N Sep 17 8791 Sam Lantinga Re: tks source released Date: Sun, 07 Sep 2003 02:51:58 +0200 From: Stephane Marchesin Subject: [SDL] Two little patches Compiling SDL with a recent gcc (gcc 3.3.1, 3.3 doesn't have this behaviour) gives some nasty warnings : SDL_blit_A.c: In function `BlitRGBtoRGBSurfaceAlpha128MMX': SDL_blit_A.c:223: warning: integer constant is too large for "long" type SDL_blit_A.c:225: warning: integer constant is too large for "long" type SDL_blit_A.c:227: warning: integer constant is too large for "long" type [...] The first attached patch (longlongfix.patch) tells gcc to really treat those constants as unsigned long long and not long. The second patch (nasinclude.patch) fixes an include problem I had while compiling nas audio : when the <audio/audiolib.h> file lies in /usr/X11R6/include, a -I/usr/X11R6/include option is needed or the file isn't found.
