Okay, getting a bit late, I've answered my previous question...

However, I'm sure there's a more elegant solution. I added the following to my Jamrules:

actions IdCompile { perl $(TOP)/tools/create_enum_file $(>) > $(<) }

rule IdFile { Depends $(<) : $(>) ; IdCompile $(<) : $(>) ; }

which handles one type of textfiles I have. I then added this to the Jamfile in one of my project's subdirectories:

IdFile TypeID.h : $(SUBDIR)/Setupfiles/TypeID.txt ; IdFile RDBID.h : $(SUBDIR)/Setupfiles/RDBID.txt ;

Writing $(SUBDIR)/Setupfiles/ looks kind of ugly, but I haven't found a more elegant-looking way (especially adding the directory to SEARCH_SOURCE didn't work).

Enno.
