Build from source for Linux

Written for CEGUI 0.5

---

Works with versions 0.5.x (obsolete)

I happened to notice that this article needed to be written and I was about to install CEGUI from source right now, so I thought I'd document the steps I used, in hopes that they may be useful to somebody.

I'm on ubuntu 6.06 (Dapper)

You need:
- A C++ compiler (g++ in my case)
- Linux Makefile

First you need to download the latest source tarball. I think it's a good idea to keep all the libraries you install from source in a directory, so you can re-compile later with different options if you wish. /home/user/Installs in my case. Move the downloaded tar to your "installs directory" and extract it with:
tar xzf CEGUI-0.5.0b.tar.gz

Enter the CEGUI file:
cd CEGUI-0.5.0/
and type
./configure --help
Scroll up a bit and take a look at the available compile options. Pay special attention to the optional ones, so you can make sure that you get all the features you need. then type
./configure
If everything worked you should get a summary of the build you are going to make. If you don't get the summary, it's probably because you don't have the libraries CEGUI needs to compile. Make sure you have the _DEVELOPMENT_ libraries installed. If you are not happy with the summary, run configure again and use the options from the help section to tweak it.
Here is what I got.

the next part is easy, just type 'make' then 'make install'.
In practice you'll need root privileges to install the files, so with ubuntu:
sudo make install
or in gentoo for example:
su
make install
Hope this helps.

Note: If you're in Gentoo or Saboyan, configure might incorrectly detect your C++ preprocessor as "gcc -E", which will cause Irrlicht to fail. If you need Irrlicht, try: $ CC="g++" ./configure Enjoy!
