Hi, I have this which is from a stock 2.3.3 distribution under Solaris: 219 % more start #! /bin/sh reldir=`dirname $0` INST_HOME=`cd $reldir; pwd` export INST_HOME exec /usr/local/bin/python2.1 \ $INST_HOME/z2.py "$@" When started up, this works fine. Looking for INST_HOME in the src tree I get: 220 % find . -print | xargs grep INST_HOME ./inst/make_start.py: varname='INST_HOME' Binary file ./inst/make_start.pyc matches ./start:INST_HOME=`cd $reldir; pwd` ./start:export INST_HOME ./start: $INST_HOME/z2.py "$@" Doing the same for INSTANCE_HOME brings back 52 lines of matches. I'm using the How-To at <http://www.zope.org/Members/4am/instancehome> to have one source installation serve up loads of mini zope sites. It has always worked well under 2.3.0, and here's a 'start' file that does work. Thr python used is 1.52 (Zope 2.3.0) #! /bin/sh reldir=`dirname $0` INSTANCE_HOME=`cd $reldir; pwd` export INSTANCE_HOME PYTHONHOME=/home/zope/Zope-2.3.0-src export PYTHONHOME exec /usr/local/bin/python $PYTHONHOME/z2.py "$@" Whereas this start file under Zope 2.3.3, (note: I've got both INST_HOME and INSTANCE_HOME defined). This is also a python2.1 distribution #! /bin/sh reldir=`dirname $0` INSTANCE_HOME=`cd $reldir; pwd` INST_HOME=`cd $reldir; pwd` export INSTANCE_HOME export INST_HOME PYTHONHOME=/home/zope/Zope-2.3.3-src export PYTHONHOME exec /usr/local/bin/python2.1 $PYTHONHOME/z2.py "$@" Gives an import error 243 % ./start 'import site' failed; use -v for traceback Traceback (most recent call last): File "/home/zope/Zope-2.3.3-src/z2.py", line 296, in ? import os, sys, getopt, string ImportError: No module named os Does anyone know what I'm doing wrong here? -- Dr Tony McDonald, Assistant Director, FMCC, http://www.fmcc.org.uk/ The Medical School, Newcastle University Tel: +44 191 243 6140 A Zope list for UK HE/FE http://www.fmcc.org.uk/mailman/listinfo/zope
