Got some build problems with the Base Application

[rennurb3000]

Hello Ogre Community!
I started using ogre today and i am totally exited about it,
but i am stuck setting up a new Application

I am using Ubuntu 14.04 64bit and code blocks

I downloaded Ogre 1.9 RC from Sourceforge and was able to build it from source
with cmake as shown in the description

i tried libogre-dev from ubuntu, but for some reason it did not work with cmake (issues with freetype.. i don`t know..)
so i gave building it a try and i got a "seems to be working better" ogre installation

http://www.ogre3d.org/tikiwiki/tiki-ind ... With+CMake

I tried the convienient all in one package wich gave me this output

So i played a little arround and looked through various forums

then i tried the source and header files for linux from
http://www.ogre3d.org/tikiwiki/tiki-ind ... +Framework
where cmake could actually make me a code blocks program

I opened it and tried compiling it...
but i got some compiler errors from OgreFontManager.h and OgreResourceManager.h

Code: Select all

I was more or less expecting some issues with either the CMakeLists and the example framework source files,
but from the Scenemanager.h file??

thanks in advance for your help,

I downloaded Ogre 1.9 RC from Sourceforge and was able to build it from source
with cmake as shown in the description

Ogre 1.9 went from RC to stable a year ago, so that source is a little out of date. The best place to get it from is the official bitbucket repo: https://bitbucket.org/sinbad/ogre

(i've never built ogre in ubuntu (or any linux distro) so i can't help much with that)

tip...
i found out long time ago that for small projects creating the project manualy myself can be faster then fighting cmake scripts/problems...
so you can use the 1.9 updated prebuild dev package for linux and build the project yourself...
btw: i dont see any need for free-type for this project- but i may be wrong somehow....

Freetype is used by the overlay component (for font rendering).

I have a similar issue, did you find how to fix that?

First you have to try building and installing Ogre 1.9 by getting it from here:

https://bitbucket.org/sinbad/ogre/get/v1-9-0.tar.bz2

Ubuntu 14.04 GCC version is gcc-4.8.2. I have successfully built Ogre 1.9 with gcc-4.8.2 so it should be okay there.

The second thing is that those cmake warnings in your first quote are not really a problem -- in the end OGRE was found and the project should work.

Here is how to remove the warning:

reading this again...it sounds like freetype version that ogre was build with is different from the one that is linked/refered by your project...
i think i recall reading something about this minor freetype version change in a mingw related thread...
try to check the code-blocks headers/libs path to see where they lead...
just to make sure...
on your code-blocks project add a "full path" header to the freetype "include dir" that orge was build with...
make sure it is the first on the list( move it up if needed... )
do the same with freetype lib...( full path+move up to be the first on the list... )
