Before anyone suggests posting this to netscape.public.mozilla.builds, I already did, but got no replies. So, if anyone can help it would be much appreciated. Thanks. I'm trying to build mozilla from source for the first time using the 0.9.2 tarball. W2K-SP2 + VC++6-SP5 D:\mozilla>nmake /f client.mak build_all Microsoft (R) Program Maintenance Utility Version 6.00.8168.0 Copyright (C) Microsoft Corp 1988-1998. All rights reserved. client.mak(453) : fatal error U1023: syntax error in expression Stop. Huh? Line 453 in client.mak is a comment: #//------------------------------------------------------------------------ # Verify that MOZ_SRC is set correctly #//------------------------------------------------------------------------ # Check to see if it is set at all <<==== Line 453 !if "$(MOZ_SRC)"=="" MOZ_SRC = $(MAKEDIR)\.. !endif Anyone know what's going on? Can nmake not count? Regards, Parish
