Hi Dave,
I've made a repository here: https://github.com/pdebruic/BerkeleyDBPlugin and added you as a collaborator. I have not yet made any changes in the files from the .sar.
I did find that if I used version 4.1.25 then things compiled without the errors I posted yesterday and a VM was made. So I think we need to start with older versions of BerkeleyDB, which apt doesn't have. I did not yet try the other 4.x versions and I'm not sure which would be best to use.
The 4.x versions are available here: http://www.oracle.com/technetwork/database/database-technologies/berkeleydb/....
They include install directions and C API documentation accessible from the docs/index.html file once you've extracted the download. Once unzipped the install steps were:
cd build_unix ../dist/configure make sudo make install
Thanks for taking a look

Hi Paul,
I'm sure we'll want to put the source in Subversion at some point, but github might be a good way to get started. I am dtlewis290 on github.
I have not actually installed berkeley DB on my ubuntu PC yet. Should I just apt-get it from ubuntu, or is there a particular version that I should try to use?
Thanks!
Dave
Hi David,
I followed your instructions and made some headway in getting the plugin compiled. The changes are on SquaeakSource. I think I have now hit some errors that will necessitate making changes to the sqBerkeleyDbPlugin.c file in the .sar.
Where should I save/share those changes?
I'm ambivalent and will put it on github if you are too.
I'm using 32 bit ubuntu 14.04. I think the current Big problem is that the plugin was written for BerkeleyDB version 4.???. I've been trying to compile it against version 6.1, because its the current stable installed by apt-get. Maybe the API has changed. I'll download and try some of the 4.x libraries to see.
The current set of errors are pasted below.
I've got about an hour a week I want to spend on this so there is no rush on my end for Progress.
Thanks for taking a look

Hi Paul,
Thanks for doing this. I don't have time to really check it out right now, but I did load your code from the new repository and I was able to generate the C source with no problem (see attached).
I'll follow up on this in a few days, but at first glance it looks fine.
FYI, I'm using VMMaker trunk (load update-dtl.16.mcm), then "VMMakerTool forUnix" to open the VMM tool, then drag the BerkeleyDbPlugin from "Plugins not built" over to the "External Plugins" pane, then Generate Entire.
For platforms source, I used the sources from the original SAR and put the header file in platforms/Cross/plugins/BerkeleyDbPlugin/ and the C file in platforms/unix/plugins/BerkeleyDbPlugin/. I don't know if that's right, but it works for generating the C code.

Hi David,
I made the project on SqueakSource. The repo is here:
MCHttpRepository location: 'http://www.squeaksource.com/BerkeleyDB' user: '' password: ''
When attempting to generate the plugin as an external plugin the error shown in the VMMaker window is:
warning, variable simulator doesn't exist or has already been removed failed to inline getErrorMessage: as it contains unrenamable C declarations or C code warning, signature of InterpreterProxy>>instantiateClass:indexableSize: does not match reference implementation. external plugin BerkeleyDbPlugin generated as BerkeleyDbPlugin 5 April 2015 9:00:18 am
Are these warnings/errors serious? Is the next step to get rid of them?
Thanks

I am assuming that this is "Berkeley DB Plugin" on SqueakMap, written
by
Stephen Pair and licensed SqueakL, and therefore OK to include in the VM.
The SAR file contains the platforms sources and some hints as to
handle it
in a makefile.
I expect that this plugin could be brought back to life with a bit of effort. It also looks like something that might best be maintained outside of VMMaker so that the interested parties can update it as they please.
How about if we put the Smalltalk part of the plugin into a new
project on
squeaksource.com? Paul DeBruicker, Stephen Pair, Eliot and I all have accounts on that server already, so it would be easy to put it there.
The Berkeley db library has a lot of history, and I don't know what
the
current runtimes would be on a modern unix/linux/osx platform. The http://www.sleepycat.com site redirects to Oracle now, which does not seem encouraging.
Current
licensing seems to be explained at http://en.wikipedia.org/wiki/Berkeley_DB.
