I followed the TUTORIALS at http://ps2dev.org/kb.x?T=927
and it seemed to be success.But I don't know how to compile a file.
I haven't any experience on gcc , cygwin and I haven't used linux or unix like system before,so please tell me how to do it.
thx.

This problem has been solved,please help me with another question at page 2.

[blackdroid]

I suggest reading up on gcc and gnu make.

gcc info

gnu make info

I'd suggest we update the http://ps2dev.org/kb.x?T=927 page so it ends with your two links, as "Getting started" or something similar...

That topic is in "Rubbish" so technically he should not have read it to begin with :)
I guess google brought him to it, ill edit.

I have read the "gcc/g++" info you gived me,and it really take me a long time because my poor English.
I try to compile a hello world program.
I use "cc main.c" in the command line of cygwin,but what I got is a exe file called "a.exe" not elf.

Can u tell me how to get a elf file?

[blackdroid]

first off the ps2gcc has a prefix.. ee-gcc ( for ee binaries) and iop-gcc ( for iop binaries )
when compiling something for ee use ee-gcc, simplest call is ee-gcc file.c -c out.elf

[Chocoboboy]

Faint~It seemed that I haven't ee-gcc and iop-gcc
It says "bash: ee-gcc: command not found"
Is there anything I haven't install?

[blackdroid]

I thought you installed the toolchain by reading the link in your first post.
anyway goto ps2dev.org and check the tools link, there are prebuilt binaries for win32,
alternatively you can use the toolchain.sh script made by ooPo to build the toolchain yourself.

Err... if he used the toolchain, then, the files are under /usr/local/ps2dev/bin, and thus, not under his path. Have to teach him how to set up his PATH variable now (and other environment variables....)

[blackdroid]

if that is all you have in that bin dir your installation is far from complete.
for some bash reference check
http://linux.org.mt/article/terminal

far from complete~I really do all the steps but it give me so many message, I don't know whether it's success or not.~
I will try the toolchain.sh.
But how to use it?Like bat file in MSDOS?

[Chocoboboy]

I have downloaded the prebuilt binaries,and decompression it to my /usr/ps2dev/gcc/ee and /usr/ps2dev/gcc/iop,and then set the path environment variable use "export PATH=$PATH:/usr/ps2dev/gcc/ee/bin:/usr/ps2dev/gcc/iop/bin"
But when I try to use "iop-gcc main.c" to compile the "starsim" sample code,it says

[blackdroid]

you have a Makefile that comes with starsim, it basically contains the info needed for calling gcc in the proper way to compile, use 'make' to invoke, a word of warning though starsim does not compile with ps2sdk since its way outdated, however you can play with the examples in ps2sdk.

Oh...I try to compile hello sample in ps2sdk,but still it can't find some include files.

[MrDark]

You have to modify your Makefile, check it.

[blackdroid]

ee-ggc cant find the include files you want, add -I/path/to/the/includes

I am sorry to trouble you again.But I still can't do it.I don't know why I got so many problems on only compiling a simple hello program.Maybe my computer don't like to do it. :?
This time I use the "-I" to locate my include files,and it seemd my include files have some error.
It gave me many messages,and I can't copy it.I try to use "ee-gcc hello.c -I.... >err.txt" but it doesn't work.I got only a empty text file.
The message on the end is

[mr bob]

are you linking with libkernel.a ?

[Chocoboboy]

What is the libkernel.a ?

[blackdroid]

In the samples dir of ps2sdk you have a hello world program, running make there shows this.

ee-gcc -D_EE -O2 -G0 -Wall -I/usr/local/ps2dev/ps2sdk_r/ee/include -I/usr/local/ps2dev/ps2sdk_r/common/include -I. -c hello.c -o hello.o

ee-gcc -nostartfiles -T/usr/local/ps2dev/ps2sdk_r/ee/startup/linkfile -L/usr/local/ps2dev/ps2sdk_r/ee/lib -o hello.elf /usr/local/ps2dev/ps2sdk_r/ee/startup/crt0.o hello.o -lc -lkernel -lsyscall -lc

Now this is sort of the minimum for compiling something that needs ps2sdk functions.

First line creates and object file of hello, so gcc only need to know where all the includes are wich are all those -I arguments, second line we want to link the program in order to make an executable out of our object file, there we need the libraries, notice the -L in order to tell gcc where to look for the libraries that we want ( all those -l arguments tells gcc to look for functions needed in those libraries ).

now your problem is of the first one, not enough -I statements telling gcc where to find all headers that you need.

I don't have a "crt0.o" in "/usr/local/ps2dev/ps2sdk_r/ee/startup/"
There is a "crt0.s" in that folder,is it that file?

[Chocoboboy]

Yeah~~~I searched my computer for "crt0.o" and copy it to "/usr/local/ps2dev/ps2sdk_r/ee/startup/"
and unbelievable it's ok,I didn't see any error message again~~

Thanks ~~

[evilo]

So now, you are ready to start some coding !!

welcome :)

[Chocoboboy]

I have some problems again , and I can't solve it by myself.
This time I try to build ftpd,When I use "make" to build,it gave me some messages.

[chp]

[blackdroid]

that is one problem with lukasz win32 build, make sure the iop 'as' is before normal 'as' in the path.

[Chocoboboy]

Yes, I am using lukasz win32 build.
I changed it with another one which download from http://www.internalreality.com/
and it's ok now.
I got a ftpd.irx ,so can I execute it on my PS2,and what 's different between .irx and .elf?
And I want to know how to use wincvs.I download and install it with Python 2.2,and
setting cvsroot with ":pserver:anonymous@ps2dev.org:/home/ps2cvs"
and I click login,then type password "anonymous",but after a doxbox show,it back to wincvs and says "***** CVS exited normally with code 0 *****",how can I browser projects with it?

[chp]

[Chocoboboy]

I have run the ftpd,but I can't list any files in mem card.In the readme of ftpd,it says
