Protos installation

Protos can be installed in 2 steps. First, you need to install an old release of LHAPDF (5.*.* not 6.*.*) and download the PDF sets that you would like to use. Second, you must proceed to the Protos installation.

LHAPDF 5.9.1 installation

• Download the tarball: ​lhapdf-5.9.1.tar.gz

• Untar the tarball with the command: tar xzf lhapdf5.9.1.tgz. Normally a lhapdf591 folder must be created on your disk.

• Create a folder where the final production of the LHAPDF building will be put: mkdir lhapdf

• Go to lhapdf591 and configure the package: cd lhapdf591; ./configure --nopythext --shared-enabled --static--enabled --prefix=<absolute path of lhapdf> where <absolute path of lhapdf> is the absolute path of lhapdf.

• Launch the building and cross the fingers :-): make; make install

• Configure the environment variables: export LHAPDF=<absolute_path_lhpadf>, export PATH=$PATH:$LHAPDF/bin export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$LHAPDF/lib

• Install PDF sets. This is a example of CTEQ6L1 cd $LHAPDF/shared; lhapdf-getdata CTEQ6L1.LHgrid. The full list of CTEQ can be found here: lhapdf-getdata --list

Protos 2.2 installation

• Download the tarball: ​Protos22.tar.gz

• Untar the tarball
