Qt5 and Ogre3D

Nihilivin

Hi all!

I know that many threads are already talking about that, but I still didn't find any solution... And I know i'm close to it.

I made a very simple Qt Project to run an Ogre3D rendered frame through a Qt Widget. I made all I could, and the only thing that misses is including Boost, and I don't know how to do that in the .pro file.

My error messages are:
@C:\OgreSDK\boost\boost\system\error_code.hpp:214: erreur : undefined reference to boost::system::generic_category()' C:\OgreSDK\boost\boost\system\error_code.hpp:216: erreur : undefined reference to boost::system::system_category()'@

According to my researches, those errors are dues to a non-linked dll... If someone is able to give me some help, I'll be grateful :)

Best regards

Hi and welcome to devnet,

You need to link to the boost system library, add

@LIBS += -lboost_system@

To your pro file. If it complains it can't be found add

@LIBS += -LC:/OgreSDK/path/to/boost/lib_files@

Hope it helps

It seems to include Libs correctly, there is no error message added... But no one less too... It seems that nothing had changed

SGaist

Strange, did you try doing a complete rebuild ?

Nihilivin

I tried a complete rebuild, with the line you specified : @LIBS += -LC:\OgreSDK\boost\lib@
Nothing new.
I'm blocked on that step since 4 months... And I'm sure once this problem solved, Ogre3D should work correctly... It's a little bit frustrating!

You should use forward slashes for all platforms when using Qt.

Can you check the various boost libraries to see if any contains that missing symbol ?

Hello, and sorry of being so long to answer.
I already did that research, and this function is described in "libboost_system-mgw47-mt-d-1_51.a".

I also replaced all my \ by / as you suggested. Still no changes.... I think I gonna kill myself TT

SGaist

Looks like static library, try to link to it directly

Nihilivin

And how can I do that?

Edit : I'll Google it... But I think I have already searched about that and I didn't understand.... But let's retry
