sysconfig.get_config_var('srcdir') seems to return the current working directory rather than a directory related to the source directory.

For example (starting from the repository root)--

$ mkdir foo
$ cd foo
$ ../python.exe 
Python 3.3.0b1 (default:5d43154d68a8, Jul  8 2012, 18:23:20) 
[GCC 4.2.1 Compatible Apple Clang 3.1 (tags/Apple/clang-318.0.58)] on darwin
>>> import sysconfig
>>> sysconfig.get_config_vars('srcdir')
['/.../cpython/foo']
>>> import sys
>>> sys.executable
'/.../cpython/foo/../python.exe'

This may be the cause or related to bpo-15300: "test directory doubly-nested running tests with -j/--multiprocess".

Looks like a duplicate; I can’t search right now (try sysconfig + build).

[cjerdonek]

I searched a little before. There is bpo-12141, "sysconfig.get_config_vars('srcdir') fails in specific cases," but that issue is closed.

In the comments there, Antoine seems to be describing the bug I describe here, but I'm not sure an issue was filed:

http://bugs.python.org/issue12141#msg136493

I think bpo-15364 is a duplicate of this.

It should be fixed now. Can you check again.

[cjerdonek]

It seems to be fixed now. Thanks.
