Where did you download it from? The download from happypuppy was messed up. Try 3dgamers.
And if you have some diskspace try using the --target option.
sh ./armyops200-lnx.bin --target /home/<username>/aao
There will be no questions or prompts, just the files being taken out of the installer script and put into a directory.
cd to that directory you specified, there will be a bunch of files in there. The ones you are interested in are binaries.tar.bz2 and armyops.tar.bz2( the names may not be correct as I'm not at my machine. One will be over 600meg, the other will be around 34meg)
Now uncompress these:
and do the same for the other one.
Then after that is complete you can untar them:
tar xvf armyops.tar
You may have to move the folders/files around a little to suit your prference. The way your directory structure should look after everything is in the correct spot is something like this:
etc, etc, etc
To start the game, open a console and cd to the aao/System folder, and type:
The way I have it setup is /home/hanzerik/armyops/ , But I did not have any problems with the installer.
the two binaries you bunzippped, and untared (server-bin + armyops-bin), should go in aao/System. You can remove the tar files and bz2 files if they are still present.
We do have a Linux support forum for the game at http://forum.americasarmy.com
and there are some posts about this type of error. One of the users, beta testers, moderators may be able to help you if you still have problems.
