I am trying to use a few C library dll and C++ dll from squeak I have the source of the dlls and i am willing to edit the C and C++ code. I still don't fully understand the difference between FFI , external plugins.and build in plugins. from what i understood so far i can't use the dll with OSProcess right ? yetI could not find sample code "hello word" kind for these option. I am trying to get a handle on sqWin32FFI.c . for now . I tried compiling the VC 6 project \platforms\win32\misc\squeqk.dsp I found in the source SqueakVM-Win32-3.10.6-src.zip. with visual studio C++ Express Edition. i got bunch of error C1083: Cannot open include file: 'windows.h': is anyone able to compile squeak with vusual studio. but the source compiles with the gnutools . Thanks, Kemal

Squeak relicensing
by Hilaire Fernandes 06 Dec '07

06 Dec '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I poke again about this to see how it is possible to get updates information regarding the Squeak relicensing situation. Board members of the OFSET organisation for free software in education and teaching is asking me what is the situation. Ten days ago I asked: It may be helpful to have an updated list of the code still posing problem. A ratio of the relicensed code: in term of signed agreement and also in term of line of code (don't know if it is doable). For example it could be very encouraging to realize that 99% of the code is already relicensed. Is there a page in the Squeak wiki showing the work in progress to the public and the free software community particularly?

squeak-vm license in Linux
by José Luis Redrejo 06 Dec '07

06 Dec '07

I can see Squeak license is still the never-ending story, but I'm not so sure for the vm. When downloading the linux sources the license I see is a very free license, without the old Apple restrictions. But I'm not very sure this apply to the full sources, as part of the sources are generated by VMMaker from the image. So, does anybody know a way to guess if the source generated with VMMaker is already relicensed? Thanks in advance.

Preserving class instance variables in Monticello.
by Niko Matsakis 06 Dec '07

06 Dec '07

Hello, I have a project (Pepper) in which we use a few class instance variables. Unfortunately, when we add these classes to the Monticello project on Sourceforge, it seems that the class instance variables disappear (when the changes are loaded into a fresh image, the class instance variables are nil). Is there a way to preserve those instance variables? Also, we overloaded the method "definition" in our base metaclass so as to customize what appears in the System Browser when you visit the class definition, so that the additional variables are displayed. (i.e., instead of "SuperClass subClass:#ClassName ...", it displays custom text of our choosing which omits some fields and adds others). Is this the right way to make such a change? thanks, Niko

FileDirectory fun on XP
by Brian Brown 06 Dec '07

06 Dec '07

Hello, I'm having fun (for some definition of the word) manipulating files and folders from my Squeak image. I am attempting to use FileDirectory>>assureExistenceOfPath: to make sure the folder I currently need actually exists. On default Windows XP installed, the "Simple file sharing" option is on, which shows all folders as read only. Creating folders from the command line works fine, but the DosFileDirectory>>primCreateDirectory: fails a lot of the time. Walking through the process with the Debugger, I am able to verify that the path names are all valid, and I can create the folder in question from the cmd prompt, so I'm at a loss as to why this fails. Could anyone enlighten me on this? - Brian

Box-Admins Team Report for November, 2007
by Ken Causey 05 Dec '07

05 Dec '07

The box-admins team is reponsible for seeing that the community shared server is maintained and setting up any new features to be hosted on that server. For November 2007: Nothing of signicance to report for November. Just at the very end of the month (or technically I believe hours into Decemember) the list server stopped operating. Unfortunately this was on a weekend when I was entirely incommunicado (network-wise). Once I learned of the problem (I believe an email from Jerome Peace was the first I received) I restarted mailman and after a day or so to catch up I think we are back to normal. I want to thank the community for the monetary support needed to fund the box and remind them that the bills continue to appear and that you can currently contribute to the hosting bills by going to http://www.squeak.org/Foundation/SupportSqueak/ and purchasing a Squeak badge. Note that a donation here may be used for other Squeak Foundation services including but not limited to development, development infrastructure, and promotion of Squeak. The services being hosted have continued to grow and include (but are not limited to): http://www.squeak.org/ SqueakMap - http://map.squeak.org/ http://ftp.squeak.org/ http://lists.squeakfoundation.org/ http://discuss.squeakfoundation.org/ http://source.squeakfoundation.org/ http://map.squeak.org/ https://svn.squeak.org/ http://update.squeakfoundation.org/ http://wiki.squeak.org/ http://bugs.squeak.org/ and DNS services for squeak.org and squeakfoundation.org domain names.
