If the danzeff file is .c, you need to make sure it's compiled with gcc, not g++. If you changed it to .cpp, you need the make sure you have extern "C" {} in the danzeff.cpp file AS WELL AS the h file. Otherwise, the names won't match.

BUILD_PRX means that I'm working on a PRX which I'm not (right?)

Well depends on firmware, if your fw is 1.50 then youre working on ELF, if you build for modern fw like 3xx/4xx/5xx then you need to build PRX even for EBOOTS.

At least I was told so, and it worked...

So that extern "C" {} part isn't needed if I'm working withoud renamed .cpp files?
And do you have any good article which explains that extern thingy?

As long as you also compile the .c files with psp-gcc and not psp-g++, no it's not needed. The extern "C" {} is for c++ to tell the compiler not to mangle the name as whatever is inside {} is c code with c naming conventions.

As for where it's explained, read any C++ book, specifically the part concerned with using C with C++.

I'm compiling with psp-gcc, so that can't be problem. Any other ideas?

J.F. · Post by **J.F.** » Wed Jun 24, 2009 6:38 pm

I think we need to see everything at this point. Trying to describe the problem and posting little snippets (other than the makefile) isn't getting us anywhere.

One thing, though, looking back over earlier posts - you are including libstdc++, so this should be a C++ app, however, the error quote shows the main file as main.c. It's quite possible that main is the problem. You probably need to change main.c to main.cpp and put extern "C" {} around the PSP callbacks, leaving main() as c++. Your project seems to be a crazy mix of c and c++, which is probably what is causing your trouble. Look at the main_psp.cpp from Basilisk II for an idea of how to do a C++ main for the PSP.

Here we go again:

Makefile:

Code: Select all

TARGET = GPOS
OBJS = main.o danzeff.o

LIBS = -libstdc++ -lpsprtc -lpspwlan -lpspgum -lpspgu -lpspaudio -lm -lpsppower
LIBDIR = $&#40;PSPDEV&#41;/SDK/lib

CFLAGS = -O2 -G0 -Wall
CXXFLAGS = $&#40;CFLAGS&#41; -fno-exceptions -fno-rtti
ASFLAGS = $&#40;CFLAGS&#41;

EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = GPOS

PSPSDK=$&#40;shell psp-config --pspsdk-path&#41;
include $&#40;PSPSDK&#41;/lib/build.mak

main.c: http://producted.pastebin.com/m3cc2c1ba
Don't comment on my 'bad' variable naming etc, it's still v0.1a x)

What else do you need?

J.F. · Post by **J.F.** » Thu Jun 25, 2009 11:41 pm

Well, your module info isn't complete

Code: Select all

PSP_MODULE_INFO&#40;"Name", 0, PSP_VERS, PSP_REVS&#41;;
PSP_MAIN_THREAD_ATTR&#40;PSP_THREAD_ATTR_USER&#41;;
PSP_HEAP_SIZE_KB&#40;-256&#41;;

and in the makefile right after the flags you should have

Code: Select all

BUILD_PRX = 1
PSP_FW_VERSION = 500
PSP_LARGE_MEMORY = 1

That would make an authentic 3.xx user mode app. Right now, there's no telling what your app will turn out as.

And finally, since this is C++, you need to alter the makefile to specifically use psp-gcc to compile any .c files by adding an all target to the makefile to do so. Right before the last two lines, add

Code: Select all

all&#58; main.o danzeff.o $&#40;EXTRA_TARGETS&#41; $&#40;FINAL_TARGET&#41;

main.o&#58; main.c
	$&#40;CC&#41; $&#40;CFLAGS&#41; -c $< -o $@

danzeff.o&#58; danzeff.c
	$&#40;CC&#41; $&#40;CFLAGS&#41; -c $< -o $@

If you don't specify the .c files explicitly, they'll implicitly be compiled with psp-g++ instead for c++ projects. Why are you making this a c++ project when you don't seem to have any c++ files yet?

Makefile:

Console output:

They you should be more specific with errors. :( Which / what seperator? And makefile:4 means at line 4?

And yet again, thanks that you are still helping me, even on the second page. :D

J.F. · Post by **J.F.** » Fri Jun 26, 2009 3:37 am

You need a tab to start the $(CC) lines... stupid make can't handle spaces.

Oh yess....
You haven't basically defined if you want to use DANZEFF_SDL or DANZEFF_SCEGU...
Try to define this or comment out #ifdefs it works great...
I've get this problem some months ago, but to resolve I've tried to do what you have to do....just read... ;)

Code: Select all

//Set which renderer target to build for
/* #define DANZEFF_SDL */
/* #define DANZEFF_SCEGU */

I've also hadn't read immediately...

J.F. · Post by **J.F.** » Sat Jun 27, 2009 3:31 am

Right... that was in the B2 makefile... the CFLAGS has -DDANZEFF_SCEGU as one of the CFLAGS.

Most likely the main cause of most the errors is that I'm missing a file or two. And tbh, commenting all the ifdefs is just the same as un-commeting one of the #define lines.

Your danzeff files look okay.

Solve your errors with the missing libpng first. I'd say you don't have the PSP libraries installed, just the toolchain.

No. Wrong way to get the libraries.

If you're not going to use one of Heimdall's pre-built packages, at least read one of the tutorials! Here's one for Ubuntu based on a few threads found here (it can be used for most linux distros):

That doesn't have any libraries in it. It's a script to BUILD the libraries. Please read the tutorial and just follow the directions.
