Re: [Pharo-users] NativeBoost Questions while wrapping FMOD

DeNigris wrote > I'm wrapping the FMOD cross-platform audio library > [snip] > I have a few more questions ======== Problem #1: ======== I have the following callout: <primitive: #primitiveNativeCall module: #NativeBoostPlugin> "FMOD_RESULT FMOD_System_Init( FMOD_SYSTEM *system, int maxchannels, FMOD_INITFLAGS flags, void *extradriverdata);" ^ self nbCall: #(FMOD_RESULT System_Init(NBExternalAddress system, 32, 0, nil)). It works fine on Mac. On Windows, it returns some crazy error code that is not listed in the API. However, if I wrap the FMOD DLL in another DLL that just forwards all calls: FMOD_RESULT System_Init(FMOD_SYSTEM *system, int maxchannels, FMOD_INITFLAGS flags, void *extradriverdata) { return FMOD_System_Init(system, maxchannels, flags, extradriverdata); } When I call out to the wrapper DLL, it works! Does that provide a clue as to what's going wrong when calling from NB? Other info: - Other dll functions succeed, so there is communication with the library. In fact, if I proceed past that first error, a sound starts to play... but then the VM crashes... ======== Problem #2: ======== (much less important) I wanted to be able to bundle the DLL with the image so one doesn't have to copy it into the VM folder. If I use the full path for the wrapper DLL described above, it is found, but when it calls fmodL.dll, which is in the same directory, it can't be found. I could only get it to work if at least fmodL.dll is in the VM plugins folder. Is there a way to specify more search locations for dynamic libraries from the image side?

MCRepository can notify by email, did you know?

by Martin Dias

Hi, I just discovered this feature and wanted to share it: When a version is saved, the file repositories check if a file named 'notify' exists in the repository directory [1]. If it exists, then it reads email addresses from that file and send emails notifying the new version [2]. We noticed with Camillo that this seems to be the only usage of SMTPClient in the image. I wonder if somebody is using this feature. Best regards, MartÃn ps: I'm talking of Pharo 3. [1] MCFileBasedRepository>>notifyList [2] MCVersionNotification>>notify:

Re: [Pharo-users] Mugs, mouse mats, stickers

by Esteban A. Maringolo

I had similar issues in the past with a few companies that made stickers for us. Apparently good looking stickers are harder to produce than one might think, I take no chances anymore in that matter, and that's why I recommend Sticker Mule, the quality of the sticker alone will make you want to have one. Regards! ps: In the past I had the intention of making a batch of the same sticker of Pharo, but had no time to deal with the order management and shipping stuff Esteban A.

Re: [Pharo-users] [Athens] Finding if a line passes through a specific pixel .

by kilon alios

yes I am looking at Roassal and definetly it gives a good insight into Athens. Igor you are correct from what I see from the algorithms for finding if a point passes through a curve the work in kinda similar ground. I have to confess I have not looked into it yet, cause I am trying to solve some other problems but I will definitely need this. Right now I try to figure out how to implement my GUI , I want to support Spec so the gui elements ( lets say a button) is rendered by Athens but also called by Spec. Also I want to make something that will easy to port once Athens becomes the main render engine of Pharo and replaces Morphic rendering. But I am happy to say Hyperion is moving forward, a basic vector graphics editor is coming to Pharo ;) On Sun, Nov 24, 2013 at 11:19 AM, StÃ©phane Ducasse < stephane.ducasse(a)inria.fr> wrote: > have a look at roassal because mathieu started to implement something and > he realized it was already in the image. > > On Nov 23, 2013, at 3:20 PM, kilon alios <kilon.alios(a)gmail.com> wrote: > > aaaaaahhh come on ...
