最好在基于64位Intel的Mac（Perl / Python用户）上安装MySQL 32位或64位吗？

Question

I have had numerous headaches trying to get the MySQL APIs for Perl and Python working on my 64 bit Macbook Pro (Leopard). I installed the 64 bit version of MySQL, but Googling around now I have the impression that this could be the source of my pain. None of the various blogs and SO answers quite seem to work (for example here on SO )

Could the 64 bit MySQL install be the culprit? Can anyone confirm that they have MySQL access via Perl and/or Python on a 64 bit Mac using 64 bit MySQL? Did you do anything special or face some similar problems?

Answer 1

32-bit and 64-bit libraries don't play nice together. So, it depends whether you're using 32-bit Perl/Python or not.

If you are, you'll need 32-bit MySQL. Chances are your Python, at least, is 32-bit, since both the Apple-shipped Python and the binaries from python.org are 32-bit only. You can build 64-bit Python (or- gasp - a 4-way i386/x86_64/ppc/ppc64 Universal Binary) from source, but unless you really need to work with absolutely huge disk files/amounts of memory (I'm talking multi-gigabyte memory maps, for example), chances are you do not need 64-bit anything right now.

Answer 2

You will need the 32vit vs 64bit of the MySQL client libraries to match the application you're trying to link them with. However, this not prevent you from connecting to a 64-bit install of MySQL server .

In Unix, the MySQL client libraries support multiple versions of themselves lying around; you just have to make sure the application is loading the correct one. This should be true to the Mac.
