Compilation error on OgreEvenListeners.h

For help with general CEGUI usage:
- Questions about the usage of CEGUI and its features, if not explained in the documentation.
- Problems with the CMAKE configuration or problems occuring during the build process/compilation.
- Errors or unexpected behaviour.

Hi :)

I may run a couple more tests in relation to this, thought I'll just waffle on here for a bit anyway :lol:

Due to some double-dependencies between Ogre and CEGUI, the usual sequence of things is this:

    Configure, build and install CEGUI
    Configure, build and install Ogre (this will detect you have CEGUI and build the Ogre CEGUI renderer module)
    Re-configure, build and install CEGUI (this will then detect the Ogre CEGUI renderer module and use it in the samples.


Now, from source it is Ogre and not CEGUI that installs the CEGUI-OGRE.pc file. But in the pre-packaged versions, this file comes with CEGUI and not Ogre - which is the first point where things can start to get hairy.

Another issue is that by default, the default local .pc file install path of "/usr/local/lib/pkgconfig" is not added to the environment variable PKG_CONFIG_PATH used by pkg-config - so if you have the pre-packaged CEGUI still installed, this will get picked up instead of the 'real' one you just installed via the source. This wrong version of the file basically points to the pre-built libs, so you'll end up with errors there too. So it's essential to remove the prebuilt version if you're going the source route. And add the appropriate dir to the search path used by pkg-config.

If you do go the source route for CEGUI then SVN code is recommended since it has almost the required fixes for OIS support required by newer Ogre versions (almost because depending on the OIS you have, there are still minor changes to make - see above posts).

Anyway, at least life is not dull :)

CE.

Ok, this post details my experiences with getting Ogre and CEGUI working on a machine running Kubuntu 7.1 (Gutsy Gibbon). I'd like to mention that this is not my 'usual' system - which is Gentoo Linux (amd64), and it's a system that's not normally used for development, though this post does not detail installing the build tools.

First of all i removed libogre-dev and libcegui-mk2-dev packages that I previously had installed via aptitude.

At this point I'd like to note that you'll probably already have most or all of the required libs already installed if you use your system for development, as mentioned I did not previously use this system for development, so that's why I mention the packages I installed.

I downloaded and unpacked the latest stables for Ogre and CEGUI, which are 1.4.6 and 0.5.0b respectively.

I installed the following packages that were either required to build CEGUI, or that I decided I'd like :)

Code: Select all

xorg-dev
libgl1-mesa-dev
libglu1-mesa-dev
libdevil-dev
libtiff-dev
libois-dev


Somewhere around this point I discovered a bug in the config scripts, so had to make the following change. This relates to the DevIL image loading lib, so if you've not got that installed, then you could skip this :)

Now, we need to backport this release to support OIS. So for that you need the following patch. Note this patch was assembled by hand from stuff I got from the web svn for CEGUI. If you place it in ./dev/CEGUI-0.5.0/ you should appy it with the -p2 option.

now I configured, built and installed CEGUI.

For Ogre, I installed the following stuff via aptitude:

Code: Select all

libzzip-dev
libfreeimage-dev
nvidia-cg-toolkit


Now I configured, built and installed Ogre.

At this point you can test the Ogre samples that use CEGUI if you like :)

Once this was all working, I went back and redid the configure, build and install of CEGUI.

One final step that was required was to copy the plugins.cfg file from ./dev/ogrenew/Samples/Common/bin to ./dev/CEGUI-0.5.0/Samples/bin

Now the CEGUI samples will run under Ogre.

Some final thoughts are that the PKG_CONFIG_PATH stuff I waffled about earlier did not seem to matter. And don't forget to do ldconfig so that the library cache is updated.

I hope this helps :)

CE.

I have checked my configuration and I have done an error in my makefile, So now, it works correctly.

I've tried your patch and it works perfectly, and I've tried svn too (never tried on linux).

Thanks a lot for your help,
