vivvasu is on a distinguished road

Hi, we have a C application built on Darwin 8.4 and having problems linking against a third party dylib built on Darwin 9.8. We suspect Darwin libraries are not backward compatible, i.e. cannot link to 9.x libs on 8.4. The linker throws the 'load command 8 unknown cmd field' message

/usr/bin/ld: ../../..//libconsub3.dylib load command 8 unknown cmd field
/usr/bin/ld: warning can't open dynamic library: libconsub3.dylib referenced

In short, can dynamic libraries built on 9.x be linked/used with applications built on 8.x? If yes, then what gcc compiler flags should be used to link the 8.x application with the 9.x libraries?

Any help in this regard will be greatly appreciated.

QUOTE Thanks
