scikits audiolab安裝錯誤

Question

我正在使用mint Linux Mint 13 maya（linux 3.2.0-23-generic x86-64）
我正在嘗試安裝scikits.audiolab來執行一些音頻信號處理。我已經下載了所有先決條件，即（python-dev python-numpy python-setuptools libsndfile-dev）。 我已經site.cfg作爲

[sndfile] 
include_dirs = /usr/include/ 
library_dirs = /usr/lib/x86_64-linux-gnu/ 

我得到當我做 '$定位asound在' 我得到

我如何設置以下錯誤

SndfileInfo: 
    FOUND: 
libraries = ['sndfile'] 
library_dirs = ['/usr/lib/x86_64-linux-gnu/'] 
include_dirs = ['/usr/include/'] 

    AlsaInfo: 
libraries asound not found in /usr/local/lib 
libraries asound not found in /usr/lib 
scikits/audiolab/soundio/setup.py:21: UserWarning: Alsa not found - alsa backend not build 
warnings.warn("Alsa not found - alsa backend not build") 
CoreAudioInfo: 
scikits/audiolab/soundio/setup.py:31: UserWarning: CoreAudio not found - CoreAudio backend not build 
warnings.warn("CoreAudio not found - CoreAudio backend not build") 

。 py找到這些庫。有什麼我失蹤？ 我見過http://forum.ubuntu-fr.org/viewtopic.php?pid=3748397和scikits.audiolab on Ubuntu Oneiric - ImportError: No module named _sndfile

這是造成這麼多frustation

UPDATE

在我的電腦的這個錯誤之一是取消了對完全未安裝scikits-AUDIOLAB的和ALSA，然後更新apt-get在重新安裝alsa和scikits-audiolab之前。

Answer 1

下面在Ubuntu上爲我做了alsa音頻後端工作。

作爲指向http://cournape.github.io/audiolab/installing.html#installation-from-sources，安裝alsa標頭：

$ sudo apt-get install libasound2-dev 

在源目錄或者，

/path-to/scikits.audiolab-0.11.0/

，或者，如果使用點（源默認下載到/ tmp）

/tmp/pip-build/scikits.audiolab

創建site.cfg文件，除了[sndfile]部分創建一個[ALSA]部分：

[sndfile] 
include_dirs = /usr/include 
library_dirs = /usr/lib/x86_64-linux-gnu/ 
[alsa] 
include_dirs = /usr/include/alsa 
library_dirs = /usr/lib/x86_64-linux-gnu 

使用定位或apt-文件列表中找到，其中asoundlib.h（include_dirs）和libasound .so（library_dirs）位於您的系統中。

好了，在完成所有這些並嘗試重新安裝之後，它仍然無法工作。我一直得到同樣的令人沮喪的消息：

SndfileInfo: 
    FOUND: 
    libraries = ['sndfile'] 
    library_dirs = ['/usr/lib/x86_64-linux-gnu'] 
    include_dirs = ['/usr/include'] 

AlsaInfo: 
    alsa not found 
scikits/audiolab/soundio/setup.py:21: UserWarning: Alsa not found - alsa backend not build 
    warnings.warn("Alsa not found - alsa backend not build") 

所以，我不得不使用這個技巧。打開文件/path-to/scikits.audiolab-0.11.0/scikits/audiolab/soundio/setup.py和替換

14 alsa_info = info_factory('alsa', ['asound'], ['alsa/asoundlib.h'], 
15       classname='AlsaInfo')() 

與

alsa_info = info_factory('alsa', ['asound'], ['asoundlib.h'], 
         classname='AlsaInfo')() 

如果這樣做能爲更多的人，我們可以請求David Cournapeau（scikits.audiolab作者）製作這個補丁。
