PolyBoRi is a joint project of the following institutions
* Mathematisches Forschungsinstitut Oberwolfach (MFO),
* University of Kaiserslautern, Department of Mathematics,
Algebra, Geometry and Computer Algebra Group,
Kaiserslautern, Germany, and
* Fraunhofer Institute for Industrial Mathematics (ITWM),
Department of System Analysis, Prognosis and Control,
With contributions of:
Ket Shcherbakova (nee Kalda), Dominik Stahl
For building the PolyBoRi framework, the following tools and libraries are
* gcc 3.3.0 or newer
* python 2.4 (deprecated) or python 2.5 (recommended)
* scons (v0.96 or later, recommended v0.98 or later)
* the boost library, version 1.33.1 (for python 2.4; deprecated) or
version 1.34.1 (for python 2.5; recommended), version 1.36.1 (for unit tests)
In addition, for running the ipbori command line tool IPython is needed.
Changing to the build directory (where you find this README file), and typing
scons install PREFIX=/prefix/path/ PYINSTALLPREFIX=/python/path/site-packages
should be enough to build and install PolyBoRi.
PREFIX defaults to /usr/local. The standard value from PYINSTALLPREFIX is extracted from the
corresponding python executable (customizable via PYTHON).
There are several installation locations which depend on PREFIX per default,
(e.g. INSTALLDIR and DOCDIR). But those are custumizable, too. See
for more information and default values. There's also an exhaustive 'ipbori'
tutorial in the DOCDIR.
If might also be useful to add some custom setting to the file 'custom.py' in
the build directory, see the following example.
--- custom.py ---
CFLAGS = ""
CCFLAGS = "-g -O3 -ansi --pedantic -Wno-long-long -pg"
CXXFLAGS = "$CCFLAGS -ftemplate-depth-100"
LINKFLAGS=" -Xlinker -export-dynamic -pthread -ldl -pg"
# See also SHCFLAGS, SHCCFLAGS, SHCXXFLAGS, and SHLINKFLAGS
# means that this line is not activated.
#LIBPATH = ["/custom/lib/path1", "/custom/lib/path2"]
#CPPPATH = ["/custom/include/path1", "/custom/include/path2"]
#PBP = "python"
scons devel-install DEVEL-PREFIX=/prefix/for/usr
generates and installs PolyBoRi headers and libraries for developers.
for more infos about possible custom settings.
for making other targets by alias. Valid aliases are
distribute gzipped source tarball
srpm, rpm generate (source)-rpm from data in pkgs/rpm
prepare-debian generate debian/ folder from data in pkgs/debian
deb generate debian package
install install ipbori, documentation, and python iterface
prepare-install build, what install needs
devel-install headers and standalone libraries (without python interface)
prepare-devel build, what devel-install needs
Provided that /prefix/for/executables/bin is in your path, typing
starts an IPython session with the PolyBoRi framework loaded.
Workaround for scons 0.96.x
Please note, that scons 0.96.x is not officially supported anymore, so the
following may be out of date
The currently used CFLAGS/CCFLAGS/CXXFLAGS mechanism was introduced in the 0.97
branch of scons. Using a version from the 0.96 branch CCFLAGS must contain all
flags for the C-compiler, while CXXFLAGS has to carry all flags for CXX.
These settings may be changed using the file custom.py described above. One has
to add the following lines:
CXXFLAGS = "-O3 -std=c++98 -ftemplate-depth-100"
CCFLAGS = "-O3 -std=c99"
Alternatively, one can append the following lines to custom.py:
CXXFLAGS += " " + CCFLAGS
CCFLAGS += " $CFLAGS"
Sun Studio compiler
We recommend to use gcc for compiling PolyBoRi, but compiling with Sun STudio's
C++ in principle possible (albeit untested) with the following settings:
Also CPPPATH, LIBPATH and PYTHON might be adjusted to use library/binaries, which
are compatible with the stlport4 option.
