[SOLVED] undefined symbol: _ZN2GG13MOD_KEY_RCTRLE

[kroddn]

Hello there,

today I managed to get a running static freeorion, but it crashes when initializing the plugin libGiGiOgrePlugin_OIS.so.

Code: Select all

Loading library libGiGiOgrePlugin_OIS.so
main() caught exception(std::exception): OGRE EXCEPTION(7:InternalErrorException): Could not load dynamic library libGiGiOgrePlugin_OIS.so.  System Error: lib/libGiGiOgrePlugin_OIS.so: undefined symbol: _ZN2GG13MOD_KEY_RCTRLE in DynLib::load at OgreDynLib.cpp (line 80)
*-*-* OGRE Shutdown

Running ldd -u libGiGiOgrePlugin_OIS.so outputs:

I don't know how to solve it. But maybe tzlaine can tell something about it?

Okay, I found out what the problem is. I manually created libGiGiOgrePlugin_OIS.so using this command:

Code: Select all

g++-4.3 -o libGiGiOgrePlugin_OIS.so -pthread -shared src/Ogre/Plugins/OgreGUIInputPlugin.os src/Ogre/Plugins/OISInput.os src/WndEvent.os src/PtRect.os -L/usr/local/lib -L/usr/lib -lboost_signals-gcc43-mt -lboost_system-gcc43-mt -lboost_filesystem-gcc43-mt -lboost_thread-gcc43-mt -lGL -lGLU -lz -lfreetype -ljpeg -lpng -ltiff -lOgreMain -lOIS

So, adding the two sourcefiles src/WndEvent.os src/PtRect.os worked, the symbols are now solved.

What platform is this running on? I haven't seen anything like this on Win32 or Linux32, building the GG tutorials or FO.

The problem already solved when doing a clean build. Sorry, forgot to post that.
