It is not open source, so please refer to the copyright notice before using FGb.

In order to use FGb, make sure that OpenMP is supported by your compiler.

1.Installation

You need to download the archive call_FGb5.maclinux.x64.tar.gz that corresponds to your plateform, and to unarchive it:

tar -xvzf call_FGb5.maclinux.x64.tar.gz

According to your platform, you might want to copy all the libraries from call_FGb/nv/maple/C/macosx/ or call_FGb/nv/maple/C/x64/ into a dedicated directory of your choice. For instance, if copied into /usr/local/lib, then no special configuration option is needed for Mathemagix.

2.Configuration

Using configure, if the FGb librairies have not been copied into one of the aforementioned standard location, then you need to specify their path as follows (e.g. for Mac OS X):

./configure --with-fgb="[…]/call_FGb/nv/maple/C/macosx/"

Alternatively, for cmake, you need to specify the path as follows:

cmake ../mmx/mfgb -DFGB_PATH="[…]/call_FGb/nv/maple/C/macosx/"
