We did the OpenDBX wrapper with FFI, but we needed only one ExternalStructure. Anyway, if you want to take a look, load the packages OpenDBXDriverPharo-Dialect and OpenDBXDriverSmalltalk-Dialect from ' http://www.squeaksource.com/DBXTalk' and browse methods of PharoOpenDBX subclasses. > Finally is there a way to get external variables such as 'extern int > errno;' ? > > Thanks in advance! > > ../Dave > > -- Mariano http://marianopeck.wordpress.com

And it looks like 1.4 will last quite long until it will be released. no it can be fast. One of the point is to have the code under our nose so that we can really integrate code.

Are they all of equal importance? To me it sounds really a lot. And it looks like 1.4 will last quite long until it will be released. What happened to the zinc integration btw.?
