When I compile two files with the dmc command line, I get:
...
link Qstring+bits,,,user32+kernel32/noi;
OPTLINK (R) for Win32  Release 7.50B1
Copyright (C) Digital Mars 1989 - 2001  All Rights Reserved

bits.obj(bits)
 Error 42: Symbol Undefined ??0String@@QAE@I@Z (syscall
String::String(unsigned
))

--- errorlevel 1

Both files compile fine.  How do I find where the undefined symbol is being used within the source file?  I can't find it in the map files.

Grep will tell you which .obj file it is in.
