Configuration script

[Lise]

Hi!

I'm tying to install Root (physics data analysis program) and the installation guide is saying:

#!/bin/bash

ALIEN_ROOT=/afs/cern.ch/alice/library/afs_volumes/vol01/alien

./configure \
--with-pythia6-uscore=SINGLE \
--enable-alien --with-alien-incdir=${ALIEN_ROOT}/api/include \
--with-alien-libdir=${ALIEN_ROOT}/api/lib

Wath do I have to do? Is this #!/bin/bash -ALIEN_ROOT=/afs/cern.ch/alice/library/afs_volumes/vol01/alien commands or do I have to write this in a file? In that case, what file?

Next is says

#!/bin/bash

make
cd test
make
export LD LIBRARY PATH=$LD_LIBRARY_PATH:.
./stress
./stressHepix

what is #!/bin/bash refering to? Is this commands I have to write in my terminal window?

Thanks!

The #!/bin/bash is known as the shebang line.

What you have posted implies (to me) that you should enter these commands into a script and run it that why. For the 1st one I'd call it config.sh and do this:

# vi config.sh (and enter the commands by copy/paste)
# chmod 700 config.sh (make the script executable)
# ./config.sh > config.log 2>&1 (run the script redirecting the output to a log file)
# more config.log (review the log for errors)

You'd do the same to the 2nd set of commands.

Thanks!
I forgot to mention in the previous post that my Root directory (where I have downloaded my root files) has a file called configure. Do you think that I have to write this lines in this file? But the top line in this file is #! /bin/sh.

Or is the best way to make another script like you said, and when I run this script I can call the configure script from my new script config.sh?

What directory shold I put my new script in? The same directory where I found my configure script? I have to go to the directory where my new script is saved when I want to run it with ./config.sh

DO NOT edit the 'configure' file. That is a script that sets up files used by the 'make' command that's part of the second set of commands. The './configure' in the config.sh file executes it.

Create these files in the same directory that the 'configure' file is in.

config.sh

#!/bin/bash 

ALIEN_ROOT=/afs/cern.ch/alice/library/afs_volumes/vol01/alien 

./configure \ 
--with-pythia6-uscore=SINGLE \ 
--enable-alien --with-alien-incdir=${ALIEN_ROOT}/api/include \ 
--with-alien-libdir=${ALIEN_ROOT}/api/lib

makeit.sh

#!/bin/bash 

make 
cd test 
make 
export LD LIBRARY PATH=$LD_LIBRARY_PATH:. 
./stress 
./stressHepix

Exeucte config.sh, check the log, and then execute makeit.sh (make sure to 1st make it executable as you did with config.sh).

Thank you for your help!

I have tried to do as you explained, but when I run my config script my log file is showing: Xft headers (libxft-devel) MUST be installed.
I have installed libXft-devel wit yum install libXft-devel and the install was ok, but I still miss some files.

What do I have to install to get the Xft headers?
