I don't get it, the code you posted looks ok. RBClass is a class private to the framework, you should never need to instantiate it directly. And if you do, only through an instance of RBNamespace that provides a delta to the current system state.

Re: [Pharo-users] Updated ConfigurationsOf...scripts?

by HernÃ¡n Morales Durand

Ok if there are not, I think is a must, I spend a lot of time searching for the updated scripts or exporting/importing them in my images. What about creating a wiki page in the google project?

If you file in the attached dummy class and evaluate the following script should be reproduceable: | className realClass replacer category | className := #MyClass. realClass := Smalltalk at: className. category := #accessing. replacer := RBParseTreeRewriter new replace: '`receiver asString' with: '`receiver asText'; yourself.

The stack-trace and your code snippet does not match. There are no references (and should be no references) to #compileTree: or RBClass in the code you pasted into the mail. The easiest is probably if you use the refactoring tools as integrated into OB. This does all automatically.

squeak vm without MMU

by Annick Fron

Hi, Is it possible to use pharo on a processor with MMU (Memory Unit Management ) ? Namely my target OS is a Linux with the following differences : ============ The kernel is a collection of patches to make the standard Linux kernel run on CPUs that do not have an MMU. As a consequence you will encounter some differences between the kernel and the standard Linux behavior: u no fork() â consider using vfork() instead but beware of the difference of their semantics u no daemon() â it is usually implemented on top of fork and cannot be easily replaced without changing the semantics. u fixed stack size -- the stack of an application is set at execution time and cannot grow during runtime. The default stack size is 4k! It can be increased with the "-s" option of m68k-uClinux-elf2flat. u limited libc compared to glibc -- either add more to libc, or remove some functionality. u no support for ELF binary file format u very limited support for shared libraries due to missing MMU -- all applications get linked statically u mmap() is very inefficient u no paging -- applications have to be loaded completely into RAM, the heap is very susceptible to fragmentation. ======== Annick Fron

Pharo Kernel

Hi, I have donwloaded Pharo-Kernel 12-12229, and I have launched the PharoKernel.image. It comes under Linux with a blank window (where in Windows it is headless). How is it possible to get a real headless kernel on Linux ? Annick Fron
