In general there is some advantage in packaging the C-lib with the Smalltalk package for people experimenting with it the first time, to ensure the function prototypes match. But flipping into production may prefer the system library. Currently it seems awkward to switch later to a system library since the library used is hard coded. How do others work around that? Perhaps it would be good to have the external library initialized into an instance variable of FFILIbrary, so a user-application can change the external C-library used without changing code in someone else's ffi-interface package. cheers -ben P.S. On the dream list would be a GUI for managing referenced external C-libraries, including browsing their exported functions.

Re: [Pharo-users] Pharo for MacOs 10.6.8?

EstebanLM wrote > get.pharo.org/30+vm <http://get.pharo.org/30+vm> And if you prefer a GUI over the command line, Launcher automatically downloads images pretty far back (I just confirmed that 1.4 works on a MBP 2017) and matches them up to the correct VM. One caveat: if the image is very old (e.g. the 1.4 above), Launcher will hang when you try to run the DLed image with a "determining correct VM for imageâ¦" dialog. The solution is simple: create a `pharo.version` text file in the image folder with `majorVersionNumber asString, minorVersionNumber asString` (e.g. for Pharo 1.4 -> '14'). That will tell Launcher which VM to use. I happily use Launcher for all my development images. HTH ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

i'm very pleased to! Generally, I'm not a professional programmer. I'm a builder-designer. Ðlthough I have been interested in programming for a long time. Ðnd sometimes I use it. Faro is very elegant, he has a cool debugger and an inspector, in my opinion. Well, you yourself probably know this. I do my home project in my spare time, very slowly. Because of the large amount of basic work now. I want to sort out a bunch of court cases of relatives and related information. Although, probably, some third-party service would make it much easier. Probably, it's more just learning Faro and Spec. Now there are questions how to associate my ComposableModel subclass and a regular class with my code. When I do so "l: = GUI_ListCourtCase new openWithSpec: # defaultSpec2." and try to look at the variable l, I do not see an instance variable that is not related to widgets. I'm trying to initialize it in initializeWidjets, because when I create the method "initialize", I get an error. Worst of all, that i'm not able be in time to investigate the emerging issues myself by the time I get the answers.

Re: [Pharo-users] Pharo for MacOs 10.6.8?

by stefano franchi

Dear Marcus, thanks for the detailed answer. Let me say that my question did not in any ways imply that Pharo should assume the burden of maintaining current images and VMs on old machines. My goal was (is) simply to find out whether it was possible to repurpose a number old machines I have laying around by installing *old* versions of Pharo. And I now have a positive answer, having installed vm30 and verified that it works perfectly. In fact, I think adding a few lines to the website listing the last supported version for the major MacOs releases would be a valuable addition and nicely complement your commendable policy of keeping everything.
