MacOSX上的g ++不支持-arch ppc64 [英] g++ on MacOSX doesn't work with -arch ppc64

问题描述

我想用g ++在MacOSX上构建一个Universal二进制文件。但是，它并不真正起作用。我试过了这个简单的虚拟代码：

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;
}

这很好：

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

然而，这并不是：

However, this does not:

% g++ test.cpp -arch i386 -arch ppc -arch x86_64 -arch ppc64 -o test
In file included from test.cpp:1:
/usr/include/c++/4.2.1/iostream:44:28: error: bits/c++config.h: No such file or directory

/usr/include/c++/4.2.1/ext/atomicity.h:40:30: error: bits/atomic_word.h: No such file or directory
...

任何想法这是为什么？

我在MacOSX 10.6上。我已经安装了Xcode 3.2.2及其附带的所有SDK。 GCC 4.2是默认设置。 GCC 4.0产生了一些不同的错误，虽然表现类似。

I am on MacOSX 10.6. I have installed Xcode 3.2.2 with all SDKs it comes with. GCC 4.2 is the default. GCC 4.0 produces some different errors, though behaves similar.

推荐答案

ppc64支持在Snow Leopard中被丢弃。如果您构建并链接到Mac OS X 10.5 SDK，则仍然可以使用ppc64。

ppc64 support was dropped in Snow Leopard. You can still use ppc64 if you build and link against the Mac OS X 10.5 SDK.

请在命令行尝试以下命令：

Try the following command at the command line:

g++ test.cpp -arch i386 -arch ppc -arch x86_64 -arch ppc64 -mmacosx-version-min=10.5 -isysroot/Developer/SDKs/MacOSX10.5.sdk -DMACOSX_DEPLOYMENT_TARGET=10.5 -o test

或者对于10.4 SDK使用：

Or for the 10.4 SDK use:

g++-4.0 test.cpp -arch i386 -arch ppc -arch x86_64 -arch ppc64 -mmacosx-version-min=10.4 -isysroot/Developer/SDKs/MacOSX10.4u.sdk -DMACOSX_DEPLOYMENT_TARGET=10.4 -o test

请注意，如果您想使用10.4 SDK，你将不得不使用gcc 4.0（或g ++ 4.0）。 Apple的GCC 4.2不支持10.4 SDK。

Note, if you want to use the 10.4 SDK, you will have to use gcc 4.0 (or g++4.0 ). Apple's GCC 4.2 doesn't support the 10.4 SDK.
