dependency generation

[Torsten Mohr]

Hi,

in a large project i use automatic dependency generation.
This works fine and as expected.

To generate the dependencies i use a perl script that
gets (along with some other parameters) the include path
on the command line and outputs a dependency file.

The command line gets very long and i work on Windows 2000.
At the moment everything works.

To shorten the command line i'd like to write the include
paths into a file and then call that perl script that
generates the dependencies with that file as a parameter.

This could be done easily by writing the include path
into a file before calling that perl script.

But:  I'd like to generate that file only ONCE, not every
time the perl script is executed.

Is there a way to formulate a rule to do that?


Best regards,
Torsten.
