我创建了一个简单的hello world程序,并尝试使用gcc执行生成的C程序,但无论我做什么,我都会获得大量未定义的引用.
在SO上有许多类似的问题,但他们都说安装python-dev(或它的一些变体)或添加标志来链接和加载库,但我已经尝试了这两个选项.
hello.py
def main():
print "Hello,World!"
if __name__ == "__main__":
main()
我跑：
cython --embed hello.py
然后我尝试在表单中运行gcc的一些变体：
gcc -I /usr/include/python2.7/ -L /usr/lib/python2.7 -lpython2.7 hello.c -o hello
我要么找不到“Python.h”文件,要么出现以下错误信息：

我已经安装了python-dev(及其变体).用“python2.7 / header_file”替换头文件仍会导致未定义的引用.我正在运行Ubuntu Linux 3.13.0-73-generic.
如何使用gcc编译我的cython代码？
谢谢.

find /usr/include / -name Python.h输出：
/usr/include/python2.7/Python.h
/usr/include/python3.4m/Python.h
find /usr/lib * -name libpython2.7.so输出：

我正在构建一个64位系统,gcc目标是64位( – build = x86_64-linux-gnu –host = x86_64-linux-gnu –target = x86_64-linux-gnu)
最佳答案
