Getting the analysis software

Minimal CLAS software for EG1 analysis

download files from the JLAB CVS repository using the command

type the command below in order to tell CVS to use ssh

setenv CVS_RSH ssh

if you have an account on the JLAB computers you can do

cvs -td :ext:USERNAME@cvs.jlab.org:/group/clas/clas_cvs co packages/fpack

where USERNAME is your JLab username

The above will download packages from JLAB's CVS repository

I only needed the following subdirectories under the "packages" subdirectory to compile the EG1 reader code.

cvs -td :ext:USERNAME@cvs.jlab.org:/group/clas/clas_cvs co packages/fpack
cvs -td :ext:USERNAME@cvs.jlab.org:/group/clas/clas_cvs co packages/cms
cvs -td :ext:USERNAME@cvs.jlab.org:/group/clas/clas_cvs co packages/Makefile

unless the environmental variable OS_NAME is set the Makefile will default to Linux.

Then "cd" to the "packages" subdirectory and type "make"

If you get the error

cc1: error: unrecognized command line option "-fwritable-strings"

then you need to remove this depreceated switch from the file

flags.Linux.mk

near line 45 in the above file change

CFLAGS += $(CLEVEL) -fwritable-strings 

to

CFLAGS += $(CLEVEL) 

Re-type "make" within the "packages subdirectory if you got the above error.

otherwise look in the lib subdirectory and see if you have make the fpack library

packages >ls ../lib/Linux/
libfpack.a

now checkout the EG1 dst library after moving up a subdirectory back to the "CLAS" subdirectory.

cvs -td :ext:USERNAME@cvs.jlab.org:/group/clas/clas_cvs co eg1_dst/dstlib


Tell the makefile where to look for the Makefile scripts

setenv CLAS_CMS /home/tforest/src/CLAS/packages/cms

Tell the dst make file where to put the libraries it is going to built

setenv TOP_DIR /home/tforest/src/CLAS/lib

the files under bosbank depend on ROOT so you need to install ROOT.

EG1 DST reader

The EG1 dsts reader is used to uncompress the EG1 DST data files for analysis. The DST library has at least 3 version now so you must use the correct DST library with your data file.

UNIX software

apt-get install paw apt-get install paw++ apt-get install xemacs

Getting Data files from JLAB

downloading to offsite place

running on JLAB farm

FAQ

fwriteable-strings error

cclose.c -o /home/didbtama/src/CLAS/obj/Linux/fpack/cclose.o
cc1: error: unrecognized command line option "-fwritable-strings" 

To get rid of this error we copied flags.LinuxRH.mk to flags.Ubuntu.mk and changed line

     CFLAGS += $(CLEVEL) -mcpu=pentium -fwritable-strings

to be

CFLAGS += $(CLEVEL) -mcpu=pentium

we also needed to copy the file
link.LinuxRH.mk to link.Ubuntu.mk
