Re: [Pharo-project] Bugreport?

by bb

There is a SqueakVM for 64 bit as well, see: http://www.squeakvm.org/squeak64/ As squeak is running on my machine with fedora13 64 bit WITHOUT the 32 bit libGLU.so.1 (as I have explained in another mail, the only libGLU is in the directory /usr/lib64) one can make sure that there is a 64 bit version running (and offered in the fedora13 64 bit repository, from where I have installed). Vice verse, on my 64 bit debian lenny installation squeak does not run. On that system as (nearly) only the 32 bit libs installed. (I will analyse that case if I find some time.) There seems to be a situation of shift to 64 bit with some library breaks in different systems. Indeed it is possible to install the 32 bit libs with apt-get on debian like machines and yum or rpm or other tools on other linux brands. That would not help so much because it does not solve he incompatibility of my installed 64 bit SqueakVM running on my machine with the 32 bit pharo-image. (I have not yet tried, but in this logic I would have to install a 32 bit squeak as well.) The file vm-display-X11 of my actual squeak version is in directory /usr/lib64/squeak/3.10-5. I tried to change pharo.sh to point explicitely to that directory to use that vm. The result: ~ Pharo-1.1-OneClick.app$ ./pharo2.sh libGLU.so.1: wrong ELF class: ELFCLASS64 could not find display driver vm-display-X11; either: - check that /usr/local/lib/squeak/4.0.3-2202/vm-display-X11.so exists, or - use the '-plugins <path>' option to tell me where it is, or - remove DISPLAY from your environment. Abgebrochen (Speicherabzug geschrieben) ~ Pharo-1.1-OneClick.app$ As you can see pharo is looking for the vm of squeak version 4.0.3-2202 instead of 3.10-5. I do not know where to change this path in pharo and if it makes sense? I do not understand, that there are so.*-versions in .../Contents/Linux/? In my oppinion the clean and save solution for the future is to provide an additional 64 bit pharo-image beside the 32 bit version.

In that case you're using OCompletion. If you load it's latest version, it should be significantly faster. Here's a script for loading it: Gofer new squeaksource: 'OCompletion'; package: 'Ocompletion'; load. This solves all but two bottlenecks (which are related to Shout). One of them can be fixed by filing in this patch: http://leves.web.elte.hu/squeak/SystemDictionary.ul.1.cs Here's a script to do it: 'http://leves.web.elte.hu/squeak/SystemDictionary.ul.1.cs' asUrl retrieveContents contentStream fileInAnnouncing: 'Loading...'. I'm working on the solution for the last bottleneck (which occurs when your code doesn't look like Smalltalk code at all, or when it sends several unimplemented messages), but that probably doesn't bite you at all.
