使用python子进程编译c代码时出现错误代码1

Question

I want to compile c code using GCC via Python subprocess. I have installed MinGW gcc for this. When I run the command on the command line, the executable is made, but when I try to do the same via Python subprocess, I get 1 exit code, and hence no executable is made. The command in question :

C:/MinGW/bin/gcc E:/some/folders/main.c

What I'm trying to do

import subprocess

print(subprocess.run('C:/MinGW/bin/gcc E:/some/folders/main.c', shell=True))

Is there something fundamentally wrong here with how I am approaching this ? Thanks

You SHOULDN'T rely exclusively on the "exit code". Instead, you need to:

1. Ensure you're invoking GCC correctly from Python
2. Capture any errors or warnings from your Windows command shell
3. Capture any errors or warnings from GCC

Here are some examples from the Python documentation:

https://docs.python.org/3/library/subprocess.html

 >>> subprocess.run(["ls", "-l"]) # doesn't capture output CompletedProcess(args=['ls', '-l'], returncode=0) >>> subprocess.run("exit 1", shell=True, check=True) Traceback (most recent call last): ... subprocess.CalledProcessError: Command 'exit 1' returned non-zero exit status 1 >>> subprocess.run(["ls", "-l", "/dev/null"], capture_output=True) CompletedProcess(args=['ls', '-l', '/dev/null'], returncode=0, stdout=b'crw-rw-rw- 1 root root 1, 3 Jan 23 16:23 /dev/null\\n', stderr=b'')
