Dear Ganis,

    thank you for your answer.

   I was given one routine by one guy 2 years ago, which worked remotely (bsub) calling other routines. He had given me also a Makefile to link everything together.

  All these routines opend some files stored on CASTOR, filled histograms and saved them in ROOT files again in CASTOR.

  Everything worked up to May 2009. I didn't use that from May up to now. The original Makefile was:


CC=g++
CFLAGS=-Wall -m32 -O2
INCLUDE=-I/usr/local/include/shift
ROOTFLAGS=-lRFIO -O -fPIC -lSpectrum -lRCastor VARIAFLAGS=-L/usr/local/lib -lshift -lnsl -lcrypt -ldl -lm -L/afs/cern.ch/user/n/ntofuser/public/last_soft -lCASTOR2LIB all: analisi.bckg.Am.exe

analisi.bckg.Am.exe: analisi.bckg.Am.c

        $(CC) $(CFLAGS) analisi.bckg.Am.c $(INCLUDE) $(VARIAFLAGS) `root-config --cflags --glibs` $(ROOTFLAGS) -o analisi.bckg.Am.exe 

        @echo '**********************************'
        @echo '*** analisi.bckg.Am.exe produced ***'
        @echo '**********************************'

clean:

        rm analisi.bckg.Am.exe

Where lCASTOR2LIB are libraries specifically made by a man for reading some data in our group.
But now in /usr/local/include/shift on lxplus there's nothing. Therefore I changed /usr/loical/include/shift with /usr/lib

I tried as you suggested

> $ source

> /afs/cern.ch/sw/lcg/external/root/5.17.04/slc4_ia32_gcc34/root/bin/thisroot.sh

> $ export

> LD_LIBRARY_PATH=/afs/cern.ch/sw/lcg/external/castor/2.1.1-9/slc4_ia32_gcc34/usr/lib:$LD_LIBRARY_PATH

and cutting -lRCastor in the line
ROOTFLAGS=-lRFIO -O -fPIC -lSpectrum -lRCastor

In this case after digiting make I obtain no error anymore, but when launching the routines another error shows up Opening CASTOR file
/castor/cern.ch/ntof/2004/fission/stream0/run8203_0.idx.finished in directory 2004/fission. Wait for S TAGER_GET of file. System command is stager_get -S default -M /castor/cern.ch/ntof/2004/fission/stream0/run8203_0.idx.finished -U run8203_0.i dx.finished

If I want to link with the shift libraries, what should I write, please?

Thank you,
best regards,
Francesca Belloni
