Your best bet would be to examine the command line used by the .vcproj files (in MSVC++ I suspect) and see what differs.

That said, memoverride.cpp will compile without any warnings, but linking still produces this: Linking...

It works perfectly now! Many thanks to Alfred. Is there any way I can get by without /FORCE:MULTIPLE ? The Valve SDK doesn't seem to need it, and doesn't have those errors. It also keeps me from using incremental linking, which is necessary for edit and continue debug sessions, and is just generally much faster. How does the Valve SDK get by without it? -- Jorge "Vino" Rodriguez _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlcoders _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlcoders
