GLTB

(also known as Gregor's little toolbox)

About

The GTLB is a small C++ library of helpful code that I keep reusing across multiple projects. It is open source under a BSD license. The code covers many areas, including

• memory management: internal reference counting including weak pointers
• multithreading: threads, mutexes, rw locks, a simple but flexible job queue
• geometry: various data types and algorithms for 2d and 3d geometric primitives (lines, triangles, spheres...)
• machine information: query information about available processors, free/total memory, your process etc. in a platform-independent way
• logging: a simple and lightweight logging framework
• atomic operations: atomic operations on plain variables (for cases when std::atomic is not helpful)

The currently supported platforms are

• Microsoft Windows XP and newer with Visual Studio 2012 and newer
• Linux and Android with GCC 4.7 and newer

Older compilers might work but are not tested. The library uses some C++ features which may not be supported on older compilers than the ones listed above.

It should be a rather simple matter to port GLTB to MacOS and iOS, but due to lack of access to the proper hardware this has not yet been done.

Status

Although the library has been used in quite a lot of different situations and quite stable, it is not yet well documented. However, most of the code is rather simple, but tedious platform abstraction and should be easy to understand.

Download

The library is distributed only in source code form. You will have to compile it yourself. The necessary cmake scripts are included.

• Release 1.0.0 (initial release)
