Portable Object Compiler Description

Portable Object Compiler project consists of a set of Objective-C class libraries and a precompiler (translator) that generates Portable Object Compiler project consists of a set of Objective-C class libraries and a precompiler (translator) that generates plain C code.Here are some key features of "Portable Object Compiler":· Easy to install or to modify.· Works on many systems with the native cc, debugger, profiler etc. (Unix, Windows, Macintosh, Beos, OpenVMS etc. see Platforms.txt file)· Option for reference counted memory management (-refcnt). This uses the native malloc(), free() etc. but the compiler generates statements for keeping track of references (Tested on a few platforms, such as IRIX 5.2 with the SGI malloc).· Built-in possibility of tracing Objective C messages. (OBJCRTMSG)· Straightforward "C" messenger; "inline cache" messenger. Forwarding C messenger (to support -doesNotUnderstand:).· All classes get a +initialize message at start-up, rather than 'each class receives a +initialize before it receives its first message'.· Some support for translating Objective-C to Smalltalk (-st80 option)· Automatic archiver. Compiler generates code for classes to save and load objects to and from disk (for all instance variables of type "id").· Option for Garbage Collection (using Boehm gc package). Tested on some UNIXes and WIN32. Option for reference counted memory management (doesn't require Boehm).· Exception handling scheme (using Objective-C Blocks) that allows to specify a default handler to be executed.· Supports dynamically loading Objective-C modules on Windows, FreeBSD, HP-UX, Linux, IRIX, Digital Unix etc.· Has a switch for double indirection for Object identifiers (id as a handle instead of a pointer). (-become: method)· Supports forwarding messages (-doesNotUnderstand: method)· Support for Embedded SQL in Objective-C (Informix only for now) · Great system for experimentation with your own additions/extensions to Objective C !Requirements:· Obtain a copy of 'gcc' or use the C compiler 'cc' of your specific system (depending on the system you use, the native 'cc' may be better or worse than gcc) · Compile flex-2.5.4 if you don't have flex; don't use lex · Compile BSD byacc 1.9.1 (and install as 'byacc', bison could be used as alternative, but I recommend byacc) · Install objc-bootstrap-3.2.8.tar.gz (install this package before you install objc-3.2.8 !!) · Install objc-3.2.8.tar.gz. · Optionally, for the class browser, install cursel-0.2.2.tar.gz.X11Blocks-0.0.1.tar.gz is a library (under development) for · X11 development based on the Objective-C blocks concept.
