在Python中使用g ++和subprocess(Using g++ and subprocess in Python)

在Python中使用g ++和subprocess(Using g++ and subprocess in Python)

有关如何通过check_output在python中运行命令的任何想法？

g++ -ggdb `pkg-config --cflags opencv` -o output code.cpp `pkg-config --libs opencv`

这是我尝试过没有成功的尝试：

code_cpp = <path to code.cpp> check_output(['g++', '-ggdb', 'pkg-config', '--cflags', 'opencv', '-o', 'output', code_cpp, 'pkg-config', '--libs', 'opencv']) check_output(['g++', '-ggdb', '`', 'pkg-config', '--cflags', 'opencv', '`', '-o', 'output', code_cpp, '`', 'pkg-config', '--libs', 'opencv', '`'])

Any ideas on how to run thus command in python via check_output?

g++ -ggdb `pkg-config --cflags opencv` -o output code.cpp `pkg-config --libs opencv`

This are the attempts I've tried without success:

code_cpp = <path to code.cpp> check_output(['g++', '-ggdb', 'pkg-config', '--cflags', 'opencv', '-o', 'output', code_cpp, 'pkg-config', '--libs', 'opencv']) check_output(['g++', '-ggdb', '`', 'pkg-config', '--cflags', 'opencv', '`', '-o', 'output', code_cpp, '`', 'pkg-config', '--libs', 'opencv', '`'])

最满意答案

由于您使用的是shell功能，因此应调用shell命令：

code_cpp = <path to code.cpp> cmd = 'g++ -ggdb `pkg-config --cflags opencv` -o output {0} `pkg-config --libs opencv`'.format(code_cpp) check_output(['bash','-c',cmd])

Since you are using shell features you should call as shell command:

code_cpp = <path to code.cpp> cmd = 'g++ -ggdb `pkg-config --cflags opencv` -o output {0} `pkg-config --libs opencv`'.format(code_cpp) check_output(['bash','-c',cmd])
