To install MathMore from SVN (trunk revision) do the following (you need also mathcore), since the built library will contain both: > svn co https://root.cern.ch/svn/root/trunk/mathcore mathcore > svn co https://root.cern.ch/svn/root/trunk/mathmore mathmore > cd mathmore run the setup script which uses autoconf and automake to generate the makefile. Be sure to have a not too old version of autoconf/automake installed in your system > build/setup.sh configure with the configure script. To use MathMore outside ROOT, you need to specify a location of GSL. A tar file of GSL with the functions needed by MathMore is available in the mathmore/src directory. If you don't have a version of GSL in your system you can build the one distributed with mathmore using configure and make. > ./configure --with-gsl=$gsl_dir > make To build the test do: > make check and to run them (like testRootFinder) do: > test/testRootFinder If you install from the tar file, you can skip the setup part and run directly configure.
