Or allocate from the stack using a char array or alloca(), and align a pointer inside there yourself.

the way i use this option in my sources is safe. Using any other trick give me ugly code (source or binary). hey I added the necessary code to handle it, why does it disappear ?

EDIT:

it seems there is some big changes in gcc/config/mips files... :(((

Well, I'm fairly sure we didn't take it out. Talk to GNU about why it is missing.

hey guys,

I've never done anything like this and have no clue of what I'm actually doing right now, so dont be too harsh on me for not being able to figure this out. ;) I followed a (I guess not up to date) guide that told me the components I had to install to have the pspsdk working in the end. I selected the ones that are mentioned in the pspsdk-20070626 readme as well..

I'm under windows, cygwin.

After installing cygwin I wanted to get the sdk up and running, so what I did was try to execute the script 'toolchain.sh'.

Thats what I get:

For the login script go to C:\cygwin\home\<windows username> and look for a file called ".bashrc", just add the commands to the end.

For ncurses I intalled libncurses-devel, libncurses7 and libncurses8 (I'm not sure if you need them all but it can't hurt, my cygwin folder is only 650mb, but you need more like 1gb free space when compiling).

The new problem is probably due to line endings. You can either open the files in a compatible editor and choose to save them with "unix line endings" or if you don't want to download anything have a look here:

(Sorry this line ending thing did cross my mind in my previous post but I didn't say anything).

At the top of my .bashrc it helpfully says the default copy can be found in /etc/defaults/etc/skel (C:\cygwin\etc\skel), try copying that over to your home dir, then see if you get any errors when starting the cygwin shell before editing the files. Alternatively as a drastic measure you could reinstall the "base-files" package from setup.exe.

When you install cygwin with setup.exe you may need to choose the unix line endings option instead of dos line endings. setup.exe is supposed to cache it's downloads so reinstalling everything shouldn't be too painful... :( I am feeling bad because even though I'm trying to help it seems to be getting worse.

Cubeikon: I have had similar problems with line endings too under cygwin, I have just used an alternate shell ("ash ./toolchain.sh") as a workaround.
--------------
Just noting a couple deficiencies when installing the toolchain fresh under linux today (not sure if anyone else has come across these as of yet) - I figured it was my cygwin that was going odd when trying to make psplinkusb, but...

{additional requirement checks?}
To get psplink bit done (currently step 9 failed without them) libusb-dev and G++ were required.

To actually compile psplinkusb from svn, I had to manually copy pspsysclib.h from the downloaded svn files into /usr/local/pspdev/psp/sdk/include (still not sure why, but my cygwin build updated about a month ago does not have this file in the include dir either?)

Great script ooPo!

I'm installing version 20070626

but fails like:

It should be svn.ps2dev.org. Several of the other scripts have the same problem. Easily fixed.

Its actually been fixed for a while. :)

You fixed it in the library building script, but it's still wrong in the toochain script. I've commited a fix :)

Fine then. Mock my failing memory as I age! :)

Either URL should work just fine...

Jim · Joined: 02 Jul 2005 Posts: 487 Location: Sydney

It works for me too, and obviously for lots of other people else someone would have noticed sooner :)
But e_boris isn't the first person I've seen post that svn.pspdev.org isn't working for them.

On a similar note, today
http://forums.ps2dev.org is working
http://svn.ps2dev.org is working
http://www.ps2dev.org/ isn't working - has been down for about 3 days
That happens periodically. Is this something we know about?

for some reason I have installed cygwin fine, and wget, but it cannot login as anonymous. Which is why I have to download the files myself and do the scripts by hand.

How long does it takes your computer to compile and install the whole PSP cross-compiler environment(using the psptoolchain)?
My laptop was running approximately 27 hours to complete the task.
(The configuration of my laptop: Acer Aspire 5500Z, 1.8G Centrio ,768MB DDR, Windows XP Home Edition with cygwin installed)
Most of the time it is doing "Checking <something...>"
Can anyone tell me some solutions to make the speed up?

Thanks in advanced,

Compiling the psptoolchain from scratch takes about 12 minutes on my development machine, a dual-core 2.4Ghz AMD processor with 2GB of ram.

I've found that cygwin takes much much longer, hours even. A 27 hour compile time isn't surprising, especially given that you have only 768MB of ram.

I don't know if the amount of ram is that big of a difference as I have even less ram then sl862 (512MB) and my compile time is around (if not less) then J.F.'s compile time - up to 2hrs. I have a theory: my Linux system uses available system memory as a disk cache. Linux and Unix systems mostly consist of a lot of small utilities that are chained together to do all the complex tasks. When you compile a application you have a configure script and Makefile that are calling a lot of small programs to do various things ranging from getting the current working directory to modifying text. On a *nix system this is not a issue because of the disk cache - it can just pull the program from memory instead of the hard drive every time it needs to re-run it. Reading it from memory would take a lot less time. These small apps could add up to a big delay.

I notice that when I compile my apps and their dependencies under Windows with MINGW and MSYS that configure scripts and such take a lot longer then on Linux. This could be related, I don't know. I could be totally talking out my ass, this could be minor slowdowns, Windows could have a disk cache too, I could be totally off. I'm taking a stab in the dark. If you want to argue my theory, feel free.

There is one thing you could try. I know my *nix scripts run faster on a native Linux system then on Windows - on the same computer, compiling the same thing. What you could try doing is loading a minimal Linux (like Debian or Ubuntu w/o the GUI) into something like QEMU or VMWare Player 2.0 (you could even connect your PSP directly to the virtual system, though that is a little silly and could be a pain to get working) and do all your compiling from there. Then share out the virtual Linux drive via samba (not the other way as you will mess up your file permissions in Linux) and mount the share inside the host Windows system. This way you still have access to all the files but you are compiling them in a native Linux system. I know visualization can be slower then the real thing, but it might go faster then what you have quoted. I think it's worth a try. Also I wouldn't set the virtual machine to anything over 256mb as you would starve your Windows system (could create swapping problems) and if you just use it for compiling PSP stuff at a console (no GUI), then it shouldn't need more then 256mb much less that much (IMO).

I have found the reason of long time excuting the toolchain. it is due to the anti-virus software. When i close the anti-virus,the time to excuting the toolchain reduce to about 2 hours. Thank you all the same!
