VLF Library problem

blu_eye4 · Post by **blu_eye4** » Tue Nov 04, 2008 3:05 am

Hi guys

Well, I've a problem: I've begun programming with vlf library so, I've made a little homebrew to test them. The homebrew works very well, but when I want to insert pspctrl.h library in the homebrew and make

Code: Select all

&#91;...&#93;if&#40;latch.uiMake != 0&#41;&#123;
           if&#40;latch.uiMake & PSP_CTRL_CROSS&#41;&#123;
            vlfGuiAddText&#40;5, 210, "Hai premuto il tasto X\n"&#41;;

   &#125;
       &#125;
       if&#40;latch.uiMake & PSP_CTRL_CIRCLE&#41;&#123;
           vlfGuiAddText&#40;5, 210, "Hai premuto il tasto O\n"&#41;;

       &#125;&#91;...&#93;

the homebrew doesn't work, and the psp give me the following error: 0x8002013C. How can I resolve? Please help me, I'm a noob in c programming language :)

this 0x8002013C whether means you are doing kernel calls or library not found

Can you post your makefile please?
Also make sure if you are not doing any kernel calls (this means not using kernel functions)

try this:
-lvlflibc -lvlfutils -lvlfgu -lvlfgui -lpng -lz -lm -lpspkubridge
instead of your LIBS

nothing, with your libs order is a mess of error...

Well I don't know the dependency tree of the vlf library so I just guessed by the name.
Just check if you are doing any kernel calls

Try and use the VLF handlers for the controller input.

im using latch functions from a separate thread, with same makefile,libs and includes folder from the vlf sample. try working up from the sample.

Thanks, but I think this is a library problem: I've tried many times and I discovered that when I include pspctrl.h library in the homebrew, the programm doesn't work, giving the error that i said before. I've tried also to include the library in the makefile but the homebrew doesn't work too! I don't know what it is the problem and I don't think that using latch function in a separate thread I will resolve the problem

Make a kernel prx with the control functions and export them into your app :)

i don't know how i have to do, can you tell me it? thanks a lot :)

Do you know how to export functions?

yes and no: i know taht i have to create a .exp file, but i don't know how get functions :(

Pirata Nervo · Post by **Pirata Nervo** » Thu Nov 06, 2008 1:31 am

Load the prx file / link the library which exports the functions.
Build a stub out of exports.exp by hitting this command:
psp-build-exports -s exports.exp
in your terminal window (make sure the current dir is the prx source dir)

thanks, but the prx i must reload from flash0 or i must create? you don't have a tutorial to link me? thank a lot :)

If you do some search over the forums you will find a few quick tutorials or samples.

You must create the prx to export your functions from there and then load that prx from your app and use its functions

oh guys, i've resolved my problems: i've made a .s file where i've include the library pspctrl.h. Now the homebrew works very well :)

If you want i'll post here how I've resolved, maybe it can be useful for a noob :)
