Hi,
I've got a weird problem when I try to add "BUILD_PRX = 1" in my makefile.
When I add this line, my program can't access file on disk, when it try to open a file, it return NULL.
but without BUILD_PRX = 1, everything work fine

I really don't understand why it wouldn't work

this is my makefile :

New custom firmwares basically require a prx to be encapsulated into eboot. So the whole executable is like a library loader. While a program starts with a status setted by executing environment (or operating system...) a library does not, so a prx has _NOT_ (among other status variables) a Current Working Directory.....your program basically doesn't know where to find files you point out.
Solutions:
1) Provide full path filenames
2) find out cwd with some functions i don't remember at the moment (just search now that you have the "cwd" buzzword)

hope this will help!

You havent defined a heap_size

Try adding this after the module info:
PSP_HEAP_SIZE(20480);

This will define the area which the program can play with, 20mb is what is allocated in my example. However you may adjust to suit.

I Wish there was a way to rid of this heapsize bullshit for once and for all :) *Bites TyRaNiD*

thanks for your answers,

Wally meant PSP_HEAP_SIZE_KB(20480);
