Hi Paul,
Thanks for the clear instructions. I installed the 4.1.25 BerkeleyDB from the
Oracle site. That looks like the right place to start.
Are you working on a 32-bit Ubuntu system, or 64-bit? I'm working on a 64-bit
platform, and I think I'm seeing a few issues to be sorted out (nothing serious,
more or less what I'd expect on a plugin that has not be updated in a while):
[100%] Building C object BerkeleyDbPlugin/CMakeFiles/BerkeleyDbPlugin.dir/home/lewis/squeak/VM/src/plugins/BerkeleyDbPlugin/Berk
eleyDbPlugin.c.o
/home/lewis/squeak/VM/src/plugins/BerkeleyDbPlugin/BerkeleyDbPlugin.c: In function \xe2\x80\x98dbValueOf\xe2\x80\x99:
/home/lewis/squeak/VM/src/plugins/BerkeleyDbPlugin/BerkeleyDbPlugin.c:100:9: warning: cast to pointer from integer of different
size [-Wint-to-pointer-cast]
return (Database *) (oop + 4);
^
I may not have time to really look at this for a few days, but I think if
we can get the plugin working on the older BerkeleyDB version, then the
updates should be straightforward from there.
Thanks also for setting up https://github.com/pdebruic/BerkeleyDBPlugin
