/* Override any gcc2 internal prototype to avoid an error.  */
#ifdef __cplusplus
extern "C"
/* We use char because int might match the return type of a gcc2
    builtin and then its argument prototype would still apply.  */
char sin();

int main() {
; return 0; }

Commenting out line 2054 of configure (ADDCFLAGS="$ADDCFLAGS -mieee-fp") fixes this problem. Note that I'm using gcc-3.4.1-r2 on ppc.

Reproducible: Always
Steps to Reproduce:
Comment 1 Joe Jezak (RETIRED) gentoo-dev 2004-12-12 06:31:07 UTC
This dies because -mieee-fp isn't a valid flag for ppc.  After this fix, the game still isn't playble here, I get segfaults when the race starts.  John did you get the game to actually work?
Comment 2 John Steele Scott 2004-12-13 00:07:47 UTC
I'm pretty sure that I did get this game to run, but I got rid of it because it wasn't much fun playing with the keyboard . . . probably would be fun with a steering wheel though.

Sorry I can't provide any more useful information.
Comment 3 Michael Hanselmann (hansmi) (RETIRED) gentoo-dev 2004-12-17 14:28:23 UTC
WONTFIX because it doesn't run on ppc after fixing. Maybe a future version.

Created attachment 83761 [details]
emerge -epv torcs

There are some "error" messages because my portage tree is too outdated (because I don't have internet in that computer :(  )

Thanks alot
