Problems installing Allegro with DJGPP

Problems installing Allegro with DJGPP

Some months ago I installed succesfully Allegro on my old desktop computer. Now I am trying to install it on my Toshiba laptop. I use Windows 98, but I want to use Allegro with DJGPP. I have succesfully installed DJGPP and set correctly the environment variables, but when I try to compile allegro, the following error message appears:

====================
Compiling Allegro for djgpp, optimised. Please wait...
gcc -DALLEGRO_SRC -Wall -Wno-unused -mcpu=pentium -O2 -funroll-loops ~~ffast~~
math
-fomit-frame-pointer -I. -I./include -o obj/djgpp/alleg/allegro.o -c

ist'
c:/djgpp/include/stdio.h:35: previous declaration of `va_list'
make.exe: *** [obj/djgpp/alleg/allegro.o] Error 1
====================

Does anyone know how can I solve this problem?

Thanks!

Rash, could you possibly create a simple HTML page that explains the problem and shows the fix in a step-by-step page. If you e-mail that to me, I could place it on Allegro.cc for easy reference. It's bound to keep coming up again & again.

I'd do it myself, but I don't have DJGPP or Windows 98.

Ok, I'm going to try to make this sound as simple as possible:

Go inside the main directory where you have installed DJGPP.
Then go inside the subdirectory named include.
Finally, go inside the subdirectory named sys.
Edit the file there named djtypes.h.
Find the following line (let's call this line 15, after its current position):

#define __DJ_va_list  typedef void *va_list;

Add the following before line 15:

#if __GNUC__>=3
#define __DJ_va_list    typedef __builtin_va_list va_list;
#else

Add the following after line 15:

#endif

Save the file. ::)

If anyone manages to not understand this, then you have my sympathy.

What version(s) of DJGPP/gcc does this affect? Is there an official upgrade available yet that fixes this issue?

The patch is necessary for GCC 3.1, but from the looks of the macro it seems to affect all 3.x versions, so Your Mileage May Vary(tm).
As far as DJGPP itself is concerned, that would be version 2.03. Hopefully, 2.04 will make this thing a non-issue.

You're looking at it.

My DJGPP, shipped with gcc 3.0.3, isn't affected.

Nice sig Rash
