Multilanguage development

I would like to develop an application with two languages. Actually, the goal is to generate two differents application, one with a language 开发者_JAVA百科(Java), the other on in another language (C#).

I would like to use makefiles to help me generate one application or the other one, thanks to targets definition.

I don't know where to begin. Have you ever try to develop like this ? Is it possible to use one makefile to call java compiler or c# compiler using different targets ?

Thanks in advance for your help.

Sure, you can use a make file to compile (and link) source files for different languages. There's no limitation. All you need is a compiler (linker) that can be called by a shell / from a command line.

Alternatives: ant can do both Java and C#. If you don't need to build both applications with a single build file, you still can use separate files and write a batch/shell script to call both builders.

Yes it is possible to override a Makefile variable to point to either javac or the .NET compiler.

You will, however, most likely not benefit from this as it is very hard to write a program that is valid in both languages.

You may want to look into http://www.ikvm.net/ which provides a Java emulation environment under .NET, so if you have a Java program it can run under .NET.

There is also the Fantom project, which claims to do that, but I have strong doubts regarding cross-platform support (how can you abstract all side-effects of all APIs?).

But I don't know the project, maybe they do a fine job.

my idea is pretty dumb but i guess you could try this: step 1: make a bat file step 2: make the 2 script files step 3: make it so it executes both of them!

@echo off
start yourfile.script
start yourfile.script

this idea is gonna fail
