Compile problem on Ubuntu 9.04 with Ogre-head [solved+patch]

[boban]

Hi all!

I recently found out about FreeOrion project. I tried to compile it under Ubuntu 9.04. So far I am impressed by the project. Nevertheless, following linux-compile howto on FreeOrion Wiki I stumbled upon two compile errors. They were easy to fix. Two file needed small tweaks: in UI/PagedGeometry/PagedGeometry.cpp call to map was ambigous, in client/human/chmain.cpp call to root->getAvailableRenderers() returns const reference instead of pointer (in rev. 8962 of Ogre3D). Here is svn diff:

I hope this diff will help other compiling FreeOrion on Ubuntu.

I stumbled upon two compile errors. They were easy to fix.

Thanks for the post.

Apparently there have been some changes between Ogre 1.6.1 and the latest version that are causing these errors. I'll add a link to this thread in the wiki.
