Ogre Version

[libolt]

While I am moving my code to Ogre 1.11 I still need compatability with 1.10. Does ogre have a preprocessor macro that defines the version number?

[dark_sylinc]

See these macros in OgreMain/include/OgrePrerequisites.h

Code: Select all

#define OGRE_VERSION_MAJOR
#define OGRE_VERSION_MINOR
#define OGRE_VERSION_PATCH
#define OGRE_VERSION_SUFFIX
#define OGRE_VERSION_NAME
#define OGRE_VERSION

Cheers

Code: Select all

#if (OGRE_VERSION < ((1 << 16) | (11 << 8) | 0))
// 1.10
# else
// 1.11
#endif

probably we should also provide a OGRE_VERSION_LESS macro with ogre...

As far as I understand, OGRE_VERSION_MAJOR, _MINOR and _PATCH are now (1.12) only available in OgreBuildSettings.h? Or at least removed from Prerequisites.h. Is this from 1.12.0 or already in 1.11.5?

Reason: I am fiddling with FindOgre.cmake in CEGUI v0-8.

you shouldnt have to:

but to answer your question, its in OgreBuildSettings.h since 1.11.5 already.

The problem is that find_package(Ogre) fails because it greps Prerequisites.h, not OgreBuildSettings.h for the major, minor and patch. Anyway, thanks for your help. I'll try to submit a backward compatible fix (to cegui) : )

[paroj]

with the linked patch, it should use find_package(OGRE) which does not grep anything, but uses the new cmake findconfig infrastructure.
Only if this fails it falls back to find_package(Ogre).

Maybe you are on a case insensitive FS and the above logic fails. Then the fix is to rename the FindOgre.cmake script to FindOldOgre.cmake and change the according line to find_package(OldOgre)

the new cmake findconfig infrastructure

ah ok, I'll check this. Thanks : )
