Hi Dr. Troyer,

          For the clean configuration/installation, do I need to remove dependent libraries (e.g, Python, CMake, etc.) and reinstall them ?

Please try a clean configure and build, and report exactly what you have done. This now looks like a messed up configuration, as ALPS checks at configure time whether sys/systeminfo.h exists.

A note to all who want our help:

Hi Dr. Troyer,

       I was able to fix the issues I previously had. Now when I am trying to build alps, I am getting the message "...fatal error: sys/systeminfo.h: No such file or directory." I have no idea what that file is about - I searched everywhere in my system but was not able to find it. Would you be able to help me out ?

Did you replace the paths with the actual paths on your system?

Hi Dr. Troyer,

          I am stuck at the "Build ALPS section". Listed below are the instructions I followed along with what I actually did:

Download a source package of ALPS: I downloaded alps-2.1.1-r6176-src.tar.gz (I was wondering if downloading alps-2.1.1-r6176-src-with-boost.tar.gz would be better).

Create a build directory and execute cmake giving the path to the alps and to the boost directory: I unzipped the source package and tried using 

 $ cmake -DCMAKE_INSTALL_PREFIX=/path/to/install/directory /path/to/alps/directory

I don't know if I really understood this command line. But when I used it, I the error message "Cmake Error: The source 
directory does not appear to contain Cmakelists.txt"

Thanks,

Niraj

You need to tell us more about where you get stuck if you want to receive help.

I followed the instructions on "Get dependent libraries and tools on Fedora 20" and that was easy to understand and work out. Now I am on "Build ALPS". Either the instructions on "Build ALPS" are not sufficient for a Linux beginner like me or I am not being able to follow them. Please provide me with detailed instructions/guidelines or anything that helps, I will truly appreciate it.
