Warnings in any compile that uses Ogre

Hi, i'm getting a couple of warnings for every file that includes ogre.h. The warnings are these:

In file included from /usr/include/OGRE/OgreEntity.h:37,
                 from /usr/include/OGRE/Ogre.h:41,
                 from data/suspensionData.cpp:12:
/usr/include/OGRE/OgreSharedPtr.h: In member function `void 
   Ogre::SharedPtr<T>::destroy() [with T = Ogre::Mesh]':
/usr/include/OGRE/OgreSharedPtr.h:140:   instantiated from `void Ogre::SharedPtr<T>::release() [with T = Ogre::Mesh]'
/usr/include/OGRE/OgreSharedPtr.h:88:   instantiated from `Ogre::SharedPtr<T>::~SharedPtr() [with T = Ogre::Mesh]'
/usr/include/OGRE/OgreMesh.h:53:   instantiated from here
/usr/include/OGRE/OgreSharedPtr.h:149: warning: possible problem detected in 
   invocation of delete operator:
/usr/include/OGRE/OgreSharedPtr.h:149: warning: invalid use of undefined type `
   struct Ogre::Mesh'
/usr/include/OGRE/OgrePrerequisites.h:260: warning: forward declaration of `
   struct Ogre::Mesh'
/usr/include/OGRE/OgreSharedPtr.h:149: note: neither the destructor nor the 
   class-specific operator delete will be called, even if they are declared 
   when the class is defined.

Am i doing something wrong, or is this normal? If more info is needed, tell me what to post and i'll post it.

BTW data/suspensionData.cpp:12: is just a #include "Ogre.h"
I'm using Ogre v1rc1. I had no warnings with Ogre v0.15.2

I'm having 'note's on my GCC with SharedPtr...

Hil,

Please, somebody can say how to only deactivate those messages of warning in LInux? They are very annoying when you must compile much

Thanks in advance

Yeah this is a known issue and I really must find a perminent solution to it.

Please respond to this post or put something in the developer's section when you do change this. It might break pyogre, since SharedPtr is a sensitive area for pyogre.

Installing gcc 3.4.x gets rid of the warning too.

I'm inclined to think this is a false warning since it disappears on later gcc's and I can't for the life of me understand what it doesn't like (we've tried a number of workarounds that should have worked and none did).

I can swear I got it on both 3.4.x and 3.3.x. I'll check tonight.

yup I got 3.4.4 and stil notes about sharedptr

Post by **_mental_** » Tue Feb 15, 2005 5:48 am

Ok I was completely wrong. 3.4.4 doesn't throw up that warning on my system.

Ok something weird is definitely going on with both 3.3 & 3.4 (even though 3.4 doesn't complain). I'll continue looking into this tomorrow.

(bump)

Anyone sorted this out yet?

Post by **_mental_** » Fri Feb 18, 2005 5:41 am

I'm still working on it. I haven't had much time recently due to work and family constraints but I really need to get this sorted by the weekend.

Post by **_mental_** » Tue Feb 22, 2005 4:36 pm

Ok this has been fixed in the v1-0 branch of CVS.

Great work _mental_, going to test it in a min
