在osx上链接到python2.6中的audiolab

问题描述

我一直无法在OS X上使用scikits.audiolab.我尝试了easy_install并从源代码构建，但是两者都给了我相同的错误:

I've been unable to get scikits.audiolab working on OS X. I've tried easy_install and building from source, but both give me the same error:

_sndfile.so是在它描述的位置创建的，所以据我所知，链接到它是一个奇怪的问题.让我感到难过.我打算放弃Audiolab.

_sndfile.so is created in the location it describes, so it's some weird problem linking to it as, far as I can see. Got me stumped. I'm on the point of abandoning audiolab.

我无法使用内置的scipy方法来加载wav，因为它不适用于24位WAV.

I can't use the built in scipy method for loading wavs as it doesn't work with 24-bit WAVs.

推荐答案

Audiolab需要libsndfile.我已经通过MacPorts安装了它，但是默认情况下它仅以x86_64的形式构建.

Audiolab requires libsndfile. I had installed that via MacPorts, but it had built as x86_64 only by default.

删除所有安装并使用+universal标志重新安装libsndfile，将其构建为i386和x86_64.

Deleting all installs and reinstalling libsndfile with the +universal flag built it as i386 and x86_64.

现在，我可以从源代码安装audiolab，并且它可以正确链接. :)

Now I could install audiolab from source and it linked properly. :)
