Interesting, I expected that it is based directly on the name of the Pharos island where lighthouse of Alexandria was located :-) Btw. do we have got an SVG version of the Pharo logo? -- Pavel On Thu, Oct 25, 2012 at 11:33 AM, Marcus Denker <marcus.denker(a)inria.fr> wrote: > > On Oct 25, 2012, at 11:24 AM, "Peter H.

If it comes to dynamic libs there is a source for failure. The library setup is not the same for every e.g. linux. So the prerequisites are compiled into the library but there is nothing to check at installation time. The vm is distributed in a plain file archive and not in an installation package. Building package for each platform could solve it :) I'm thinking since a longer time to package the vm for me so my deployment time will be reduced. It isn't very hard to build those packages. > > Norbert Hmm. it still feels as if it should be possible to build the SSL plugin in another environment. After all, the VM itself also has dynamic library dependencies that seems to work on multiple platforms without installers. If at all possible, we should try to keep the vm as simple as possible.
