 |
|
alright, i've been looking around to see if people have had this same problem, and i've notice that people have. but no one really answers there question. my problem is that it cant seem to instantiate a new object into my main. basically i can create a class but when i type "testClass *test = new testClass" it doesnt seem to work. if i type "testClass *test;" it compiles. but cant access any of the members of the class.
heres what happens when i create a 'new' object

psp-g++ -I. -I/usr/local/pspdev/psp/sdk/include -O2 -G0 -Wall -I. -I/usr/local/pspdev/psp/sdk/include -O2 -G0 -Wall -fno-exceptions -fno-rtti -c -o main.o main.cpp
main.cpp: In function ‘int main(int, char**)’:

i used the "me" demo to try this. also renamed the file to main.cpp
| Code: |
#include <pspkernel.h>
#include <pspdebug.h>
#include <pspctrl.h>
#include <pspdisplay.h>
#include <stdlib.h>
#include <string.h>
/* Define the module info section */
PSP_MODULE_INFO("mebasic", 0, 1, 1);
/* Define the main thread's attribute value (optional) */
PSP_MAIN_THREAD_ATTR(0);
/* Define printf, just to make typing easier */
#define printf pspDebugScreenPrintf
void me_run(void);
void me_end(void);
class testClass
{
public:
int num;
};
int main(int argc, char *argv[])
{
SceCtrlData ctl;
testClass* test = new TestClass;
pspDebugScreenInit();
sceCtrlSetSamplingCycle(0);
sceCtrlSetSamplingMode(PSP_CTRL_MODE_DIGITAL);
/* Copy our small program into the ME reset vector */
//memcpy((void *)0xbfc00040, me_run, (int)(me_end - me_run));
sceKernelDcacheWritebackInvalidateAll();
sceSysregMeResetEnable();
sceSysregMeBusClockEnable();
sceSysregMeResetDisable();
sceSysregVmeResetDisable();
while(1)
{
volatile u32 *count = (u32*) 0xBFC00060;
pspDebugScreenSetXY(0, 0);
pspDebugScreenPrintf("ME Basic Example, press Home to exit\n");
sceKernelDcacheWritebackInvalidateAll();
pspDebugScreenPrintf("ME Counter: %08x\n", *count);
sceCtrlReadBufferPositive(&ctl, 1);
if(ctl.Buttons & PSP_CTRL_HOME)
{
sceKernelExitGame();
}
sceDisplayWaitVblankStart();
}
return 0;
}

the makefile if the same as it was default

you might want to try reordering the libraries. This is what I used in my build.mak
# Link with following default libraries. Other libraries should be specified in the $(LIBS) variable.
# TODO: This library list needs to be generated at configure time.
PSPSDK_LIBS = -lpspdebug -lpsppower -lpspdisplay -lpspge -lpspctrl -lpspaudiolib -lpspaudio -lpspsdk
LIBS := -lstdc++ -lpng -lmad -lz -lm
LIBS := $(LIBS) $(PSPSDK_LIBS) $(PSPSDK_LIBC_LIB) -lpspuser -lpspkernel
just remove any of the psp libraries you don't use. |
