How does the make command work?
The makefile is read by the make command, which determines the target file or files that are to be made and then compares the dates and times of the source files to decide which rules need to be invoked to construct the target. Often, other intermediate targets have to be created before the final target can be made.
What is make all command?
‘make all’ simply tells the make tool to build the target ‘all’ in the makefile (usually called ‘ Makefile ‘). You may have a look at such file in order to understand how the source code will be processed. As about the error you are getting, it looks the compile_mg1g1.
What is C make file?

create a file named ‘makefile’ in your homework directory with the identical contents. modify the CLASSES macro so that it has the names of your . java files; run ‘make’, and if all goes well, it should compile all your java source files that need to be re-built.

What is the difference between CMake and make?

While make is you directly writing Makefile for a specific platform that you are working with.
What does make clean do in Linux?
make clean is something you do before recompiling, to make sure you get a clean build and don’t have left-over by-products from previous runs. You can do it after a make install if you want to free some space but keep the source and configuration around. You should not do it before installing.
Is Makefile a shell script?
put a command in a file and it is a shell script. a Makefile however is a very clever bit of scripting (in it’s own language to all extents) that compiles an accompanying set of source code into a program.
