Using paste with Parentheses in Makefile

I'm having problems when using paste with parentheses inside Makefile.

The instruction I'm trying to run is:

paste -d " " <(cat file1) <(cat file2 | grep "pattern")

If I run it from the console it works correctly, however when putting it inside a Makefile the parenthesis causes a syntax error:

/bin/sh: -c: line 0: syntax error near unexpected token `('

Basically what I need is to paste the contents of two (or more) files but filtering some of them with grep.

You have to tell make what shell you want to use. The default one (/bin/sh) does not support the process substitution syntax. Put

SHELL := /bin/bash

somewhere at the top of the Makefile.
