Hello all,

I am trying to install GPAW on my personal machine with Ubuntu OS. After
fixing several issues, I finally encountered the following error which I
cannot think of where it is originating from.

I was wondering if anyone else have seen similar error before? I truly
appreciate any help.

Python 2.7.6 (default, Jun 22 2015, 18:00:18)
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import gpaw
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/alireza/gpaw/gpaw/__init__.py", line 232, in <module>
    from gpaw.aseinterface import GPAW
  File "/home/alireza/gpaw/gpaw/aseinterface.py", line 8, in <module>
    from gpaw.external import PointChargePotential
  File "/home/alireza/gpaw/gpaw/external.py", line 6, in <module>
    import _gpaw
ImportError: /home/alireza/gpaw/gpaw/../build/lib.linux-i686-2.7/_gpaw.so:
undefined symbol: zgttrf_

Regards,
Alireza
