How to specify additional dependencies of files

[Daniel Kraft]

Hi!

In my automake Makefile I need a way to generate testfiles when the 
corresponding test program is compiled.  I have something like:

check_PROGRAMS = test
test_SOURCES = test.cpp

But I need a file created by make (i.e., a command executed which 
creates it) when test is compiled.  Is there a way to specify this?

test: myfile

Doesn't work, as test has other dependencies as well (generated by 
automake).

Yours,
Daniel Kraft
