Graphic library will be vlf.
i thought to load modules (in this example Plugin.prx) and call functions stored inside those.
this is the situation:
main module that loads all other submodules + vlf lib.
calling vlf functions from inside the main module is (ofcourse) everything ok.
BUT if i try to call a vlf function from a submodule it doesn't work.
here the main module (main.c)
Code: Select all
#include <pspkernel.h>
#include <pspctrl.h>
#include <pspsdk.h>
#include <string.h>

PSP_MAIN_THREAD_ATTR(0);
int addText();
int OnCrossPress(void *param)
{
sceKernelExitGame();
return VLF_EV_RET_REMOVE_HANDLERS;
}
int OnSquarePress(void *param)
{
addText();
return VLF_EV_RET_NOTHING;
}
int app_main()
{
void *bi;
//vlfGuiSetBackgroundPlane(0xFF000000);
vlfGuiSetBackgroundSystem(0);
vlfGuiCacheResource("system_plugin");
vlfGuiCacheResource("system_plugin_fg");
vlfGuiSetModelSystem();
vlfGuiAddBatteryIconSystem(&bi, 10*1000*1000);
vlfGuiAddClock();
vlfGuiAddEventHandler(PSP_CTRL_CROSS, -1, OnCrossPress, NULL);
vlfGuiAddEventHandler(PSP_CTRL_SQUARE, -1, OnSquarePress, NULL);
while (1)
{
vlfGuiDrawFrame();
}
return 0;
}

in this case a module called Plugin.prx that SHOULD display a text on the screen but it doesn't work (lol)

please try to help me solve this problem.
