Ffi in Pharo 1.1
Locked
 
|
I noticed in Pharo 1.1 that the loadFFI script in the script loader is no longer there. How can I load FFI into Pharo 1.1. I noticed that the shared library is there but that there are no supporting FFI Classes.
Thanks for the Help. Bruce

Hi Bruce. The recommended way to install external packages in Pharo is now using Metacello.
To install FFI in Pharo, evaluate: Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfFFI'; load. ((Smalltalk at: #ConfigurationOfFFI) project version: '1.3') load. For more information about Metacello: http://code.google.com/p/metacello/ or you can see the talk we give with Dale last week at ESUG.

Hi Mariano,
One thing I don't understand of Metacello is why don't you use #latestVersion (or #latestReleaseVersion, #latestDevelopementVersion, etc) instead of specifying the version number (e.g. '1.3'). How do you keep updated about the latest version numbers? 2010/9/20 Mariano Martinez Peck <[hidden email]>: > Hi Bruce.

I received this about the FFI and getting the latest Version
Hope this helps with the version number. On Mon, Sep 20, 2010 at 12:08 PM, Hernán Morales Durand <[hidden email]> wrote: Hi Mariano, _______________________________________________ Pharo-users mailing list [hidden email] http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-users |

For example, in this case suppose FFI 1.1 is the stable for Pharo 1.0 and FFI 1.3 for Pharo 1.1. How can the user know that? there is no easy solution. This is why Dale, me, stef, marcus, esteban, etc, have been discussed last week in ESUG. I will then send a summary about the possible solution. Anyway, if I use latestVersion, I am not sure you will load that again. Ok....I assumed he was using Pharo 1.1 (because is the current latest stable release). Then, I KNOW that FFI 1.3 works well with Pharo 1.1. If he takes the same image, and in 6 months someone releases FFI 1.4 that doesn't work anymore with Pharo 1.1, then it will fail. Cheers Mariano

As an user I don't want to know the version number until extremely necessary, i.e. I'm not switching everyday from 1.0 to 1.1 to 1.2 then back to 1.1, etc. Eventually I try newer versions of Pharo to see what I'm missing, and I choose to update acoordingly to the stability of the whole set of packages concerning my application. It's not like I evaluate the same "install base packages" script I've evaluated 6 months ago :) By the way if you want to support internally the package status you may try the Specifications pattern? > Anyway, if I use latestVersion, I am not sure you will load that again. I'm sure I will never load it again. Got it? :) > Ok....I assumed he was using Pharo 1.1 (because is the current latest stable > release). Then, I KNOW that FFI 1.3 works well with Pharo 1.1.

Ok, that's your use-case. OThers need exactly that :)
yes. That's a use-case. Fortunatly Metacello is flexible enough to support both. Anyway, did you read my email about stable versions? I think that will clarify everything....since we will be able to use #stableVersion. Cheers Mariano
