What is the difference between gmake and make?

Question

I am trying to understand the difference between \'gmake\' and \'make\'?

On my linux box they are identical:

% gmake --version
GNU Make 3.81
Copyri         


        

Answer 1

'gmake' refers specifically to GNU make. 'make' refers to the system's default make implementation; on most Linux distros this is GNU make, but on other unixes, it could refer to some other implementation of make, such as BSD make, or the make implementations of various commercial unixes.

The language accepted by GNU make is a superset of the one supported by the traditional make utility.

By using 'gmake' specifically you can use GNU make extensions without worrying about them being misinterpreted by some other make implementation.

Answer 2

On my system no difference (gmake is soft link to make):

-> ls -l $(which gmake make)
lrwxrwxrwx 1 root root      4 Jun  5  2007 /usr/bin/gmake -> make
-rwxr-xr-x 1 root root 168976 Jul 13  2006 /usr/bin/make

gmake stands for GNU make. There're different implementations of make. On Linux machine most probably make will by GNU and to make user's life isier make is soft linked to gmake.

Answer 3

The usual "opposite" of gmake is BSD make, which will tend to be make on BSD systems, unsurprisingly. If you want to see what BSD make is like, on Debian derivatives it's available as apt-get install pmake.

Answer 4

Apparently, GNU make is practically universal now, so there should almost never be a difference.
