C - Makefile error

Question

I am just starting out with C and now I am at the part where I want to learn about Makefiles. I am starting out small but already failing ;)

I have a very simple Makefile which just compiles the main.c to a main.o and then to an executable. But I get an error saying I have a syntax error. I use g++.

The command that i use are:

g++ make Makefile << name of the make file

And the Makefile is set up like this:

main.o: main.c main.h [TAB] g++ -c main.c main: main.o [TAB] g++ main.o -o main

If you're using C, you should use gcc instead of g++ (but it's still wrong for a makefile). — effeffe

I am on windows, i thought g++ is the windows version of gcc. I got it from MinGW — Haagenti

No, both gcc (C Compiler) e g++ (C++ compiler) are part of GCC (GNU Compiler Collection), and they are both in the MinGW porting. — effeffe

To run make on the Makefile (the default name), invoke the make command:

$ make

Don't try to call g++ with the makefile, the compiler knows nothing about makefiles.

EDIT: You say you don't have the make command, in a comment. Then you need to get it. :) There are several versions of make for Windows, here is GNU make (which is common in Linux and other Unix-like environments) ported to Windows.

I am a novic in all of does commands, but my windows doesn't have ( probaly i am not doing it correct ) command make?
