Hi All, If I build boost using bjam (no problems there) and set in .bashrc: export DYLD_LIBRARY_PATH="$DYLD_LIBRARY_PATH:${BOOST_ROOT}/stage/lib" Things seem to work OK when when calling applications from the command line in a terminal. However if I invoke the application e.g. x.app from the Finder the boost dynamic libraries are not found. If I run for example, otool -D /Users/andrewmaclean/Code/GeneralLibraries/boost_1_44_0/stage/lib/libboost_date_time.dylib /Users/andrewmaclean/Code/GeneralLibraries/boost_1_44_0/stage/lib/libboost_date_time.dylib: libboost_date_time.dylib Clearly no absolute path is set. It seems to me that Finder is ignoring the DYLD_LIBRARY_PATH variable, I even changed it to DYLD_FALLBACK_LIBRARY_PATH to see if it would make any difference. So the only solution I have is to install boost into the default system libraries, where it works perfectly. Now comes the interesting question. If I build VTK then the absolute paths are put into the dynamic libraries. So something in CMake/gcc actually adds these paths into the dynamic libraries. Why doesn't bjam do this? Is there a parameter I am missing? Rgeards Andrew -- ___________________________________________ Andrew J. P.
