问题描述

我有这个C程序,至少我认为是(文件:spa.c,spa.h)。有没有什么办法可以不经过额外的参数给Python的跨preTER执行Python的这个脚本(如果没有,会是什么争论呢?)

I have this C program, at least I think it is (files: spa.c, spa.h). Is there any way I can execute this script from Python WITHOUT passing extra arguments to the Python interpreter (if not, what would the arguments be?)

更新:感谢您的答复。该人士$ ​​C $ C可以在 http://www.nrel.gov/midc/找到水疗/#寄存器

Update: Thanks for your replies. The source code can be found at http://www.nrel.gov/midc/spa/#register

(请不要被吓到的网址注册,如果您在填写表格,就可以立即下载文件(没有验证邮件等),我会尝试你的建议,并报告的结果。

(Please do not be scared by the 'register' in the url, if you fill in the form, you can immediately download the files (no validation mails, etc) I will try your suggestions and report back with the results.

更新2 :我编译使用gcc源$ C ​​$ C,但现在它给了我尝试调用(当拒绝权限),运行Python作为根,即使(在Ubuntu 10 IM :10)

Update 2: I compiled the source code using gcc, but now it gives me a permission denied when trying to call(), even when running python as root (im on Ubuntu 10:10).

更新3 [错误8] Exec的格式错误

Update 3 [Errno 8] Exec format error

更新4 确定,我得到了它的工作。用printf程序输出值:

Update 4 Ok, I got it working. Program outputs values using printf:

>>> call(['/path'])

推荐答案

有一个 C脚本没有这样的事情。如果你意味着 C程序您需要编译 spa.c spa.h 进入运行前的可执行文件。

There is no such thing as a C script. If you meant a C program you need to compile spa.c and spa.h into an executable before running it.

如果您使用 GCC 在Linux或Mac OS X:

If you use GCC in Linux or Mac OS X:

$ gcc -Wall spa.c -o spa

会得到你的可执行文件名为温泉

在这之后,你可以运行从你的Python脚本与水疗中心程序:

After that, you can run spa program from your Python script with:

from subprocess import call
call(["./spa", "args", "to", "spa"])
