Installing GlorpDBX on Pharo 1.1

by Esteban A. Maringolo

Hi All, What do I have to do to get GlorpDBX installed on a Pharo 1.1 beta image? Sorry, but I'm new to the Gofer, Metacello, Monticello, Installer ss and all those utilities. Every time I try to catch up, it's always a step ahead of me :) Thank you! -- View this message in context: http://forum.world.st/Installing-GlorpDBX-on-Pharo-1-1-tp2263345p2263345.ht… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Subclasses of classes in the specialObjectsArray create instances of their superclass when sent #new or #basicNew. I have already submitted a bug report for Pharo and should probably enter a similar one for Squeak: http://code.google.com/p/pharo/issues/detail?id=2523 I have tested this only on Mac OS X 10.6, so it is possible that only the Mac OS X VM has this problem. It should be easy to check if it happens with other VMs too. Concerning contributions to Pharo and Squeak: I will restrict my work to JNIPort and won't get involved in any work on Pharo or Squeak. The reason is that I have a very limited amount of time to spend on open source projects, so I have to draw a strict borderline. Cheers, Joachim Geidel

Hi Mariano Thanks for the links. I managed to dig out my old code and found some of the links, enough for me to write the slang and convert to C. Now I need some header files for the build and presumable a library to link against. I would appreciate a pointer to those as it's not obvious from the links where to get those from.
