This is jndcalx, a program which exports Lotus Notes calendar entries in iCalendar format. It works for me and it might work for you. I've written a bit about my motivation for creating this.

Snippets of documentation are in the doc/ directory.

You'll need to do the following to build jndcalx on Mac OS X:

• Edit env.mac and set the LOTUS environment variable to the directory containing your notesapi directory.

    export LOTUS="/Users/jpm/Zz"
    export Notes_ExecDirectory="/Applications/Notes.app/Contents/MacOS"
    export DYLD_LIBRARY_PATH=${Notes_ExecDirectory}
  

• Source env.mac

    source env.mac
  

• Make the binary

    make -f Makefile.macosx jndcalx
  

• Test jndcalx by giving it the name of a local (or remote) database. Ensure your copy of Lotus Notes is running or you'll be prompted for a password.

    ./jndcalx jpm.nsf > test.ics
    Notes: Can't open database: err=0x103 [File does not exist]
    ./jndcalx mail/jpm.nsf > test.ics
  

• The resulting file test.ics contains your calendar.

If, and only if, the above was successful, you can continue with the next steps.

You'll need to do the following to run jndcalx on Mac OS X via a CGI wrapper:

• Edit runlotus.c and change the value of DIR to reflect the directory in which you're installing the executable jndcalx. Further set UNIXUID and UNIXGID to the numeric values of your uid and gid respectively.

• Compile the program make runlotus and then make the program setuid to root

    ---s--x--x  1 root  wheel  12708 Sep  7 19:58 runlotus
  

• On Mac OS X I use a CGI script such as that contained in testcal.cgi to launch the program.

If you have improvements to suggest or to make, I'd greatly appreciate patches.
