The one-click vm appears to still have the defect. -----Original Message----- From: pharo-project-bounces@lists.gforge.inria.fr [mailto:pharo-project-bounces@lists.gforge.inria.fr] On Behalf Of Schwab,Wilhelm K Sent: Tuesday, April 06, 2010 5:12 PM To: Pharo-project@lists.gforge.inria.fr Subject: Re: [Pharo-project] FFI+Linux+double return value Nicolas, I tried, and it has not been smooth. What exactly do you mean by the library path? Perhaps the easiest way to answer my question is to tell me which libraries should be found there. Will the vm no longer use absolute paths in #moduleName? I moved on to the RC3 one-click image and am trying to figure out how to point its vm at my image - can't hurt.

Hello all,
I built (I think) a 2151 vm, but I can't run it. Â It keeps complaining that it can't find the X11 display driver. Â What am I missing about the command line options? Â I generally try to use
 /full-path-to-vm/squeakvm options /full-path-to-image
Help??
Bill
Unless you add some specific home made plugin, you should better use latest squeak vm, after setting the LD_LIBRARY_PATH to point to your library path. Did you try ? Nicolas

Nicolas,
I am running this on Ubuntu (9.10) and have been using the Pharo 0.15.2f vm. Â I just tried a Squeak vm (3.11-3) and could not get it to load my library. Â I have been using an absolute path the the .so; could that be the problem with the Squeak vm??
There has been a lot of discussion of the Pharo Linux vm lately, with some links and corrections, so I'll have to look around a little.
You asked if I can check the vm sources; the concern is whether or not I will have anything to add :) Â Is there something specific you want me to do?
Bill

Hello all,
I had some strange results with double return values and boiled it down to a C function
Double AnyDouble() { Â Â Â Â return 1.0; }
called via
 anyDouble  < cdecl: double 'AnyDouble' () >
and driven by
| out | out := Array writeStream. 100 timesRepeat:[ Â out nextPut:Library default anyDouble ]. out contents.
The results are not good. Â It works for the first three elements, after which it produces NaN. Â The real problem appears to be comparison of floats being broken after that point, as evidenced by a walkback that arises when trying to inspect the resulting collection - exploring it works.
I need to try this on the latest image/vm, but wanted to start gathering opinions. Â Any ideas?
Bill
