Product Description:

macstl is a C++ source library designed to bring the Macintosh into the world of modern generic programming. The cornerstone is a fast valarray optimized for Altivec: it runs 3.9x - 18.2x faster than gcc 3.3 libstdc++ and 5.2x - 16.2x faster than Metrowerks MSL C++. Developers unfamiliar with Altivec can write to a portable, intuitive and standard component, and just flicking a single compiler switch will make it run fast on a G4 or G5, or run correctly on other non-Altivec systems.

The Mach copy-on-write vector is a partial specialization of std::vector for the Mach allocator. It neatly uses the OS vm_copy facility to "get around" thread safety issues when doing copy-on-write and reference counting. As a result, std::vector can be copied, passed back by value and enlarged without the same overheads.

What's new in this version:

Now builds with Xcode 1.0.
Fixed altivec functions not compiling in gcc 3.1: "tree_list not supported by dump_expr".
Reduced download size by removing build directories.
Fixed altivec abs ambiguity.
Fixed internal valarray #includes.
Fixed uninitialized_copy_n not compiling with non-random access iterators.

Operating System Requirements:

This product is designed to run on the following operating systems:

Mac OS X 10.3
Mac OS X 10.2

Additional Requirements:

Mac OS X 10.2 or higher
Jaguar Project Builder 2.0, Metrowerks Codewarrior 9 or Panther Xcode 1.0 or better

I mean, it's a complex library, but come on...

Out of the box, it doesn't work with PB on 10.2. The compilers are hard coded into the project (see Target -> Settings -> Expert View) to use GCC 3.3. Default for 10.2 is GCC 3.1.

Compiling also generated a lot of warnings:

internal/valarray_indirect.h:219: warning: Invalid skip header index count.
internal/valarray_indirect.h:219: warning: Indexing information is not generated properly.

Having fixed these, it compiled and ran the tests just fine.
