Error U1073 When "." Used for Path in Inference Rule

ID: Q51723

The information in this article applies to:

Microsoft NMAKE Utility for MS-DOS, versions 1.01, 1.1, 1.11, 1.12, 1.13, 1.2, 1.3
Microsoft NMAKE Utility for OS/2, versions 1.01, 1.11, 1.12, 1.13, 1.21

NMAKE does not accept a dot (.) to identify the current directory in inference rule paths. When specifying paths for each of the extensions, using the following form

{frompath}.fromextension{topath}.toextension

and using {.} to indicate the current directory for the "topath", causes the following error:

NMAKE : fatal error U1073: don't know how to make 'filename.ext'

To work around this, the current directory for topath must be specified with {}. However, both notations are acceptable when specifying the "frompath".

Later versions of NMAKE accept the dot in the topath.
