New subject: Building ALPS on Ubuntu 12.04 - error when building TEBD

22 Jul 2013

      Thank you very much Michele and Matthias! I turned on the ALPS_ENABLE_OPENMP option and I've managed to install without any problems. However, I now have the problem that whenever I try to run one of the tutorial Python scripts, by running:
sudo /home/prentice/Documents/ALPSInstall/bin/alpspython ~/Documents/ALPSInstall/tutorials/dmrg-01-dmrg/spin_one_half.py
I get the error message:
/bin/sh: 1: dmrg: not found
Traceback (most recent call last):
  File "/home/prentice/Documents/ALPSInstall/tutorials/dmrg-01-dmrg/spin_one_half.py", line 51, in <module>
    data = pyalps.loadEigenstateMeasurements(pyalps.getResultFiles(prefix='parm_spin_one_half'))
  File "/home/prentice/Documents/ALPSInstall/lib/pyalps/tools.py", line 397, in getResultFiles
    res=recursiveGlob(dirname, pattern)
  File "/home/prentice/Documents/ALPSInstall/lib/pyalps/tools.py", line 374, in recursiveGlob
    ret += recursiveGlob(os.path.join(dirname, d), pattern)
  File "/home/prentice/Documents/ALPSInstall/lib/pyalps/tools.py", line 374, in recursiveGlob
    ret += recursiveGlob(os.path.join(dirname, d), pattern)
  File "/home/prentice/Documents/ALPSInstall/lib/pyalps/tools.py", line 372, in recursiveGlob
    for d in os.listdir(dirname):
OSError: [Errno 20] Not a directory: './dev/cdrom'

The key problem, I thought, was that dmrg cannot be found, and I'm not sure how to fix this. I've gone back through the archives here and tried editing the .bashrc file, which fixed a similar problem, but didn't work for me. Any ideas how I can fix this? It's a problem with all the tutorials, TEBD, MC, etc.

Thank you again,
Joseph

Hi Joesph,

You will need to add -fopenmp to your Fortran compilation flags

Best regards

Hi all,

Apologies for changing tack, given my previous message about installing on Mac OS X 10.7.5, but I have instead tried installing ALPS on Ubuntu 12.04, following the instructions on the wiki, with admin privileges now. After getting the dependent libraries as described, to compile ALPS I initially used the command:
$ sudo cmake -DALPS_BUILD_FORTRAN=ON -DCMAKE_INSTALL_PREFIX=/home/prentice/Documents/ALPSInstall/ /home/prentice/Documents/ALPS/alps-2.1.1-r6176-src/alps
and this seemed to work well. I then used sudo make and let ALPS build. However, at about 64% in, I got the following message:

Are there any ideas about what can be done with this? There doesn't appear to be a problem with OpenMP, as we have tested it with another simple program, and I have Googled the error too, with no results. I am stumped, and any help would be greatly appreciated. I will attach the CMakeCache.txt file if that is of use.

Thank you very much,
Joseph Prentice
