Indeed, I'm a beginner in "Make", but I read few tutorials and was able to
do what I wanted outside of PG using a simple make file.
Now, when moving to PG, I found the Make structure much more complicated
and didn't know where to add my configuration.
I'm looking only for this file to run in PG (the required functionality is
done already). My code will be a part of the backend, so I want to keep it
You're saying it's going to be a bit tricky to do what I want with make (as
I'm novice in it).. so can you please point out some references I can start
Do you think reposting this in the "novice" mailing list will be a good
