Typically, if the image can still access the change file but not the source file (or the other way around), some methods still show temporary variable names, whereas other methods show t1, t2, etc , depending on which files their sources were in. 2015-01-20 10:21 GMT+01:00 Sven Van

Re: [Pharo-users] Building 64-bit pharo VM

Hello, What you want to do is difficult because the vm internals rely on the word size. There are two solutions: 1) editing the VM (JIT native code back end + memory manager) to support 64 bits. That's a work in progress. You can discuss about it on the Squeak vm-dev mailing list. 2) compiling

Hello, this is possible but non trivial. I think the easiest way is to bind the C functions to manage C libraries: dlopen, dlsym, dlclose, dlerror. Then you can manually open and close the dynamic libs (dlopen, dlclose) and call the function dynamically loaded with dlsym. dlerror is used for
