Spring RTS Engine

Hello,

I was trying to join a multiplayer game, but everytime I tried, i got kicked out with a dialog box saying my mod versions mismach, but they dont. I even asked one guy to do a md5sum on the file, checksums matched, but he can join and i can't, how come?

I tried two versions of spring, one from ubuntu repository, and one i compiled from svn, both with the same result.
The mod is Balanced annihilation 5.8, haven't tried others
OS: ubuntu 7.10

Content error: Your mod differs from the host's mod. This may be caused by a missing archive, a corrupted download, or there may even be
2 different versions in circulation. Make sure you and the host
have installed the chosen mod and it's dependencies and
consider redownloading the mod.

This is undoubtebly your problem. You have an edited file, or you and the host have a different file.

Make sure you are up to date.

Edit: Otherwise, it may be that you are running linux. I didn't read your whole post. I am not sure of linux's capabilities with Spring.

I even asked one guy to do a md5sum on the file, checksums matched, but he can join and i can't, how come?

Pretty sure they are the same file and Linux should work fine.

What lobby are you using? I don't think it should affect it but...

I'm using springlobby-0.0.1.0696

Does the mod load when you just run spring directly? (without lobby)

Yep, everything's just fine except online play

Done some source hacking and found the problem..

It appears that the function:
unsigned int CArchiveScanner::GetModChecksum(const string& root)

Generates checksum for the mod file AND it's dependencies

according to the source comment
/** Get checksum of all required archives depending on selected mod. */
it does the job, but the server part doesn't

[ARCHIVE9]
{
Name=BA58.sd7;
Path=/home/walmis/.spring/mods/;
Modified=1193587195;
Checksum=1314280966;
Replaced=;
NumMaps=0;
[MOD]
{
Name=Balanced Annihilation V5.8;
Description=Moooooo!;
ModType=1;
NumDependencies=3;
Depend0=springcontent.sdz;
Depend1=otacontent.sdz;
Depend2=tatextures.sdz;
NumReplaces=0;
}
}


The server sends a checksum for BA58.sd7 only, and therefore i get a mismatch.

But now the big question, why do I get this problem and others don't?

We use the current version, try a reinstall of the version off of this site, and redownload the mods you need, etc. The SVN version contains a lot of experimental features.

the thing is, i tried both. Anyways i got it fixed.
