Hi Jan,
I solved it in the following way:
To the file /etc/ld.so.conf I added the line /usr/local/lib/OpenMesh as root.
Then I did ldconfig as root and then it works.
The Problem is, that the libraries are in the folder /usr/local/lib/OpenMesh.
best regards, Marcel

Hi Jan,
thanks for your quick response.
Before I started , I did call
make install
And the libraries were installed:
masel@masel-x200:/usr/local/lib/OpenMesh$ ls libOpenMeshCore.a libOpenMeshCore.so.2.0 libOpenMeshTools.so libOpenMeshCore.so libOpenMeshTools.a libOpenMeshTools.so.2.0
I tried ldd cube, this is the output:
masel@masel-x200:~/workspace/OpenMesh-2.0.1/src/OpenMesh/Examples/Tutorial01$ ldd cube linux-vdso.so.1 => (0x00007fff0ffd5000) libOpenMeshCore.so.2.0 => not found libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x00007f7bbda63000) libm.so.6 => /lib/libm.so.6 (0x00007f7bbd7df000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00007f7bbd5c8000) libc.so.6 => /lib/libc.so.6 (0x00007f7bbd245000) /lib64/ld-linux-x86-64.so.2 (0x00007f7bbdd9a000)
I tried copying libOpenMeshCore.so.2.0 into the Tutorial01 folder, but this doesn't help.
Did you copy the lib libOpenMeshCore.so as well as the symlink? Is /usr/local/lib/OpenMesh in you path variable?
Regards, Jan
I really don't know what the problem is.

Hi,
if your program links correctly but doesn't start, something is amiss with your library paths.
Try to check the following things:
Check if your program finds the lib directly. For example for the duaalizer the output of ldd is:
ldd Dualizer
linux-vdso.so.1 => (0x00007fffae27c000) libOpenMeshCored.so.2.0 =>
/data1/home1/moebius/projects/OpenFlipper-Free/OpenMesh/build/Build/bin/./../lib/OpenMesh/libOpenMeshCored.so.2.0 (0x00007f441435c000) libOpenMeshToolsd.so.2.0 =>
/data1/home1/moebius/projects/OpenFlipper-Free/OpenMesh/build/Build/bin/./../lib/OpenMesh/libOpenMeshToolsd.so.2.0 (0x00007f4414137000) libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x00007f4413e00000) libm.so.6 => /lib/libm.so.6 (0x00007f4413b7e000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00007f4413967000) libc.so.6 => /lib/libc.so.6 (0x00007f44135e4000) /lib64/ld-linux-x86-64.so.2 (0x00007f441463d000)
If OpenMesh is flagged as not found here, copy the library to your current folder and try again. This time it should be found. Usually if you call
make install
after building OpenMesh, it is installed to /usr/lib and therefore in your library path.
Best, Jan Möbius

Hallo,
ich habe folgendes Problem: Ich möchte die libOpenMeshCore.so.2.0 Bibliothek linken. Beim Kompilieren gibt es auch keinen Fehler, aber dann beim Ausführen schon, s.u.:
masel@masel-x200:~/workspace/OpenMesh-2.0.1/src/OpenMesh/Examples/Tutorial01$ g++ -L/usr/local/lib/OpenMesh cube.cc -o cube -lOpenMeshCore
masel@masel-x200:~/workspace/OpenMesh-2.0.1/src/OpenMesh/Examples/Tutorial01$ ./cube ./cube: error while loading shared libraries: libOpenMeshCore.so.2.0: cannot open shared object file: No such file or directory
Liegt es vielleicht irgendwie an dem symbolischen Link ?!
Es wäre super, wenn jemand dazu eine Idee hätte.
Gruß, Marcel
