Have you seen https://ci.inria.fr/moose/job/moose-7.0/ ? Roassal is loaded on it.

UFFI uses the method source code to map arguments, and if no source code is available, FFI calls cannot be resolved. This is solved in Pharo7 thanks to Vincent Blondeau by embedding argument names into the method (and thus not requiring source code anymore). If you need it, you can take the FFICompilerPlugin class + (RBMethodNode>>ensureCachedArgumentNames) from Pharo7 and try to backport them on your Pharo6 installation.

Hi, You may want to look at https://github.com/VincentBlondeau/Cruiser that contains all the actions needed to perform a clean packaging (Still in dev though). The only issue is that it works for Pharo 7 only and youâll need to backport changes (I can help you on that). Some changes are related to new VM primitives so you have to use the current stable one (which should also running the Pharo 6.1 images). Donât hesitate to ask me if you need advices or help on this. I could try to make the tool work on Pharo 6, but it could be incomplete especially on the FFI and stdio part.

No, the money isn't lost. I was merely suggesting that without some help, the marketing opportunity for this competition would be lost. I'm not sure you understand how much work is involved in this project. I will be doing a great deal of the heavy lifting. I have to setup the competition website server. I have to advertise or reach out to high schools across the country. I have to get local media interested in covering the competition. I have to look into producing the T-shirt swag, and shipping the T-shirts to all contest participants, and at an affordable rate to fit the budget. Those are only a few things off the top of my head. Coding the actual contest problems according to David Buck's prescription shouldn't be open-ended and shouldn't be a huge commitment. I imagine it would be a couple of months of work during spare time. jgfoster wrote > Hi Richard, > > So the $$$$ that we gave you is now âlost"?

That could be a 10 to 20 day commitment at a $1000/day - who knows from the scope you've presented. Its like your asking for a blank cheque. And it "feels" like the full onus would be on the developer and that responsibility can be off-putting. Even people that may be inclined to help may not have the spare cycles for that commitment. They can be already be doing a *lot* of volunteer time to help Pharo which suits their priorities. Even people who believe your project is a priority may be caught up in commitments they can't drop. So there are a lot of precondition hurdles you need to hurdle to get helpers. So what you are doing is kicking off an "new" open source project. And further, in essence what you are doing is building a mini-community of helpers (even if that is one helper, and notice the distinction from pure volunteer). Now as ESR says... "When you start community-building, what you need to be able to present is a plausible promise. Your program doesn't have to work particularly well. It can be crude, buggy, incomplete, and poorly documented. What it must not fail to do is (a) run, and (b) convince potential co-developers that it can be evolved into something really neat in the foreseeable future." http://www.catb.org/esr/writings/cathedral-bazaar/cathedral-bazaar/ar01s10.… > I am nowhere near qualified to do so, as my knowledge of Pharo is limited. >> > This is a red herring. The majority of your "plausible promise" is the model, with unit tests demonstrating its operation. That should be able to be coded platform independently. When you progress to needing platform specific knowledge (e.g. gui, networking, web framerworks) you can start by asking specific questions in relation to your "plausible promise". You can encourage people can install your "plausible promise" on their machines to provide concrete examples to help the discussion, The trick is, once someone has installed your "plausible promise" and see it working in their infancy it becomes much more real for them, sparks ideas for small improvements and they are *much* more likely be inspired to help you. So personally, in general I'm open to helping (and I'm quite susceptible to being deeply drawn in) I'm just not inspired enough right now to drop any of my other commitments to take the lead with this. >> Without help from Pharoers (or, at least, Smalltalkers), the competition >> is in jeopardy.

Hi Richard, So the $$$$ that we gave you is now âlost"? Perhaps people didnât understand what you expected from us other than money. What else is needed to make your project a success? We are supposed to âcode the competitionâ as well? Anything else? Is this practice of insulting people (âDoesnât anyone care about promoting Pharo?â) supposed to be motivating? Is it a demonstration of you expertise at marketing? Does it build confidence about how the Smalltalk community will be perceived by the new arrivals?
