OpenCyc

If you download the Linux release and replace the contents of server/cyc/run/bin/run-cyc.sh with the below, it runs on at least Snow Leopard: #!/bin/bash # # $Id: run-cyc.sh 126951 2009-01-28 18:55:50Z tbrussea $ # Assumes that java 1.5 or higher (1.6 or higher preferably) is in your path if [ ${PWD:(-4)} == "/bin" ]; then # we are inside the bin directory ... moving one level up quietly cd .. else if [ -d ${PWD}/lib ]; then # this is the correct location, we are good : else echo "I do not think that CYC is installed here." exit -1 fi fi if [ `uname -s` = "Darwin" ]; then CLASSPATH="lib/cyc.jar:lib/subl.jar:lib/junit.jar:resource:lib/ext:plugins" else CLASSPATH= PATH_ELEMENTS="lib/cyc.jar lib/subl.jar lib/junit.jar resource lib/ext plugins" for pathElement in ${PATH_ELEMENTS}; do canonicalElement=`readlink ${pathElement}` if test -z "${CLASSPATH}"; then CLASSPATH=${canonicalElement} else CLASSPATH=${CLASSPATH}:${canonicalElement} fi done fi echo CLASSPATH $CLASSPATH _JAVA_OPTIONS= # Add the following line to the JVM options to allow remote debugging # -agentlib:jdwp=transport=dt_socket,server=y,address=8888,suspend=n BIT_FLAG= if [ `uname -s` = "SunOS" ]; then java -d64 -Xmx5000m -version > /dev/null 2>&1; if [ $? -eq 0 ]; then echo "Running Solaris with 64 bit Java ...."

That got munged. Need to at least replace " with double quotes. Can't see anywhere to post a file here, but I've contacted johndcyc about updating the release.

The new part is: if [ `uname -s` = "Darwin" ]; then CLASSPATH="lib/cyc.jar:lib/subl.jar:lib/junit.jar:resource:lib/ext:plugins" else

so, is this for real? we can finally run on macintosh? has anyone confirmed this? does it work? will somebody make an installer for this?

It's a Java app; all that's needed is the right launch script.

okay, so, like, "for n00bs", what are the step by step instructions?

i got Open Cyc running on osx snow leopard . change the shell script to remove '/' to mark a continued line and put all that on the same line . run it in the 'server/cyc/run' directory .

I'm on snow leopard (10.6.4). The unique modification I've had to do is on opencyc-2.0/server/cyc/run/run-cyc.sh, where I've had to change: canonicalElement=`readlink -f ${pathElement}` into: canonicalElement=`stat -f "%N" ${pathElement}` ... and that's all. (It seems there a problem with command readlink)

You can also install coreutils with brew which will give you the GNU version of readlink (greadlink). Then you change the following in server/cyc/run/bin/run-cyc.sh if [ `uname -s` = "Darwin" ]; then READLINK="greadlink" else READLINK="readlink" fi CLASSPATH= PATH_ELEMENTS="lib/cyc.jar lib/subl.jar lib/junit.jar resource lib/ext plugins" for pathElement in ${PATH_ELEMENTS}; do canonicalElement=`${READLINK} -f ${pathElement}`
