To build and install IMP do: scons prefix=path_to_install install Further documentation and an installation guide can be found at http://salilab.org/imp/doc.html IMP is Copyright 2007-2010 IMP Inventors. The IMP Inventors are Andrej Sali, Ben Webb, Daniel Russel, Keren Lasker, Dina Schneidman, Javier Velazquez-Muriel, Friedrich Foerster, Elina Tjioe, Hao Fan, Seung Joong Kim. IMP is largely available under the GNU Lesser GPL; see the file COPYING.LGPL for the full text of this license. Some IMP modules are available under the GNU GPL (see the file COPYING.GPL). Please refer to the documentation at http://salilab.org/imp/doc.html for more detail. Files under the build directory (even pure Python modules) are built from sources elsewhere within IMP. Do not edit them there - any changes you make will be overwritten! You should also not add any files to these directories, as they will be deleted. The lib directory contains Python modules (both pure Python, in the IMP subdirectory, and C++ extensions, as _IMP_foo.so in the top-level directory) and the IMP C++ libraries (as libimp_foo.so in the top-level directory). Rationale: Windows searches for C++ dynamic libraries in the same directory as C++ Python extensions. The include directory contains all public header files under the IMP subdirectory. Modules are in named subdirectories under that. The swig directory contains all SWIG interface (.i) files used to build the Python interface.
