.t._Z9puInitSDLv+0x15): In function `puInitSDL()':
/usr/lib/gcc/i586-mandrake-linux-gnu/3.4.1/../../../../include/c++/3.4.1/bits/stl_algobase.h:156: 
undefined reference to `puSetWindowFuncs(int (*)(), void (*)(int), void 
(*)(int*, int*), void (*)(int, int))'
MapUI.o(.gnu.linkonce.t._Z9puInitSDLv+0x1d): In function 
`std::basic_ostream<char, std::char_traits<char> >& operator<< 
<int>(std::basic_ostream<char, std::char_traits<char> >&, _xypoint<int> 
const&)':
/usr/include/plib/puSDL.h:51: undefined reference to `puRealInit()'

(MapUI.o is my object file, the source, MapUI.cpp only contains an 
#include <plib/pu.h> and a call to puInit(), for now).
I could not find anything similar by searching with google, but a lot of 
places seem to indicate that plib should work find with SDL... what am I 
doing wrong?
(I'm running Mandrake10.1, i586 version, I tried both the plib-devel 
package provided by mandrake and I recompiled plib myself).

Thanks in advance,
Alberto

Does your file contain "#include <SDL.h>" *before* you include
pu.h? Have you set the #define PU_USING_SDL?

I'm currently integrating PUI into an SDL application, so I can
assure you it works. I had some trouble compiling the SDL-example
from the PLIB-CVS (only showed a black screen), but in my
application it works fine.

In your MapUI.cpp you should have lines like this:

#include <SDL.h>
#include <plib/pu.h>

SDL.h must be included before pu.h! Then, make sure that
your CFLAGS and LFLAGS contain all necessary stuff for SDL
(sdl-config --cflags and sdl-config --libs). Add a compiler
switch which defines the above mentioned macro. For gcc this
would be: -DPU_USING_SDL
Last, make sure to link plibpu, plibul and plibfnt to your
application.

Kind regards,
Jan
