[Pharo-project] Understanding NBOpengl
by dimitris chloupis May 8, 2013

May 8, 2013

Ok so I tried to learn Opengl ES 2 (and opengl 4) during my eastern vacations because I realised that I dont really need Athens or vector graphics for my GUI , since I will be dealing mostly with 3d graphics anyway. (My project "ephestos" will be an effort of creating a 3d app for pharo, see also "blender") So when I tried to run the demos i get an error with NBMacGLContextDriver>>supportsCurrentPlatform Â Â Â "obviously, for Mac intel-32 only :)" Â Â Â ^ NativeBoost platformId = NativeBoostConstants mac32PlaformId My mac is "obviously" not 32-bit but 64 bit, but I dont know if that matters since pharo is only 32 bit anyway. The bug is also obvious it should be mac32PlatformId and not mac32PlaformId. I correct and proceed and gives me a new error this time in NBMacGlApi>>glApiCall: fnSpec index: fnIndex attributes: attributes context: contextToRetry Â Â Â ^[ Â Â Â Â Â Â (NBCallFailureHandler for: contextToRetry) retryWith: [ :targetClass :targetMethod | Â Â Â Â Â Â Â Â Â (NBFFICallout Â Â Â Â Â Â Â Â Â Â Â Â targetClass: targetClass targetMethod: targetMethod fnSpec: fnSpec) Â Â Â Â Â Â Â Â Â Â Â Â stdcall; Â Â Â Â Â Â Â Â Â Â Â Â generate: [ :gen | self emitCall: fnIndex generator: gen ] Â Â Â Â Â Â ] Â Â Â ] on: NBNativeCodeError do: [:err :handler | Â Â Â Â Â Â err errorCode = ErrorFnNotAvailable ifTrue: [ Â Â Â Â Â Â Â Â Â "Native code is installed, but function pointer not loaded yet. Â Â Â Â Â Â Â Â Â Try to load function and retry the call"Â Â Â Â Â Â Â Â Â Â Â Â (self tryGetFunctionPointer: (self class glFunctions at: fnIndex)) ifFalse: [ ^ err pass ]. Â Â Â Â Â Â Â Â Â ^ handler retrySend Â Â Â Â Â Â Â Â Â ]. Â Â Â Â Â Â err passÂ Â Â Â Â Â Â Â Â ] The problem here that NBCallFailureHandler is nowhere to be found. At first I though my NB was lagging behind in version so I download from smalltalk Hub and did ConfigurationOfNativeboost loadStable. it updated without errors but still that class is nowhere to be found. So my question is this, does it really worth it to struggle with NBOpengl or will it better to learn how Nativeboost works and use Opengl myself ?

Something like that would make sense for people who want to get an exact copy of their project: | source goSource destination goDestination files destinationFiles | source := MCHttpRepository location: 'http://www.squeaksource.com/YOURPROJECT'. destination := MCSmalltalkhubRepository owner: 'YOURNAME' project: 'YOURPROJECT' user: 'YOURNAME' password: 'YOURPASSWORD'. goSource := Gofer new repository: source. goDestination := Gofer new repository: destination. files := source allVersionNames.

[Pharo-project] the future of squeaksource
by Andrei Vasile Chis May 8, 2013

May 8, 2013

Hi all, Given that SmalltalkHub is now stable we were considering to discontinue SqueakSource. Our idea is to provide a grace period of a couple of months to allow the current active users to migrate their projects to the new service and then simply put squeaksource in read-only mode (simply exposing the directory structure and allowing downloads). What do you think about it ? Are there any good reasons to still keep SqueakSource alive? Cheers, The SCG Team

I was wondering if there is a magic CLI command to load a slice ? I do not see it in the help :) I think it could be useful :) Ben
