Exception - Syscall: can't find what I'm doing wrong :(

Hi.

I'm debugging a homebrew, and I'm getting this error when I run it with linkusb:

Debugging with gdb gives:

(gdb) 
154		sceGuStart(GU_DIRECT, list);
(gdb) 

Program received signal SIGHUP, Hangup.

(BTW, this is the bookr_djvu sources). I checked my sdk installation, and everything seems fine: it is the latest version and sdk/samples/gu work fine. Is this a known problem? Can someone point me to some actions to debug this?

Thanks.

I'm answering my own post: the problem that heap size was too small. With

Code: Select all

PSP_HEAP_SIZE_KB(2048);

everything is fine.

Which is why many devs wait a day or two before answering. Many times, an answer isn't needed. Not if the person really is serious about being a developer themselves.

Good job on working it out on your own. You'll do fine here. 8)
