I guess Esteban is busy as he is with Stef in Togo. I started porting to new FFI initial stuff and chatted with Esteban on Slack. When you use the latest Pharo 5 image (together with the spur VM) you have the new FFI right inside. Athens is running already on the new FFI. NB is still not unloaded - but it will be unloaded soon. The idea is that people can recover what they need afterwards. For some cases it should be straightforward to convert. A short summary of my findings: - check the "FFI-NB" package in recent Pharo 5 images like Pharo 5 #50510 as of today The name is misleading - it is not the NativeBoost but the new FFI - check the new classes in this package that are prefixed with "FFI" like FFIExternalObject (replacement for NBExternalObject), FFIExternalStructure (replacement for NBExternalStructure), ... - If you generate fields from a struct the accessors are not generated into non-package "*generated-code-non-existing-package" but are now generated into method category "accessing structure variables" and will therefore be part of your MCZ code package - #nbCall: and #nbCall:module: work for compatibility, I guess we should add a deprecation to them - it is better to use ffiCall:, ffiCall:module: now - there is no need to have a pragma with NativeBoostPlugin anymore, at least it worked for me without it just by using #ffiCall: ... - there is a new repo: http://smalltalkhub.com/#!/~Pharo/FFI-NB since last week, but I guess the code in the image is more recent Problems I've experienced so far while trying to port my OS-Windows project: - FIICallout does not understand #optionAt:, no support for options like #WinUnicode so far - FFIExternalType sizeOf: #ulong failed - the spur VM for Windows does not include all latest fixes for Windows VM, like CTRL keys (https://pharo.fogbugz.com/f/cases/17289) Hope this helps a little bit until some more bugs are sorted out/a more detailed info for conversion is available.

We are in the same boat. Even worst, I suspect I am using some parts of ASMJIT which I guess won't be in new FFI, so I have on clue how I would make that parts to work....  On Wed, Dec 23, 2015 at 9:16 AM, Pierce Ng <pierce@samadhiweb.com> wrote:Hi, (For Esteban perhaps...) Is there an image/VM combo to preview the new FFI? I just made NBSQLite3 work with SQLcipher (for transparent database encryption) but don't want to spend any effort refactoring if I need to redo for the new FFI.
