[Pharo-project] Best way for FFI in Pharo
by Udo Schneider Jan. 20, 2012

Jan. 20, 2012

All, what's the best way (at the moment & in the future) to call external libraries from Pharo. I'm a bit confused at the moment will all the stuff going around FFI, NativeBoost ... Is there maybe an abstraction layer above all those native-call mechanisms somewhere? Best Regards, Udo

The latest video in the saga: http://www.youtube.com/watch?v=TsJmBwi9lDY BTW, the video I mentioned a day or so ago now has 90 views, in only 3 days. People who want to promote squeak/pharo/seaside/etc to the world at large should take note. L.

[Pharo-project] speeding up copying World using dirty rectangles?
by Lawson English Jan. 20, 2012

Jan. 20, 2012

in my Gui to OpenGL code, I'm doing a very naive procedure to copy the World to an OpenGL at every #step. I know that there's many ways to speed this up (I get only 10fps with a saturated core when I do it the simplest way). Suggestsion on how to make the following more efficient? THanks. getLatestImageFromWorld |format form tempTextures| pasteUpFormCanvas ifNil: [^self]. self hide. myPasteUp fullDrawOn: pasteUpFormCanvas. self show. form := pasteUpFormCanvas form. fPUWidth := form width. fPUHeight := form height. tempTextures := WordArray with: (textureIntNames at: 1). ogl glDeleteTextures: 1 with: tempTextures. ogl glBindTexture: GLTexture2d with: (textureIntNames at: 1). ogl checkForError. format := ogl textureInternalFormat. ogl glEnable: GLTexture2d. ogl glTexParameteri: GLTexture2d with: GLTextureMinFilter with: GLLinear. ogl glTexParameteri: GLTexture2d with: GLTextureMagFilter with: GLLinear. ogl glTexImage2D: GLTexture2d with: 0 with: format with: form width with: form height with: 0 with: ogl texturePixelFormat with: ogl texturePixelType with: form bits.

[Pharo-project] Which COG VM?
by Torsten Bergmann Jan. 20, 2012

Jan. 20, 2012

Unfortunately the VM from the one click package has a bug when it comes to FFI. You can download latest Cog from Eliots archive: http://www.mirandabanda.org/files/Cog/VM/?C=M;O=D No need to compile here. I use them too. Note that Eliots one (with source managed in subversion) is not the "official pharo VM", but the "official CogVM" for Squeak and Pharo. Pharo has its own fork and which is github managed. >From time to time Igor moves fixes from Eliots CogVM into the Pharo Cog VM. At least thats how I understood it ...

[Pharo-project] Swazoo + openID
by Bernat Romagosa Jan. 19, 2012

Jan. 19, 2012

Hi list, We need to log a user into an application (not a Seaside app) using their google account, and we are using Swazoo as a server. It must be their google account because we need to retrieve and modify stuff stored in their google world (Blogger, Calendar, etc). We've taken a look at CloudFork, but it seems to be tied to Seaside and looks very complicated to use... are there any simpler alternatives? I guess the ideal solution would be to have a Swazoo extension that handled the authentication, is that right? Thanks! -- Bernat Romagosa.

Re: [Pharo-project] can't infer base LD_LIBRARY_PATH. Aborting.
by mkobetic＠gmail.com Jan. 19, 2012

Jan. 19, 2012

Most probably know this, but just in case, recent versions of Linux distributions provide a more modular way to control the library path via the /etc/ld.so.conf.d/ directory. For example I normally add path to oracle libraries by adding a file /etc/ld.so.conf.d/oracle-11.1-x86_64.conf with just a single line in it containing /usr/lib/oracle/11.1/client64/lib. I think you need to run ldconfig every time you modify the directory, but after that the library should be visible to all programs. You can add both 32 and 64 bit libraries this way. Not sure if this is immediately useful to help with this problem, but there it is.

Hi With the latest cog VMs I get: can't infer base LD_LIBRARY_PATH. Aborting. Gentoo 64bit, Linux 3.1 LD_LIBRARY_PATH is not set but libtool is present. Cheers Philippe
