[Vm-dev] Re: [squeak-dev] Crypto plugins for ubuntu 32-bits

Mon Dec 7 04:08:33 UTC 2015

Hi Robert,

I'm attaching a couple of pictures to show the difference. Version 9
is missing the class side methods for DSAPlugin.

I am compiling on a 64-bit environment (partly in order to be able to
identify issues like this). The #declareCVarsIn: method is needed in
order to declare some variables as (possibly 64-bit) pointers, and I
presume that the #moduleName method is needed for other reasons.

It may be that the plugin would compile on a 32-bit host, and possibly
that is why it's working for you. But the two missing methods are
important. I suspect that they just went missing by accident somewhere
in the updates and merges in the Cryptography repository, so if you can
add them back and save the update as CryptographyPlugins-rww.10.mcz
then I think all will be well.

Dave
