Hey, i was wondering how do you set up a cpp app in jsgf version of pspgl. In holgers version i was able to with no problem. here the patch he gave me.

And it compiles like this

i've tried implementing this into jsgf version, but certain functions where missing. i'm not at home right now so i cant post the errors i got.

I haven't done much with PSPGL and C++, but it shouldn't be too hard to make work properly.

i was wondering, since you seem to have taken over the pspgl development, if you can try yourself to see how it might fit in. i havnt given up trying yet tho, but am currently working on the 3ds loader for your version of pspgl.

Yeah, I'll take a look at it in the next couple of days.

Did you work out your file IO problem?

well i havnt had time to work too much on it. since i'm busy with university and all. but the original errors occured in holgers verion of pspgl. So i'm right now slowly coding one using your version of pspgl. but i'm probably going to finish it up during the weekend.

Okay, been working on a pspgl cpp for jsf version. Heres what i got so far

Code:
psp-g++ -g -Wall -O2 -MD -MF .deps/glut.d -I.. -I/usr/local/pspdev/psp/sdk/inclu
de -c glut.cpp
glut.cpp:214:3: warning: no newline at end of file
psp-gcc -g -Wall -O2 -MD -MF .deps/psp-setup-glut.d -I.. -I/usr/local/pspdev/psp
/sdk/include -o psp-setup-glut.o -c -DMODULE_NAME="glut" psp-setup.c
psp-gcc -o glut.elf -g -Wall -L.. -stdc++ -L/usr/local/pspdev/psp/sdk/lib glut.o
 psp-setup-glut.o  -lpng -lz -lglut -lGLU -lGL -lm -lc -lpsputility -lpspdebug -
lpspge -lpspdisplay -lpspctrl -lpspsdk -lpsplibc -lpspuser -lpspkernel -lpsprtc
glut.o:(.eh_frame+0x11): undefined reference to `__gxx_personality_v0'
collect2: ld returned 1 exit status
make: *** [glut.elf] Error 1
rm psp-setup-glut.o


Not quite sure what the error is. So i'll post my source online. This includes a Make file. so you just just toss it in the pspgl directory.

http://www.geocities.com/tsune_l/test-cpp.zip

This is based off my BMP loader available at
http://forums.ps2dev.org/viewtopic.php?t=4487

the only think i really did was replace

Code:
extern "C" void __pspgl_log (const char *fmt, ...);


in line 10, in glchk.h file. and added extern "C" in the cpp file.

here what i did in the make file

Code:

Not quite sure what the error is.
Put -lstdc++ at the end. Or use psp-g++. Also read http://forums.ps2dev.org/viewtopic.php?p=23298#23298.

The error is caused by not having the correct library order. Read the post jimparis referred you to or keep fiddling with the order until it works.

problem solved. i just placed the -lstdc++ before the -lc and it works. thanks for all the help.

Code:
PSPGL_LFLAGS = -lglut -lGLU -lGL -lstdc++ -lm -lc -lpsputility -lpspdebug -lpspge -lpspdisplay -lpspctrl -lpspsdk -lpsplibc -lpspuser -lpspkernel -lpsprtc

Okay, Now it compiles just fine, but when i run it. it just goes to a black screen, waits 20 secs, then turns off. does anyone know why it would do this?

Edit Fixed.
changed from this from Makefile
Code:
%.elf: %.o psp-setup-%.o ../libGL.a ../libGLU.a ../libglut.a
   $(CPP) -o $@ $(LDFLAGS) $(filter %.o,$^)  -lpng -lz $(PSPGL_LFLAGS)


to this
Code:
%.elf: %.o psp-setup-%.o ../libGL.a ../libGLU.a ../libglut.a
   $(CC) -o $@ $(LDFLAGS) $(filter %.o,$^)  -lpng -lz $(PSPGL_LFLAGS)


only supose to compile the cpp file using psp-g++. Also removed extern "C" from the glchk.h file. as it only need to be called once in the cpp file.

Here I have posted the code online for people to try it out. Its a port of my bmp loader into cpp.

Bringing this back up just for reference.

Thanks for posting the code, Thanhda. To build properly with the current version of PSPSDK, you need to link with pspvfpu also. So the line in the Makefile becomes:

Code:
PSPGL_LFLAGS = -lglut -lGLU -lGL -lstdc++ -lm -lc -lpsputility -lpspdebug -lpspge -lpspdisplay -lpspctrl -lpspsdk -lpspvfpu -lpsplibc -lpspuser -lpspkernel -lpsprtc
