You can use target-specific variables: https://www.gnu.org/software/make/manual/html_node/Target_002dspecific.html > I want to describe the build process as simple as possible. > Formulating all rules is no choice.

Targets can have up to 4 or 5 different '%' parts and pattern rules support only 1. What I've done is use variables for the variable parts, with define/endef sections to write thee rules and foreach+call+eval loops to set the variables to each of their possible values. This is a maintainability nightmare, the syntax and semantics are way too hard for me to cope with. > What would be much better are rules automatically build for targets > matching a regular expression.

So my suggestion is that you scan the archives to see how your idea relates to what others have already proposed. > Thanks, Oliver Burghard -- Reinier Post TU Eindhoven _______________________________________________ Help-make mailing list Help-make@gnu.org https://lists.gnu.org/mailman/listinfo/help-make
