我試圖將C頭轉換爲使用ctypes和ctypeslib的Python庫。我在OSX 10.6.4（Snow Leopard）上運行Python 2.7。
我正在轉換的頭文件是mcbcio32.h，位於/header/mcbcio32.h 我希望在同一個文件夾中創建一個名爲mcbcio32.xml的xml輸出。提高child_exception Errno 2
我請從ctypeslib夾h2xml.py（其中C頭轉換成包裹xml文件）用下面的命令：
$蟒h2xml.py /header/mcbcio32.h -o mcbcio32.xml -q -c
輸出：
Traceback (most recent call last):

從我可以告訴，三個主要的腳本時，h2xml.py，cparser.py叫，最後subprocess.py。所有這些腳本都是由Python開發人員編寫的，因此我猜測錯誤在於我如何運行發佈命令。
h2xml.py代碼：
"""h2xml - convert C include file(s) into an xml file by running gccxml."""

我已經安裝GCC-XML和ctypeslib被粘貼到： /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ （我的本地Python庫路徑）
