[Bug 775415] Re: Fails to build numpy within a virtual environment

[Michael Ramm]

On natty,

python 2.7.1-0ubuntu5
virtualenv=1.6.1
virtualenvwrapper=2.7.1

python-numpy installs fine.
While trying to install numpy 1.6.0 from source, I run into Bug #780220
 https://bugs.launchpad.net/ubuntu/+source/python-virtualenv/+bug/780220
(same errors as when using pip install numpy within virtualenv)

Title:
  Fails to build numpy within a virtual environment

Status in “python2.7” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: python2.7

  On Ubuntu 10.10, using python2.7: 2.7-6
  virtualenv=1.6.1
  virtualenvwrapper==2.6.3
  numpy-1.5.1

  Trying to install numpy:

  python2.7 setup.py install works well

  But in the virtual environment,
  mkvirtualenv test --no-site-packages -p python2.7
  python2.7 setup.py install
  fails:

  running install
  running build
  running config_cc
  unifing config_cc, config, build_clib, build_ext, build commands --compiler options
  running config_fc
  unifing config_fc, config, build_clib, build_ext, build commands --fcompiler options
  running build_src
  build_src
  building py_modules sources
  building library "npymath" sources
  error: None

  The build process inside the virtual environment works if python2.7 is
  built from source instead of using the packaged version.
