How to find out the definition of the variable MAKE
Haven't been using make for a while. But just got a project from a 10 years old compiler using Ubuntu.
I am looking at the makefile and trying to find out which compiler it is using.
${MAKE} is used in the file.
But where can I find out the definition of MAKE.
Thanks
makefile gnu-make

You could simply use both the info and value built-in functions inside your makefile:
$(info MAKE: $(value MAKE))
This will work if MAKE is a recursively expanded variable, which it is by default. Otherwise, if MAKE were a simply expanded variable, you will see the expansion that was done at the moment of evaluating MAKE's definition (i.e., the same as $(MAKE)).
A better approach, which is independent of the flavour of the variable, would be to run make with the option -p and look at the definition of MAKE, e.g.:
make -p | grep 'MAKE ='
You will probably find out that MAKE is defined as:
MAKE = $(MAKE_COMMAND)
and MAKE_COMMAND, which is another variable (this time, a simply expanded one), may be in turn defined as:
MAKE_COMMAND := make

Thank you! Now I understand it better. I have the compiler and linker, the .exe file. I can just use Eclipse to build the project right? The whole purpose to get a "linux" installed on the computer is to run "make" because make is able to interpret the Makefile. And the Eclipse I installed with C/C++ support is able to interpret the Makefile.

Thanks. So it doesn't make sense anymore to install linux (cygwin or WSL) on windows computer just for "make".
