Hi Mathias,
now I understand the reason of the patch. You mean it is convenient for
*uninstalled* build trees. Then you would not have to use LD_LIBRARY_PATH
since CMake links all the binaries in the build tree with rpath, except the
plugins, that would be searched on the patch's given path.
Although I always "make install" my compilings, I decided to try the patch.
However it is not working for me:
~/OSGSVN2/RelWithDebug/bin$ ldd ./osgviewer
linux-vdso.so.1 => (0x00007fff439ff000)
libosgViewer.so.46
=> /home/alberto/OSGSVN2/RelWithDebug/lib/libosgViewer.so.46
(0x00007fa13b444000)
libosgGA.so.46
=> /home/alberto/OSGSVN2/RelWithDebug/lib/libosgGA.so.46 (0x00007fa13b1f0000)
libosgText.so.46
=> /home/alberto/OSGSVN2/RelWithDebug/lib/libosgText.so.46
(0x00007fa13afa4000)
libosgDB.so.46
=> /home/alberto/OSGSVN2/RelWithDebug/lib/libosgDB.so.46 (0x00007fa13ad21000)
libosgUtil.so.46
=> /home/alberto/OSGSVN2/RelWithDebug/lib/libosgUtil.so.46
(0x00007fa13a9a3000)
libosg.so.46 => /home/alberto/OSGSVN2/RelWithDebug/lib/libosg.so.46
(0x00007fa13a541000)
libOpenThreads.so.11
=> /home/alberto/OSGSVN2/RelWithDebug/lib/libOpenThreads.so.11
(0x00007fa13a339000)
(...)
so they are linked to the build tree's libraries, but:
$ ./osgviewer cow.osg
Warning: Could not find plugin to read objects from file "cow.osg".
./osgviewer: No data loaded
Is there an easy way to know which path is OSG looking for to find the
plugins?
Thanks,
Alberto
