思路是先將py轉換為c代碼,然后編譯c為so文件,所以要安裝以下內容:
python 安裝:cython
pip install cython
linux 安裝:python-devel,gcc
yum install python-develyum install gcc
初步編譯
新建Test.py文件,內容如下
class test: def __init__(self): print('init') def say(self): print ('hello')
新建setup.py,內容如下
from distutils.core import setupfrom Cython.Build import cythonizesetup(ext_modules = cythonize(["Test.py"]))
在bash中執行
python setup.py build_ext
運行后會生成build文件夾,如下
現在so文件就可以像普通py文件一樣導入了
集成編譯
做了以下內容:
1.文件夾編譯
2.刪除編譯出的.c文件
3.刪除編譯的temp文件夾
將需要編譯的目錄和setup.py放在同一層級,執行python setup.py,so文件在build目錄下
setup.py代碼如下:
