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

Debugging with gdb gives:
| Code: | 153 sceGuInit();
(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: | 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) |
