Orxonox

Posted: **Mon Dec 18, 2006 10:50 pm**

I can only guess where this comes from: I performed a system update, which included upgrading lua from 5.0.3 to 5.1.1...
At first I was quite surprised to see, that configure was downloading lua again - it didn't do that before.

Downgrading is an option, but I'd rather not...

Can anybody give me a hint...
This is the shortened error output from kdevelop

Ok, this problem comes from including headers with lua-5.0 (the version Orxonox is downloading) and linking with the system-wide version installed on your system (5.1.1).

This is why a linker error appears and I think, it might help to remove the LUA-auto-installer.

This can be done in the acinclude.m4, but i think that if you do this you will break the compiling on the tardis and on many other systems.

What system do you have?

Gentoo 2006.1, testing (aka. unstable)

Is there a possibility of including an if branch? Check if any lua version is installed?

I am running some trial and error tests... check back later [done]
no success!

hmm... yeah, I will look into it this evening if I find the time.
The branch condition is a good idea (I had thought I had done it already)

Hmm, I looked into it and here I do not yet have lua-5.1.1 with my Gentoo Linux (just emerge --sync'ed)

And I have spoken with silvan, and he told me, that most probably there is a incompatibility to older versions in 5.1+.

So I will look at the configure-script now...

Thank for the help...

Hmm I looked into it and here i do not yet have lua-5.1.1 with my Gentoo Linux (just emerge --sync'ed)

lua ~arch'ed a few days ago...

There seems to be another (related) problem with lua_setgcthreshhold... The function seems to be removed... I guess I stick with lua-5.0 for the time being.

I need to do some hacking for tomorrow; therefore I will downgrade lua, rebuild kdelibs (sigh), but keep the old versions (quickpkg). So testing should be possible...
