I am having some trouble with psp-gdb. I am trying to debug a simple hello world app just to get things setup. I cant seem to get this to compile with debug symbols though. Whenever I start debugging and type "info locals" while I am in main, it tells me "No locals." Am I doing something wrong? When I compile the sprite sample with -g and debug it, the symbols show up fine when I type "info locals" in main.

Code:
#include <pspkernel.h>
#include <pspdebug.h>

PSP_MODULE_INFO("HelloWorld_cpp",0,1,1);
PSP_MAIN_THREAD_ATTR(THREAD_ATTR_USER);

#define printf pspDebugScreenPrintf

int global = 0;


int main() {

   int var1=0;

    pspDebugScreenInit();

    printf("Hello World\n");

   var1 = 1;
   var1 = 2;
   global = 2;

   printf("after vars\n");

    return 0;
}


Code:
TARGET = helloworld
OBJS = main.o

CFLAGS = -g -O2 -G0 -Wall
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)

LIBDIR =
LIBS = -lm -lpspaudio -lpspgu -lpsppower -lpsprtc -lstdc++
LDFLAGS =

EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = Hello World

PSPSDK=$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build.mak

Remove -O2 from your CFLAGS, gcc optimises locals to registers which means gdb cannot seem them.
