Porting squeak to embedded device
by Ahmed Mansour 10 Aug '10

10 Aug '10

Hello, I'm trying to port Squeak to an embedded platform, but one of the limitations there is not MMU (Memory Management Unit) so the binary must be statically linked and I wonder if it is possible to statically compile it with plug-ins.is it possible to compile just the command line to test and work on the graphic driver and input later?

Hi All, can anyone remember the paper (I think OOPSLA) in which the C++ dispatch model is inverted and instead of having a dispatch table per class indexed by selector id one has a table per selector indexed by class id? TIA Eliot

CMake issue - Xrender not included
by Bert Freudenberg 06 Aug '10

06 Aug '10

Hi Ian, I just noticed a problem with the latest sources. When linking so.vm-display-X11 it is missing the -lXrender even though the cmake log showed it was detected. Also, HAVE_LIBXRENDER appears to be undefined. Instead, CMake seems to define HAVE_LIB_XRENDER. The same problem might happen for HAVE_LIBXEXT / HAVE_LIB_XEXT. I'm attaching a patched vm-display-X11/config.cmake that appears to work fine for me. - Bert -

Adding an external plugin to a VM source tree
by Hilaire Fernandes 05 Aug '10

05 Aug '10

Dear all, We want to add the DBus plugin to this Squeak VM (https://gforge.inria.fr/frs/download.php/26793/squeak-3.11.3.2151-pharo-src…). We are using VMMaker to generate a new C sources plugins directory. We now have a src32 directory but we don't know where to move it. So far we can see Cross/plugin, unix/plugins and unix/src/plugins. Where should we moved our newer C source plugins? Are there any files to edited to reflect this new list? Thanks. Hilaire
