Current PS2SDK fails to compile.

In attempting to compile the current PS2SDK sources I get the following results:

Code: Select all

iop-gcc  -O2 -G0 -c  -I/usr/local/ps2dev/ps2sdk_src/iop/kernel/include -I/usr/local/ps2dev/ps2sdk_src/common/include -Iinclude -Wall -fno-builtin-printf -fno-builtin-memcpy -std=c99 src/ps2snd.c -o obj/ps2snd.o

make: *** [all-iop] Error 2
Since the first error message refers to an unrecognized option of iop-gcc, I assume that the rest simply result from the failure to use that option. But why that error in the first place ? Is this some option that requires a newer version of iop-gcc than v2.8.1, which I use ?

If so, then what about the problem that v3.2.2 produces IRXs that simply don't work properly ?
Is there a newer version available which fixes that ?

Gah! That would be my code, sorry. I'll add a hack into the makefile to check for the IOP compiler version now.

I use iop-gcc 3.2.2, and it works fine. I don't have any problems with IRXs that "simply don't work properly". All the IRXs i've compiled with it work fine...

EDIT: "Fixed" in rev 1226. It'll skip compiling the ps2snd module with old iop-gcc's now. If you want to use ps2snd you'll have to upgrade your toolchain, sorry. ;)

Good, that should at least solve the immediate problems.

Sorry I can't say the same...
I am not exactly alone in having this problem (NB: huge understatement), so I hope someone with insight into the iop-gcc sources can fix this sometime in the future. There is definitely something wrong with the optimizations inherent to -O2 (and higher).

Using iop-gcc 3.2.2 many projects will work right only if compiled with all optimizations turned off, resulting in hugely bloated code. Yet the same projects work fine when compiled by iop-gcc 2.8.1 with -O2.

At first I thought this was merely due to different optimization defaults in the two versions, and that the affected projects could be fixed by using different options. Unfortunately I never found settings that give the same results as iop-gcc 2.8.1 does.

Ok, I can easily switch back and forth between the two compilers, and I already do switch between several different PS2SDK versions, for experiments, so doing this is not a problem in itself.

The real problem here its that PS2SDK as a whole has thus become limited to being compiled with a version of iop-gcc that is suspect (at least to me, and many others). This is not good !!!

However, a possible workaround for this would be to compile two versions of PS2SDK. One using v3.2.2 and one using v2.8.1 of iop-gcc, and then copying the fully functional ps2snd module from the former to the latter. That should fix the problem for my own purposes anyway, though I strongly recommend rewriting the code so that either compiler can handle it.

Hrm....
I'm definitely using 3.2.2, and I'm definitely using -O2 optimisations.
All the IRXs in ps2sdk compile and run fine.
All other IRXs that I've attempted to use compile and run fine.
Several other people use 3.2.2 and get working output too.

I remember that there were some problems with iop-gcc 3.2.2 back in the early days, but afaik that's all been fixed now.
If you're using an old version of iop-gcc, try using the latest from svn://svn.ps2dev.org/ps2/trunk/ps2toolchain

I'd like to see some real examples of the latest iop-gcc 3.2.2 failing to compile something, or giving broken output. It'd be useful to have the code of the IRX, the build setup, and the broken IRX output.

Remember, it's possible to build a broken toolchain using working patches, so check that out first. (Last time I checked, GCC & Binutils hate being compiled with optimisations)

Ok, if you need an example take a look at ps2ftpd. Compile it with the newer iop and watch it crash. Just load up ps2link then load ps2ftpd.irx and try to transfer a file to mc and you'll get an exception. No problems with the older iop here.

I get this when compiling with iop-3.2.2

Sorry, If I haven't been of much help, I'm not a gcc guy.

Here is where the discusion was earlier about an issue with the newer IOP compiler and ps2ftpd.

This is the exception error you'll get when loading ps2ftpd module through ps2link and then transfering a file to memory card.
