[Vm-dev] Re: updating and compiling the BerkeleyDB plugin

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/downloads/index-082944.html.

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


Paul
