I am trying to automatically set the version in a makefile from the CVS

  • 0

I am trying to automatically set the version in a makefile from the CVS tag. Here is relvant the part of the makefile:

VERSION =$Name:  $

That works ok when I checkout the project. The keyword is replaced by the tag. The problem is that as it is the Makefile does not work unless the keyword is substituted (i.e. the $ signs are gone), so I con not for example compile check the code before committing.
If I escape the $ using $$Name $$, then the checked out version would not compile as it would become $$.

Is there a way to workaround this?

    In GNU make, this kind of construct works:

    COMMAV  := ,v
CVSFILE := $(patsubst %:,,$$RCSfile: Makefile,v $$)
CVSVERS := $(patsubst %:,,$$Revision: 1.130 $$)
CVSDATE := $(patsubst %:,,$$Date: 2012/10/09 22:02:16 $$)
CVSINFO := $(subst $$,,$(subst $(COMMAV),,$(CVSFILE))$(CVSVERS)$(CVSDATE))

    In your case, you are looking for the revision, so I believe the direct solution is:

    VERSION := $(subst $$,,$(patsubst %:,,$$Revision: 1.130 $$))
