[SOLVED]Can't build Ogre3D 1.9 project with CMake on Linux.

Hello! I am an absolute beginner in Ogre 3D. I managed to get it running on Windows, but I am experiencing some problems with Linux(I am using Debian 7.6 Wheezy). I was following this wiki article and got stuck at running the make command. The console shows me these errors:

Code: Select all

I also noticed that CMake gives me a warning when configuring the project:

Code: Select all

CMake Warning (dev) in CMakeLists.txt:
  A logical block opening on the line

    /home/mushmula/Плот/clean_ogre_cmake_project/CMakeLists.txt:29 (if)

  closes on the line

    /home/mushmula/Плот/clean_ogre_cmake_project/CMakeLists.txt:41 (endif)

  with mis-matching arguments.
This warning is for project developers.  Use -Wno-dev to suppress it.

I have no idea why is this happening . I have built and installed Ogre3D 1.9 from the source code. I have installed all of the dependencies. Everything went well without any errors except this. If someone wishes to help me, I will be extremely greatful!

You can ignore that CMake warning, it's not actually a problem. You should be able to just add these includes under the existing includes in BaseApplication.cpp:

Code: Select all

#include <OgreMaterialManager.h>
#include <OgreTextureManager.h>
#include <OgreWindowEventUtilities.h>

error: ‘BLANK’ is not a member of ‘Ogre::StringUtil’ is happening because you are using default branch which is version 1.10. That's totally fine to do, you just need to replace Ogre::StringUtil::BLANK with Ogre::BLANKSTRING

I followed your instructions and now when I run the make command, I get this:

Sorry I meant to say add those includes in BaseApplication.h (not cpp). Add them above the declaration for class BaseApplication (since it derives from Ogre::WindowEventListener). That should fix it

It works now. Thank you so much!
