Can't Compile Gpu940

[efegea]

After a while I decided to start coding again, for the GBAX compo.

But gpu940 fails to compile

(Didn't read it, wnet to sleep at 6:33am, so..)

Are you using ASSERT() or assert() or the like? (Or depending on code that does)? Maybe you can avoid it, or supply the __assert_fail handler?

It's not my code, it's the gpu940 library.

Grab the precompiled version.

It might be that you have an older gcc (3.x).

Good luck. Any hints on what you are working on?

I have a 4.0.2 gcc from open2x project, I have compiled gpu940 before, but now I can't.

I prefer to compile the CVS version than using precompiled binaries.


I'm working in a 3D engine for a game. I have not touched the code in a while (about 4 or 5 months) but now I'm going to code again for the GBAX, well, I want to, because I'm laaaazyy. The actual code can show animated Quake2 models on the GP2X But now I'm going to rewrite it...

Oh, and the game...my original idea was a survival horror game.

Here, you are compiling for the gp2x. In general, when compiling for the GP2X, I always define NDEBUG, so that all the assert() calls vanish. Normally, the gp2xenv.sh scripts does this, by defined CFLAGS with "-DNDEBUG" (amongst many other things).

I suggest you source this script before running make.

I also suggest you give a try to the gpu940 user mailing list if you plan to work with the lib
(https://mail.gna.org/listinfo/gpu940-users/)

I already did that. I have compiled gpu940 a lot of times :lol:

I'm suscribed to the list. But there is not traffic since a few months ago, or I am unsuscribed?

I sent a mail to the list a few months ago but never got answer :blink: (the subject was: "black screen")

I'm also now newly subscribed to the list... I really want to do some nice 3D projects in the future (after I've got my entry for the GBAX comp out of the way)

So you have a NDEBUG preprocessor constant defined ? But gcc nonetheless introduces some calls to __assert_fail() ??
That's very surprising.

Yes, there are no traffic since several months.
Probably because there are no more bugs anymore
Or because I didn't implement much new things lately :-(

Yeah your mail is in the archive. I remember having read it (and I think I fixed the problem in the Makefiles you
reported at that time), but you are right that nobody inquired much about your black screen problem.
Does it still occur ?

 

[efegea]

I have solved the problem, now compiles and works (no black screen!) It was a problem with my modifications of the gp2xenv file. I had commented out the CFLAGS line >_<
