Unresolved External Reference
When Qedit is installed, it changes the CM compilers slightly to redirect file system calls to the Qcompusl routines instead. If you get an “Unresolved External” error message when you compile, it means you are running a “Qedit-compiler” without the Qedit library routines. The most probable cause is that you have just done an MPE update, which removes the Qedit routines from the System SL. The solution is to re-install the Qedit compiler fixes.
