I found a line like this in the file:
numpy/distutils/fcompiler/__init__.py
I changed the -2 to 2, but it didn't change anything. In fact, this line wasn't called.
The fct set_verbosity() is called only once, with the value of 0. The default value set at import. If I change that to 2 or -2, it do not change anything.
I think that the problem is related to the exec_command as you told. It seam it call it in a way that don't take the stdout/stderr set in Python. So I can't redirect it. The problem is that is use os.system() and we can't redirect its stdout/stderr.
What about replacing the os.system call to subprocess.Popen? This would allow us to catch the stdout/stderr. We use this call in Theano and it is compatible with python 2.4.

Hi,
NumPy 1.8 removed the private NumPy interface numpy.distutils.__config__. So a Theano user make a PR to make Theano use the official interface:
numpy.distutils.system_info.get_info("blas_opt")
But this output many stuff to the output. I can silence part of it by silencing warnings, but I'm not able to silence this output:

I tried to redirect the stdout and stderr, but it don't work. I looked into NumPy code and I don't see a way to change that from a library that use NumPy.
Is there a way to access to silence that output?
Is there a new place of the old interface: numpy.distutils.__config__ that I can reuse? It don't need to be a public interface.
Looks like the problem is in numpy/distutils/exec_command.py and numpy/distutils/log.py. In particular, it looks like a logging problem and I'd guess it may be connected to the debug logs. Also, looks like numpy.distutils.log inherits from distutils.log, which may be obsolete. You might get some control of the log with an environment variable, but the function itself looks largely undocumented. That said, it should probably be printing to stderror when run from the command line.
In numpy/distutils/__init__.py line 886 try changing log.set_verbosity(-2) to log.set_verbosity(2)
