You just need to uncompres it, and in the folder Pharo1.0-10440-BETAdev09.09ONECLICK.4.app you will see you have a .exe for windows, a .sh for linux, etc. So, just double click on Pharo.sh and it should work.

I downloaded your image on my windows and created the image with the corresponding web app. The VM on my Linux is still the same and I still receive the same error message.

Yes I took the version called "Linux and other unix (0.15.2d)" And my windows Pharo is from the pharo-project.org page, as well (even though a little older probably - talking about 2 or 3 months). 2009/10/16 StÃ©phane Ducasse <stephane.ducasse(a)inria.fr> > thanks peter. > I'm that one of our linux friend will answer your question. > > > On Oct 16, 2009, at 10:29 AM, Peter Osburg wrote: > > > Hi folks, > > > > I downloaded the latest Linux version of Pharo.

First preconditions in eiffel have different level of execution you can completely disable them. Once the new compiler is in pharo and the default compiler we could do really cool on the fly recompilation and have a large range of choices. Then we can use preconditions to generate tests or as one of my friend did in eiffel and java generate tests that you trash after and enhance the robustness of the preconditions. I read the PhD of benoit baudry and once you read the conclusions and the results it is clear that preconditions have really good properties. Now we have to be smart enough to understand how we can take advantage of them in our setup. > 2) Readability: 3 lines of assertions for two lines of code is too > much to my taste. > Opinions may vary...

[Pharo-project] This interpreter (vers. 6502) cannot read image file (vers. 6504)

by Peter Osburg

Hi folks, I downloaded the latest Linux version of Pharo. I did as it is told in the README.txt But I when I want to start with my image, I receive the following error message: "This interpreter (vers. 6502) cannot read image file (vers. 6504)" I have to tell you that I tried to start Pharo on a 64bit Linux (32bit libraries are installed). The image itself was created under Windows and the latest Pharo for Win VM. Is there a compatibility issue between windows images and linux images? How can I solve the problem? Many thanks in advance, Peter -- www.peter-osburg.de www.experiencedwebprogramming.com www.mix-rss.com
