I downloaded the precompiled ASSS for Linux and it runs just fine in Ubuntu. However, I am unable to load pymod in order to use modules like fg_wz. When I try to load in pymod when I start ASSS, I get this message:

Code: Show/Hide

What's going wrong here? Do I need to give ASSS a different directory for my Python installation?

I just now installed python2.4 and pymod loads in. However, I can't get fg_wz to load:

Code: Show/Hide

ImportError: /usr/lib/python2.4/lib-dynload/cPickle.so: wrong ELF class: ELFCLASS64

Unrecoverable error (5): Error in loading module '<py> fg_wz'

Is anyone familiar with this error? Does this mean that there is a conflict between the 32-bit ASSS binary and my 64-bit Ubuntu/Python installation?

sounds like it. can you get a 32-bit python installation?

Yeah, I'd say try and get a 32-bit python. Compiling asss to 64-bit would be the other option.

I've done what I can to get 32-bit Python 2.4, but I'm not sure if I'm doing it right. What I've done is installed the 32-bit packages python2.4-minimal and python2.4 with dpkg --force-all and then used getlibs (as described here), but my error has only changed to:

Code: Show/Hide

E <pymod> error loading python module 'fg_wz'

ImportError: /usr/lib/python2.4/lib-dynload/math.so: undefined symbol: PyFPE_jbuf
Unrecoverable error (5): Error in loading module '<py> fg_wz'

It looks like an improvement on the old error message, but it obviously isn't working properly. Is someone more familiar with installing 32-bit packages on 64-bit Ubuntu?

I also tried to compile a 64-bit ASSS, and I've had some success, but I'm getting stuck on the lack of a 64-bit security.so. Does anyone know where I can find one?

Bak · Posted: Sun Jan 04, 2009 4:25 pm Post subject:

send an e-mail to grelminar. he's more accessible than you'd think

for testing just comment out enc_cont in modules.conf and replace it with enc_null to disable encryption

Dr Brain · Posted: Sun Jan 04, 2009 8:19 pm Post subject:

I just started working on converting asss to 64-bit. There are some issues with type sizes. A lot of modules use "unsigned long" for no apparent reason. Maybe grel was worried about systems where an int is 2 bytes?

Dr Brain · Posted: Sun Jan 04, 2009 10:08 pm Post subject:

I've got things compiling, but there are some issues with stack corruption that I'm still investigating.

Dr Brain · Posted: Mon Jan 05, 2009 10:34 pm Post subject:

The 64-bit problems run deep. I've made it a personal project to port asss to amd64, but you're better off looking into the 32-bit python stuff for now.

Dr Brain · Posted: Tue Jan 06, 2009 5:15 pm Post subject:

I'm including the my preliminary changes to make asss run and log players in. I haven't exhaustively tested the system. I'd wager there are a few more bugs lurking around, and would appreciate any feedback. I've also attached a 64-bit security.so.

Be really careful with that pragma pack(1). You should never do that before including system headers, or it could affect the alignment of system structs, which would break a lot of things. All system headers should always come before all asss headers.

pragma pack(1) is evil and I should have never used it. Replacing it with something more sane would be a big effort, though.

Dr Brain · Posted: Wed Jan 07, 2009 10:41 am Post subject:

It's only needed on the packet structs, correct? If so, you could just pragma pack(1) at the top of packets.h, then at the end add a pragma pack(4) or (16), depending on the arch.

That's not the correct command. I think you want "make ../build/pymod.so" instead. Running "make clean" before hand might also be helpful to ensure a complete rebuild, if that's what you're trying to do. The file system.mk has settings for where python is installed.

Yes, limiting the pragma pack to just packets would be a very good idea. pack() (meaning "default") would be better than pack(4), and push/pop would be better than that.

Best of all would be __attribute__((packed)):
http://sig9.com/articles/gcc-packed-structures
http://gcc.gnu.org/onlinedocs/gcc-3.1.1/gcc/Type-Attributes.html
but I think that's only supported by GCC. Does anyone use any other compiler? It might be ok to require GCC...

Dr Brain · Posted: Thu Jan 08, 2009 6:44 am Post subject:

I know a lot of Windows people still use msvc++ to compile their code, so we'll have to use the pack push & pop. I'll start making the changes and verify that they work as expected. I'm also going to look at fixing all of the pointer signedness warnings that started popping up a year ago.
