Use the same makefile for make (Linux) and nmake (Windows)

Question

I have a simple C program (one source file) which I want to compile on Linux and on Windows via make and nmake, respectively. Is there a possibility to accomplish this with

Answer 1

You should look at using CMake for this. With one source file, it should be quite easy. Here is how you could set up a simple project:

cmake_minimum_required(VERSION 3.10)

# set the project name
project(Hello)

# add the executable
add_executable(Hello hello.c)

To build the simple project, you would do the following (this assumes your source and CMakeLists.txt files are in the same directory as the source file hello.c:

mkdir build
cd build
cmake ..
cmake --build .

Answer 2

I just thought of something completely different.

If you stick to your extremely simple Makefile, which, you say, works, and just put the 'standard' variables CC and CFLAGS in your respective environments, say

  export CC=gcc

respectively

  set CC=CL.EXE

and

  export CFLAGS=-o myexecutable

respectively

  set CFLAGS=/out:myexecutable.exe

it might just work.

Be aware, I'm not firm in the exact options to use, you'll have to figure them out yourself. But AFAIK both make variants recognize the same set of flags. You may even set those on the respective command lines (but not in the makefile, since NMAKE uses a different 'ifeq' syntax...)
