ALPS Application setup and installation documentation is on the separate page " Setup and Installation (Applications)".

Download

The latest version of the ALPS libraries can be downloaded from our download page.

Supported Platforms and Compilers

The ALPS libraries have been tested on the following platforms and compilers:

• Linux with GNU Compiler Collection (g++ version 3.1 and higher), and Intel C++ Compiler (icc version 7.0 and higher)
• MacOS X with GNU compiler (g++ Apple-version 3.1, 3.3 and 4.0)
• IBM AIX with Visual Age C++ (xlC version 6.0) and GNU (g++ version 3.1 and higher) compilers
• Compaq Tru64 UNIX with Compq C++ Compiler (cxx)
• SGI IRIX with MIPSpro C++ Compiler (CC)
• HP-UX with HP C++ Compiler (aCC)
• Windows with Cygwin or coLinux platforms and GNU Compiler Collection (g++ version 3.1 and higher)

See ALPS Tinderbox for the current status of tested platforms and compilers.

Prerequisites

The ALPS libraries requires the source tree of version 1.32 or higher of the Boost C++ library, available at http://www.boost.org. For the IBM compiler and gcc version 3.4 a more recent snapshot or a current CVS checkout is required. Note that it is only necessary to download and untar the Boost sources but no installation is required.

If support for additional features is desired, the following libraries are needed as well:

• An XSLT transformer, such as Xalan of the Apache project or xsltproc of the Gnome libxslt for XML processing. Xalan or xsltproc have to be in the standard path for executables.
• MPI (Message Passing Interface) libraries for message passing support
• HDF5 (Hierarchical Data Format version 5) library for efficient large-scale storage support
• [experimental] Xerces C++ or Expat XML parser for additional XML support
• [experimental] POSIX Thread Library (pthread) for multi-thread support

Installation of Pre-build Packages

GNU/Linux

• testing (etch) and unstable (sid)

There are pre-build Debian packages of the ALPS library in the official Debian package repository. The light version is in the main section. Try

$ sudo apt-get install libalps-light1-dev libalps-sgl1-dev libalps-bin

for minimal installation. To get the full list of packages, check [1].

The full version is in the non-free section. Try

$ sudo apt-get install libalps1-dev libalps-sgl1-dev libalps-bin

for minimal installation. To get the full list of packages, check [2] and [3].

• stable (sarge)

There are no pre-build Debian packages yet...

Installation from the Sources

For easy setup, we have provided a configure script. Just type

$ ./configure

in the top directory of ALPS source tree. The configure script accepts several command-line options. The configure script will automatically look for the directories containing the libraries/source files required (such as boost). If those cannot be found, you need to use further options. See [#Configure_Options#Configure Options] for details. The script will print out a short summary showing which features of ALPS will be available with your current configuration. After configuration, type

$ make $ make install

to build and install all the header files, libraries and tools. This step may take a while. The tools will be created in the tool directory of the ALPS source tree. You can set the path to this directory to use them from all locations of your system. Now the essential part of the ALPS-library installation is completed.

To compile example files, type

$ make examples

To compile and run test suites, type

$ make tests

Configure Options

In this section we explain important options for ALPS configure script. For complete list of options see the output of

$ ./configure --help

Basic Options

For directories, please specify the whole path starting from root.

Optional libraries

Normally configure script will automatically find optional libraries (MPI, HDF5, etc) installed in your system. However, if these libraries are installed in the places different from usual ones, you must specify them by the following options. For directories, please specify the the whole path starting from root.

Compiling User Applications

In order to develop and compile user applications on top of the ALPS libraries, user programs must include ALPS headers and be linked with ALPS libraries. ALPS header files are installed under PREFIX/include, where PREFIX is the path specified by the option to the configure script (see #Configure_Options). ALPS libraries are installed under PREFIX/lib. For example, you can compile and link your program as

$ CC -I/home/ALPS/include -L/home/ALPS/lib -o myprog myprog.C -lalps -lcomm-sgl -lm

For parallel applications using MPI, -lcomm-sgl should be replaced by -lcomm-mpi, and appropriate linker flags for MPI should be appended (e.g. -lmpi). You should link the ALPS libraries exactly in this order. Otherwise you will have an error message from the linker.

Note that during the ALPS setup and installation, a script file named include.mk is also prepared and installed, in which useful macros for make (such as $(CPPFLAGS) and $(LIBS)) are predefined. By using this file, which is installed as PREFIX/share/alps/include.mk, you can write a simple makefile for your application, e.g.

$ cat Makefile include $HOME/ALPS/share/alps/include.mk myprog$nbsp;: myprog.C

       $(CXX) $(CPPFLAGS) $(CXXFLAGS) -o myprog myprog.C $(LDFLAGS) $(LIBS)

myprog_mpi$nbsp;: myprog.C

       $(CXX) $(CPPFLAGS_MPI) $(CXXFLAGS) -o myprog_mpi myprog.C $(LDFLAGS_MPI) $(LIBS_MPI)

(Note that large spaces should be replaced by tabs).

If you want to build your application using autoconf/automake, there is a example package at http://rigarash.info/myprog.tar.gz .

Trouble?
