Installing CERNLIB when asis is available

In the following examples, the CERNLIB tree is available via AFS. The procedure is identical for the case when the CERNLIB tree is mounted via NFS  .

Accessing the CERNLIB tree via AFS

Let us assume that we wish to reinstall the CERNLIB software in the /cernlib/cern tree. We first create these directories, and then a subdirectory for the version that we wish to install. We procede as follows:

Setting up the directory tree

mkdir /cernlib/cern
mkdir /cernlib/cern/93d
mkdir /cernlib/cern/93d/bin
mkdir /cernlib/cern/93d/lib
mkdir /cernlib/cern/93d/log
mkdir /cernlib/cern/93d/src
mkdir /cernlib/cern/93d/doc

We now set up a number of links.

Creating links into the AFS  tree

cd /cernlib/cern/93d
ln -s /cern/93d/include include
ln -s /cern/93d/mgr mgr
cd src
ln -s /cern/93d/src/car car
ln -s /cern/93d/src/cmz cmz
ln -s car cra

In fact, only the links for the car and cra directories are required for what follows.

car

The CERNLIB source files in PATCHY card format. This directory also contains the PATCHY cradles (*.cra) used to extract the code.

cmz

The CERNLIB source files in CMZ binary format.

cra

A link to the cra directory.

doc

Documentation on various Monte Carlo generators.

include

include files used when the CERNLIB code is called from C.

We now add the following commands to our profile.

Tailoring the .profile of the cernlib account

PATH=/cern/pro/bin:$PATH; export PATH

export CERN=/cernlib/cern
export CERN_LEVEL=93d
export PLISTA=DEV
. $CERN/$CERN_LEVEL/mgr/plienv.sh

We then reexecute the .profile and switch to the CERN manager directory.

Preparing to build the CERN software

. .profile

cd $CERN/$CERN_LEVEL/mgr

We can now build the complete CERN software by typing make all.  

Building the CERN software

   make -n all

   ...

	makepack -p kerngen
	makepack -s -c kerngen

   ...

	makepack -s -c kernasw
	makepack -l kernlib
	makepack -p cspack
	makepack -s cspack
	makepack -l packlib -c cspack

   ...

	makepack -p isajetd
	rm -r /cernlib/cern/93d/src/cfs/isajetd
	makepack -p pdflibd
	rm -r /cernlib/cern/93d/src/cfs/pdflibd

Various components can be built using the syntax make target. Thus, to build the PAW modules one would type make paw. As the standard Unix make is employed, all the dependancies are known and intermediate components only rebuilt if required.

The following extract from the makefile indicates which components can be rebuilt separately or together.
