I'm having that currently but, I still can not connect to Postgres. I guess I will have to delve into this quite a bit deeper.

If you have a 64 bit operating system than you can only execute 64 bit executables. In linux there are 32 bit compatibility libraries. The offer a 32 bit interface and mediate this to 64 bit. So you can run a 32 bit vm with compat libraries or native 64 bit vm. The same goes for code that you want to link to the vm. It needs to fit. What the vm internally uses for its address space does not depend on this. I think that is confusing for a lot of people that you can have a 64 bit vm with a 32 bit image. But does anyone know what is the state of 64 bit vm executables? Norbert

Re: [Pharo-project] What is a primitive method?

by Mariano Martinez Peck

THanks Eliot for the explanation. So....The compiler checks and for these kind of special quick methods it creates a CompiledMethod that has in its header, a primitive value ? So...if I would be able to put a "self halt" (but I cannot do it becaue otherwise it won't be quick anymore) in Number>>isNumber, the debugger would never stop there? Interesting!

What's wrong? If you have an antivirus program like nod-32 running, exclude the directory where you have your Pharo image. With Seaside/Aida, another known problem (unrelated to Pharo) is that Firefox on Windows can be very slow if using IPv6. Use 127.0.0.1 instead of localhost.
