HELLO EVERYBODY. I AM USING SUSE LINUX VERSION 11.0. I HAVE CREATED setup.sh FILE AS FOLLOWS:

export CPPMAKEOPT="-MM"
export CPPCOMPILE="g++ -c "
export CPPLINK="g++ "
export CPPCOMPILED="g++ -g -c "
export CPPLINKD="g++ -g "
export FORTRAN77="gfortran"
export ARCOMMAND="ar -rs"
export WCPPLIB=$HOME
export WCPPLIBOBJ=$WCPPLIB/wcpplib
export CERNLIB=/usr/lib
export SPACKLIB="-lpacklib -lnsl"
export CFLIBSERV="-lg2c"
export USE_HBOOK=1
export USE_SRANLUX=1
export USE_CPP_SRANLUX=1

export CLHEP_INCL=$HOME/CLHEP/include
if ( $?LD_LIBRARY_PATH ) then
export LD_LIBRARY_PATH=/home/hecrrc/CLHEP/lib:$LD_LIBRARY_PATH
else
export LD_LIBRARY_PATH=home/hecrrc/CLHEP/lib
fi

export HEED_PREF="$HOME"
export HEEDDIR="$HEED_PREF/heed++"
export HEED_DATABASE="$HOME/heed++/database"

export PATH="$PATH:$WCPPLIBOBJ/install"

AFTER CREATING THIS FILE WHEN I USED THE COMMAND source ~/setup/setup.sh AN ERROR MESSAGE CAME OUT :

bash: 0LD_LIBRARY_PATH: command not found
I HAVE TRIED SEVERAL OPTIOPNS BUT COULDNOT FIX IT .CAN ANYBODY HELP ME IN THIS PROBLEM ? THANKS IN ADVANCE.

$? returns the exit value of previous command (that's where the 0 comes from). What exactly are you trying to do here:

In addition you have to use [] in bash instead of (). You can test if string length is nonzero with [ ! -z "$VARIABLE" ], but you cannot use wildcards (like ?) in variable names (if that was what you tried to do?) As far as I can see, you could just use:

There is no need for the whole if-then-else structure. It doesn't matter if LD_LIBRARY_PATH is previously unset.

THANK YOU
I HAVE TRIED THAT ONE BEFORE BUT THE ERROR MESSAGE IS THEN:

bash: /home/hecrrc/setup/setup2.sh: line 20: syntax error near unexpected token `else'
bash: /home/hecrrc/setup/setup2.sh: line 20: `else '

Thank you verymuch. The problem is solved.

If you really really want the if-statement, you need to make it:

But like I said, you don't really need the if-statement at all. You only need:

I guess, you can change all this to something like

export LD_LIBRARY_PATH=home/hecrrc/CLHEP/lib

EDIT EDIT : Sorry, typing while you said [SOLVED]
