g++ on MacOSX doesn't work with -arch ppc64
- by Albert
I am trying to build a Universal binary on MacOSX with g++. However, it doesn't really work. I have tried with this simple dummy code:
#include <iostream>
using namespace std;
int main() {
cout << "Hello" << endl;
}
This works fine:
% g++ test.cpp -arch i386 -arch ppc -arch x86_64 -o test
% file test
test: Mach-O universal binary with 3 architectures
test (for architecture i386): Mach-O executable i386
test (for architecture ppc7400): Mach-O executable ppc
test (for architecture x86_64): Mach-O 64-bit executable x86_64
However, this does not:
% g++ test.cpp -arch i386 -arch ppc -arch x86_64 -arch ppc64 -o test

Any idea why that is?
I have installed Xcode 3.2.2 with all SDKs it comes with.
