To address that we usually write tests. :) But it is hard, especially in domain of FFI, where external function/library is completely opaque ( you cannot see what happens there, and what is involved there). Especially that most of functions are far from being fault tolerant and idiot proof: if you pass nil pointer to some function which expects only a valid address, it will most probably just crash the whole thing instead of throwing nice exception, which you can handle and therefore build your tests cases on top of it. ah yes.. btw.. if you think that VM is busy doing something but irresponsible, you can send a SIGUSR1 to it to see what it does. > > On Fri, May 18, 2012 at 5:29 PM, Igor Stasenko <siguctua(a)gmail.com> wrote: >> >> On 18 May 2012 07:34, chadwick <mathnoir(a)gmail.com> wrote: >> > >> >> >> >> yeah.. but make sure you linking with right 32bit lib.. otherwise you >> >> will get things like that. >> >> >> > >> > >> > ok I changed the FFI path to OpenGL library to >> > >> > /usr/lib32/nvidia-current-updates/libGL.so.1/usr/lib32/nvidia-current-updates/libGL.so.1 >> > >> > and now >> > >> > GLTTRenderingDemo new openInWorld. >> > >> > does something, i.e. there's no error either in Pharo or in the console, >> > but >> > I don't see anything, there's just a sense that something is being >> > computed >> > as the machine runs slower. >> > >> hard to say anything. looks like it renders something somewhere but >> then results are lost. >> >> >> -- >> Best regards, >> Igor Stasenko. >> > > > > -- > Lic.

it depends. Sometimes, passing a wrong type of argument through nbffi (because of a badly wrapped signature), breaks the VM, almost but not completely freezing it while consuming 100% CPU. Maybe this is happening, but in that case the native window would probably not open.

Well, two things should happen: a native window should be opened which shows nothing (context creation should be fixed to not create it), and also a morph should be opened in world, rendering some text through opengl. Does the window get opened? does the image freeze?

Ben I found a way to reproduce my problem, take 20076 in a workspace forPackage: sur MCPackageManager forPackage: + act M puis un click sur initialize puis un autre click sur initialize -> problem The icon navigation works but we cannot see the code. Stef
