So far as I can tell, it builds for me without problem. Thanks for your reply. There is one file though, Gear.cpp, which adds a further dependency on SimGear. Gear.cpp is part of the SHARED_SOURCES, which are used to build both the standalone SimGear program and the FlightGear library. Gear.cpp includes: #include simgear/scene/material/mat.hxx which in turn includes: #include osg/ref_ptr #include osg/StateSet If I'm correct, this inclusion of SimGear related files is necessary to get a gear-related drag coefficient, from the scenery. In addition, there is reference to OSG code in mat.hxx, so it seems very logical to me the OSG must be linked to yasim-test. I think you may have a library pollution issue; maybe a local change to one of your SimGear libraries is suddenly pulling in OSG code where before it stood alone? I have considered that, but I've removed every trace of any SimGear and OSG header and library files from my install path, and any reinstalled everything from scratch several times. In addition, I have several copies of the FlightGear and SimGear and FlightGear source tree on my computer. A developer version and a clean version. Even the clean version shows the problem.

Andy Andy, is there any chance you are looking at the Pre-OSG (i.e. PLIB based) branch of FlightGear?

Andy Oh, wait a second: I now see you are talking about the header (.hpp) file, whereas I was referring to the (.cpp) source file, Gear.cpp. You are right that the former (the hpp) contains (only) the SGmaterial reference. The latter, the Gear.cpp source file is the one containing the additional SimGear include, as shown in the url to the cvs log in my previous mail.

Nonetheless, from a build just completed: $ ldd ./yasim libdl.so.2 = /lib/libdl.so.2 (0x2ac79e774000) libstdc++.so.6 = /usr/lib/libstdc++.so.6 (0x2ac79e878000) libm.so.6 = /lib/libm.so.6 (0x2ac79ea78000) libgcc_s.so.1 = /lib/libgcc_s.so.1 (0x2ac79ebf9000) libc.so.6 = /lib/libc.so.6 (0x2ac79ed07000) /lib64/ld-linux-x86-64.so.2 (0x2ac79e657000) Those extra SimGear libraries don't require anything from OSG, except perhaps the compile-time headers. Are you doing anything fancy like building SimGear as a shared library?

To find out which libraries are qctually required I'd ususally use 'nm' to get an idea which function is implemented in the respective libs. Personally I'd vote for inclusion only of those libraries where inclusion is unavoidable While you're at it, you could probably add '-losgText' in src/Main/ in order to link the 'fgfs' binary on FreeBSD without manual interaction ;-) Cheers, Martin. -- Unix _IS_ user friendly - it's just selective about who its friends are ! -- - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
