PSP Toolchain on Gentoo Linux

[poedel]

Hellas friends!

I would like to write some C code on my gent00 machine. There are several tutorials.
I choose this one.

Pretty easy I thought, but the toolchain script stopped giving this error msg:

I used this board´s search to find "gentoo psp toolchain" and got several results.
But no1 seemed to have my problems.
The stuff with the script in env.d does not work anyhow, I would place it into ~/.bashrc but the rest sounded logically. I am using Baselayout2 if this should matter.
I rather intend there is missing something in my system. Some special dev- Ebuilds??

There are lots of Gentoo Freaks in here like mk2k. I hope to get help.
Thanks in advance from your German friend Klaus

Oh, E17 ( or E16, at least E )

wget http://www.calebgray.com/psp/development/psptoolchain-20070626.tar.bz2
wget http://www.calebgray.com/psp/development/pspsdk-20070626.tar.bz2

20070626 is the date... It's too old. You should rather checkout the SVN.

svn co svn://svn.ps2dev.org/psp/trunk/psptoolchain
svn co svn://svn.pspdev.org/psp/trunk/psplibraries

I'd place environnements variable in /etc/profile. So, if you use another user, or another shell, there'll be no problems.

I think nothing should be missing in your system, and you're probably not out-of-date :P

Anyway the dependences on Debian are :

build-essential autoconf automake bison flex libncurses5-dev libreadline-dev libusb-dev texinfo libmpfr-dev libgmp3-dev

Hi Kode!
This seems to work. Compiling went through. You gave me a svn command to obtain psplibraries, but this was not mentioned in the wiki. Do I need them, too?
On the same svn method I am currently installing the sdk. You left this step out.
I am a bit confused *G*.

(Yes, it is e17 )

[Kode]

Well, they're not needed, the only library you absolutely must have is the PSPSDK. But you'll probably want to use other libraries, like SDL, zlib, ...

[poedel]

okay, I will probably do compile them when neede *G*
For now it seemes to work.
If my batterie is beeing rechared I will have a try with a new compiled PBP.

Thanx so far!

Later I will have a look for a newbie tut. I think I came along one in here ..

[Kode]

If you want to create game, you can use the oslib mod, still maintained by Sakya : Subversion & Trac | OSLib mod | Assembla
And there are really easy to understand tutorials ( but you can easily guess they were orignally written in French :P ) there: day2 - OldSchool Library ( The first chapter is about the installation on Windows... )

For plugins, and other kind of applications, I guess there are not that much tutorials. You'll easily find how to compile a PRX, how to hook a function, ... but that's all.

[poedel]

Thanx again! I think the libraries are required .. just compiling them.
I rather wanna make some little apps. I never really learned C, but a little c++, basic, pascal, html, php and what came around.
Just adopting code and learning by doing. Future will tell if I get along with it.

[Kode]

You can compile C++ code if you want, using either a C library like the oslib, or a C++ one like JGE++, but you'll often need to use C libraries.

where you are talking about oslib ..
it can't find this lib ..locate doesn't either, though I installed theres psplibraries from svn source.

psp-gcc -I. -I/usr/local/pspdev/psp/sdk/include -G4 -Wall -O2  -D_PSP_FW_VERSION=150   -c -o main.o main.c
main.c:6:25: Fehler: oslib/oslib.h: Datei oder Verzeichnis nicht gefunden

mmh 150? incredible.. this is a little counter someone wrote for me. It is working with 550gen-d2 ..

[Kode]

The oslib isn't in the psplibraries pack : you have to install it manually.

It's normal
It doesn't work only if it's compiled in kernel mode.

I gave the oslib's SVN : Subversion & Trac | OSLib mod | Assembla
Just copy manually oslib.a and the headers in the right folder.

I saw this. I used the internal install.sh ..hope that was correct. Got my laptop here at work. I will try it at 1230 CET ..

edit:
oslib dirs & files are at there position, but make seems to search theme at a wrong position.
psp-config Values are set correctly, environment variables, too.
compiling samples delivered by sdk works.

here an excerpt from the build log:

/home/user/PSP/OSLib_MOD/OSLib_MOD/drawing.c:228: undefined reference to `sceGumMatrixMode'

this structure of folders does not exist at all.
in home is only me, /home/poedel/pspsdk/.. and so on
try to find out where to fix it. Do you know?

Hi!

You're probably using a wrong makefile (you're missing -lpspgum).
If you're using the OSLib MOD check the samples directory.
oslibmod - Revision 46: /trunk/samples

The makefile from the HelloWorld looks like this:

TARGET = helloworld
OBJS = main.o

#To build for custom firmware:
BUILD_PRX = 1
PSP_FW_VERSION=371

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

MYLIBS=
STDLIBS= -losl -lpng -lz \
         -lpsphprm -lpspsdk -lpspctrl -lpspumd -lpsprtc -lpsppower -lpspgu -lpspgum  -lpspaudiolib -lpspaudio -lpsphttp -lpspssl -lpspwlan \
         -lpspnet_adhocmatching -lpspnet_adhoc -lpspnet_adhocctl -lm -ljpeg
LIBS=$(STDLIBS) $(MYLIBS)

LDFLAGS =
EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = Hello World
#PSP_EBOOT_ICON = ICON0.PNG
PSPSDK=$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build.mak

Ciaooo

Thanx Sakya!
I will try and do this this evening.
But remember that someone startet writing this program and compiled it for me as is.
With the same main.c && Makefile it does not work on my machine.
Thus I rather intend something´s wrong with the settings.
Someone (a config or whatever) must have told the compiler to search under /home/user/PSP/ ... for the libraries. IMHO I just should edit this config ..but where

[Kode]

What does psp-config --pspsdk outputs ? If it's in rour home, many things would be at the wrong place. Check $PSPDEV's value too.

poedel@poedel2duo ~ $ psp-config --pspsdk
/usr/local/pspdev/psp/sdk
poedel@poedel2duo ~ $ echo $PSPDEV
/usr/local/pspdev

quite right, isn't it.

[Kode]

Yeah, no problems there. The only problem is that there's an undefined reference, and, in that case, the compiler tell you where the function has been referencend to. It just knows where are the sources.

Didn't it work with Sakya's Makefile ?

[sakya]

Hi!

If the code is written for the "normal" OSLib it's possible that it can be compiled linked with the lib.
I added some reference to OSLib, is there -lpspgum in the makefile you're using?

No this was the path I compiled the lib into (where drawing.c was located), you don't need that path.

Ciaooo
Sakya

[poedel]

wow! unbelievable! it worked!
With the libs settings of the "hello world" makefile it works.
Thanks, friend!
Now I can start testing C
Can I test the eboot directly on the laptop anyhow, or do I always have to test it on the psp?

[Kode]

You have to run the EBOOT on your PSP. You might get a code which compiles on both system ( with libraries like the SDL ), but nothing more. There's psplink which allows to run a PRX from your computer. If you want to use it, add BUILD_PRX = 1 in your makefile, and then run usbhostfs_pc ( root privileges are required for this on my system ), and pspsh. On your PSP, run the oe eboot ( installed $PSPDEV/psplink/psp/oe/ ). Finally, in a terminal run pspsh and type your prx's path. Notice you can run commands like

pspsh -e "my.prx"

[poedel]

astonishing ..

okay, Then I will keep on copying the eboot to the psp. If I know how the code behaves I will get a feeling for what will happen on the screen. Previewing will be needed less then, I suppose.
Thanx anyway!
