Linux gcc crosscompiling for Apple Darwin Mac

A complete crosscompiling environment for compiling simple gcc programs that can be executed on MacOSX. You compile on Linux and can execute this binary on MacOSX.

Acknowledgment

1. https://github.com/zamaudio/cross-apple This is an almost complete cross compiling Apple toolchain for Debian x86_64 in binary form. It supports ppc, i386 and x86_64 apple targets. (Contains a bug in build-manifest - Version 0 is not allowed.)

Downloading, building and installation of the .deb-packagues

Just check install_run.sh and execute this file...

#!/bin/bash

set -e

# Set manualiy - test uname -m if you are not shure: x64_64 = amd64 and i686 = i383
#arch=i386
arch=amd64

echo "Select $arch as arcitecture"


[...]

echo "Success!"

Testing

hello.c

#include<stdio.h>

int main() {
        printf("Hello World\n");
        return 0;
}

Compile example

• Compile hello-Word example simple:

i686-apple-darwin10-gcc -m64 -std=gnu99  hello.c -o hello_x86-64.app -F/usr/lib/apple/SDKs/MacOSX10.6.sdk/System/Library/Frameworks 

• Move binary to an Apple with MacOSX (Darwin) and call in a Terminal ./hello_x86-64.app
