| === WHIZARD & gfortran === | === WHIZARD & gfortran === |
| Installations of WHIZARD 2 and its prerequisite gcc 4.5.2 can be found in ''/opt/gcc-4.5.2'' and ''/opt/whizard'' on the amd64 machines. | |
| |
| == gfortran == | Under Natty, WHIZARD is globally installed in /usr/local and available in the default path by simply running "whizard". |
| As gfortran supports the subset of FORTRAN 2003 required by WHIZARD 2 properly only starting with version 4.5 (and Ubuntu currently distributes 4.4.3), a installation of gcc 4.5.2 (also containing c / c++ / etc.) is located in ''/opt/gcc-4.5.2''. In order to use it, the binary and library search paths must be augmented with the proper directories. This can be done automatically by sourcing a setup script ''source /opt/gcc-4.5.2/setup.sh''. Please be aware that this will substitute __all__ gcc compilers with their 4.5.2 versions in the running shell. | |

| == WHIZARD 2 == | |
| Installations of WHIZARD 2 can be found in ''/opt/whizard/whizard-[version]''. Versions numbers ''whizard-2.0.x-pre-mmddyy'' refer to unreleased SVN snapshots. In order to use the installation, the library and binary search paths must be updated - this can be achieved by sourcing ''source /opt/whizard/whizard-[version]/setup.sh''. Note that, as WHIZARD requires the gfortran compiler at runtime, this setup script also configures the paths to the necessary gcc installation (see above). After this step, the whizard binary and the various O'Mega executables are avaiable in the running shell. The WHIZARD and O'Mega manuals can be found in ''/opt/whizard/whizard-[version]/share/doc''. | |
| | |
| Note that this installation of WHIZARD is compiled without LHApdf support; for parton distributions, you have to rely on the builtin PDF sets (consult the WHIZARD manual for more documentation). If you need LHApdf support, you have to compile LHApdf and WHIZARD yourself (which should be trivial as Matthew has been kind enough to install O'Caml and friends ;) ). | |
| | |
| The most current version can be found in ''/opt/whizard/whizard-2.0.5-pre-012611/''. | |
