我可以建立在Mac OS库的32位和64位架构？ [英] Can I build both 32-bit and 64-bit architectures of a library on Mac OS?

问题描述

我需要在Mac OS X上建立一个库（Ipopt），并从两个不同的程序（Python的＆安培; Matlab的）使用它。然而，一个程序是32位，而另一个是64位。我一定要建立两种架构的两个独立的库，然后相应地设置路径每个程序？或者，我可以建立在同一个库文件（S）两种架构，程序会选择正确的架构加载？如果可以，那么如何？

I need to build a library (Ipopt) on Mac OS X and use it from two different programs (Python & Matlab). However, one program is 32-bit and the other is 64-bit. Do I have to build two separate libraries of the two architectures then set the path accordingly for each program? Or can I build both architectures in the same library file(s) and the program will select the correct architecture to load? If I can, then how?

谢谢！

推荐答案

您可以建立两种架构，并结合成一个单一的二进制文件。要做到这一点的工具是脂。

You can build both architectures and combine them into a single binary. The tool to do this is lipo.

例如，如果你已经建立libpopt作为一个32位的库，并把它放在的lib / ，再次建造它作为一个64位的库，并放置在 lib64的/ ，然后命令结合这两种可能是：

For example, if you had built libpopt as a 32 bit library and placed it in lib/, and built it again as a 64 bit library and placed that in lib64/, then the command to combine these two could be:

lipo lib/libpopt.a lib64/libpopt.a -create -output libUniversal/libpopt.a
