Could you change the script to something like this? Is it necessary to
run dirname under the old kernel version? Seems the output should be
the same over versions of the library.
DIR_NAME = `dirname $0`
export LD_ASSUME_KERNEL=2.4.1
case $0 in
*/*) exec $DIR_NAME/maple -x $*
;;
*) exec maple -x $*
;;
esac
In fact, I'm not sure why you have the case statement, since dirname
returns a . if there is no directory path.
Should just be able to do
DIR_NAME=`dirname $0`
export LD_ASSUME_KERNEL=2.4.1
exec $DIR_NAME/maple -x $*
Is this way off the wall? Seems like it should work.
Thank you for the suggestion. Actually, that is a good idea, instead I
took it a step further by moving the "export LD_ASSUME_KERNEL=2.4.1" to
where the actual binary is called to be executed in the script named
"maple." So the bottom of the "maple" script looks like this:
#############
if [ "$XMAPLE" ]
then
export LD_ASSUME_KERNEL=2.4.1
exec ${MAPLE}/$MAPLE_SYS_BIN/maplew $IPARAM $DISPLAYARG $PARAM
else
if [ "$IPARAM" ]
then
echo "$0: invalid parameters: $IPARAM"
else
export LD_ASSUME_KERNEL=2.4.1
exec ${MAPLE}/$MAPLE_SYS_BIN/cmaple $INCLUDES $PARAM
fi
fi
############
Doing that, I get this error message:
/usr/local/maple_su/bin.IBM_INTEL_LINUX/maplew: error while loading
shared libraries: libdl.so.2: cannot open shared object file: No such
file or directory
OK, does anyone else think it's bizarre that just because the FC10 glibc
lacks LinuxThreads, that I'm getting a missing library file error when
that library is actually installed on my system? Anyway, I guess that's
why everyone on here is still saying to avoid closed-source software...
anyone know of any open-source computer algebra software?
Peace,
William
