Hi all, sorry to send a second email, but don't worry, a colleague has helped me out. We've fixed it by writing the full path to the dmrg (or other applications) file for everything other than TEBD. For TEBD, we had to edit the tools.py file, in the runTEBD function, inserting the full path to the tebd file. Thanks for all your help, Joseph Prentice ________________________________________ From: comp-phys-alps-users-bounces@lists.phys.ethz.ch [comp-phys-alps-users-bounces@lists.phys.ethz.ch] on behalf of comp-phys-alps-users-request@lists.phys.ethz.ch [comp-phys-alps-users-request@lists.phys.ethz.ch] Sent: 22 July 2013 11:00 To: comp-phys-alps-users@lists.phys.ethz.ch Subject: Comp-phys-alps-users Digest, Vol 88, Issue 6 Send Comp-phys-alps-users mailing list submissions to comp-phys-alps-users@lists.phys.ethz.ch To subscribe or unsubscribe via the World Wide Web, visit https://lists.phys.ethz.ch/listinfo/comp-phys-alps-users or, via email, send a message with subject or body 'help' to comp-phys-alps-users-request@lists.phys.ethz.ch You can reach the person managing the list at comp-phys-alps-users-owner@lists.phys.ethz.ch When replying, please edit your Subject line so it is more specific than "Re: Contents of Comp-phys-alps-users digest..."

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: Scanning dependencies of target tebd [ 62%] Building Fortran object applications/dmrg/tebd/CMakeFiles/tebd.dir/core/GlobalData.f90.o [ 62%] Building Fortran object applications/dmrg/tebd/CMakeFiles/tebd.dir/core/LinearOps.f90.o [ 62%] Building Fortran object applications/dmrg/tebd/CMakeFiles/tebd.dir/core/HamiOps.f90.o [ 63%] Building Fortran object applications/dmrg/tebd/CMakeFiles/tebd.dir/core/StateOps.f90.o [ 63%] Building Fortran object applications/dmrg/tebd/CMakeFiles/tebd.dir/core/LocalOps.f90.o [ 63%] Building Fortran object applications/dmrg/tebd/CMakeFiles/tebd.dir/core/ObOps.f90.o [ 63%] Building Fortran object applications/dmrg/tebd/CMakeFiles/tebd.dir/core/Hdf5Interface.f90.o [ 64%] Building Fortran object applications/dmrg/tebd/CMakeFiles/tebd.dir/core/PropOps.f90.o [ 64%] Building Fortran object applications/dmrg/tebd/CMakeFiles/tebd.dir/tebd.f90.o Linking Fortran executable tebd CMakeFiles/tebd.dir/tebd.f90.o: In function `MAIN__': tebd.f90:(.text+0x8b0): undefined reference to `omp_get_num_procs_' tebd.f90:(.text+0x9ab): undefined reference to `omp_set_num_threads_' collect2: ld returned 1 exit status make[2]: *** [applications/dmrg/tebd/tebd] Error 1 make[1]: *** [applications/dmrg/tebd/CMakeFiles/tebd.dir/all] Error 2 make: *** [all] Error 2

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 <TEBD Fail Ubuntu CMakeCache.txt.gz>
