Can anyone spot why this is ignoring the EE_LIBS line? It's definitely ignoring because I entered some made up name and it doesn't flag an error.

I'm trying to add the standard C lib so I can use rand() on the second tutorial.

EE_LIBS is part of the makefile template files (makefile.eeglobal, etc),and you aren't using them, you are just writing all your own rules... so of course it won't work.

furthermore, you should check/use the makefile samples from the SDK, those ones are quite old ;)

[Kojima]

It won't compile with the sdk makefiles. I don't get it, I've looked through the ps2 sdk samples and not a single line (that I saw) actually invokes EE_LIBS etc.

How much work would it be to add lib support to the above makefile?

[Kojima]

You just made a very powerful enemy my friend.


:)

Thanks.

[evilo]

perfect :)

anyway, I hope to play your ps2 pong very soon now !

[Kojima]

You could play it now if I had any ftp space. My isp despite being one of the biggest companies in the uk(BT) are too cheap to give any for free.

I'll try looking for a free provider though.

[Kojima]

Man, I'm not having any luck with this makefile. If it's not too much trouble, could someone modify the one i posted up above to load libs please? I just don't know what to do.

[Kojima]

I managed it. I don't know how, perhaps voodoo magic, but its working now.

-Edit- Spoke too soon, although it works fine for C, my attempts to convert to C++ have almost worked but not quite,
it now fails, complaining about a missing strlen def. I've done the Extern "C" thing to all my sources but it's not working.

Here's the error,

[Kojima]

Fixed it, i had to order the libs, moving stdc to the second lib like so,

-lc -lstdc++ -lgcc -lm -lsyscall

in case anyone else runs into this problem.

-edit- well spoke too soon again, it compiles run but ps2link just says 'could not execute file host:demo20a.elf"
I opened up irlink and it seems to transfer about 30% of the file before aborting.
Any ideas why?

here's the current make file,

[evilo]

kojima,

please :

1st - don't use irlink, but prefer ps2client

2dn - don't reuse that makefile, and prefer a new one based on the SDK samples

check one of mine (from my smw port)

[Kojima]

I am using Ps2Client, I just used irlink to monitor how much of the file was transfered before it failed. IrLink doesn't even work anyway, aside from the transfer monitor.

I did try to make a new make file based on the samples, but it wouldn't compile saying there was no rule for the .o files, when there clearly was.

But shouldn't my one above work? It compiles fine, links fine, just doesn't run? All I did was change from C to C++, as I did with my pong game, and pong runs fine in C++.

No ideas at all how i could fix my one up? I'm learning just by tinkering with the sample makefiles and I understand how it works now, mostly(At least as far as getting something to compile and link goes)
but my knowledge isn't great enough to figure out why a perfectly compiled and link app fails to run.

In the words of Lennon. Help!

:)

[evilo]

with the new makefile rules, you must rename the .s to .S :)

[Kojima]

There are rules for that in eeglobal too as far as I can see.

I've just tried again, took my pong makefile, ee global and tried to make a new one based on both for the new app, and still it complains 'no rule to make target '/g2.o'

HEre's the main makefile

[Kojima]

Well I've managed to get the new makefile compiling and linking just fine. But as before the final elf refuses to run on the ps2.

[evilo]

Seems that uint64 is not recognized..

be sure that g2.c include tamtypes.h

[Kojima]

I fixed that problem, please check my edited post above, i got the makefile working(The new one) but the resulting elf fails to run still.

Makes. No. Sense.

edit- changed -Tlinkfile to -T$(PS2SDK)/ee/startup/linkfile and now it runs, but immediately after running it throws a EE exception "TLB store exception"

So it appears to be the linkfile is what's causing problems.

[Kojima]

FIXED! Thanks for all your help e.

turns out the exception was an unrelated mistake in my code, so the linkfile change did fix it afterall. So anyone who uses the tutorials as a base like i have, be sure to change linkfiles if you switch to C++.

Anyway expect LikeAllegro very soon, a old skool 2d library with per pixel fx like lighting etc :)

[evilo]

Good that you fixed your issue !

concerning LikeAllegro, does it have something to do with Allegro ??

I hope you'll use gsKit as a base instead of the libdream tutorial .... libdream is great to see how the GS is working, but just lacks good performances :)

[Kojima]

Yeah, kind of like Allegro, Bitmaps etc, but won't be as fleshed out or based on allegro's code.

I will probably use gsKit for my second lib, I'm still learning so I think I'll use the tutorials mini-lib for now.
