How to view the commands while making FFmpeg?

Question

When I make ffmpeg, I can see following lines

CC  ffmpeg.o
LD  ffmpeg_g
CP  ffmpeg
STRIP   ffmpeg

What is a quick way to find the commands for CC, LD etc. with as less modification to the Makefile?

Answer 1

This should do it:

$ make V=1

Loot at the common.mak file for the magic that does the silencing.

Answer 2

While its output is not well-formatted, you can use strace on any program to find out what it is executing:

$ strace -f -s 1000 -e execve make 2>&1 | grep execve
execve("/usr/bin/make", ["make"], [/* 39 vars */]) = 0
[pid 22076] execve("/bin/sh", ["/bin/sh", "-c", "printf \"CC\\t%s\\n\" libavdevic
