A question about a list and subprocess.check_call()

[David Aldrich]

Hi

I wonder if someone could help me with this problem please.  I am writing a Python script that builds and tests a C++ program on Linux.  The build options depend on the test, so I have encapsulated the 'make' call in a Python function:

def build(build_options=''):
        if len(build_options):
            subprocess.check_call(['make',build_options])
        else:
            subprocess.check_call('make')

This works fine if I call:

build()
or
build('flagA=true')

The latter gives:

make flagA=true

which is correct.

However, I now want to call make with two flags:

make flagA=true flagB=true

I tried calling:

build('flagA=true flagB=true')

which did indeed result in:

make flagA=true flagB=true

but 'make' ignored the second option. So I think that the list that was passed to subprocess.check_call() was incorrect.

In summary, I want to pass a list to build(), which by default should be empty, and pass that list on to subprocess.check_call() with 'make' as the first element of the list.

Any ideas please?

Best regards

David
