Lgi

About

LGI is an open source GUI framework (on Github) for abstracting out all the operating system dependencies that you can produce portable code. It handles all the graphical interface functions, threading and semaphores, network connectivity and lots of other bits and peices to help build small, fast and reliable applications.

The strengths of LGI is that it's a small enough library that one person can understand it all. Also it's not too much of a burden on an application, both in increased download time and memory footprint. LGI at the moment compresses to about 519 KiB, which while not insignificant is quite a bit smaller than the other options.

Ultimately however size is a secondary consideration to the core feature of LGI and that is portability. Currently 3 serious ports exist: Win32, Mac and Linux. There is also a legacy Haiku/BeOS port which is unsupported.

I have completed some basic documentation for the library and scripting language, and there are a number of apps with source code available on github.

Ports Status

Ordered by maturity:
  • Win32/64 (Win7/Win8/Win10)
    This is the most stable and featured port, as it's the plaform I use the most. Everything works in Windows, and it's the fastest due to the speed of the Win32 Graphical Subsystem. I no longer support or test on any version of windows before XP. The GTK port also works on Windows and you can compile with MingW as well.
  • Mac OS X (>=10.9)
    Stable port of Lgi using the Carbon API. Contains pretty complete functionality. There is work going on to support Cocoa/64bit builds as of late 2018.
  • Linux/Gtk+ (Ubuntu >= 14.04)
    This port to Gtk2 and Posix is stable. Runs on both x86 and ARM instruction sets. There is also the ability to build the GTK port under other OS's like Windows.
  • SDL
    The SDL port has some GUI functionality. It's not used much. Font support via Freetype2.
  • Haiku (BeOS)
    The BeOS port has been updated to run on Haiku however due to that platform being extremely slow and having issues with disk corruption I'm not persuing it anymore.

Features

Building LGI

First check out the source:
git clone https://github.com/memecode/Lgi.git Lgi/trunk

Windows

Support Libraries

For full graphics and charset support download (or check you already have) iconv, libpng and zlib, libjpeg; then add their include paths to your compilers include paths. Or find the defines in Lgi.h for the various libraries and set them to 0.

Visual Studio 2013

Install a supported version of Visual Studio. Build the appropriate workspace:
  • vs2013: Lgi_vs2013.sln

Adding build folders to the shared library path:

Add this to your path:
  • ./Lgi/trunk/lib

Mac

Install XCode

Go to the Apple Developer site and grab XCode

Build

Open Lgi.xcodeproj in XCode and run the build command.

Linux

Building on Ubuntu:
sudo apt-get install git libmagic-dev libgtk2.0-dev libgstreamer1.0-dev
git clone https://github.com/memecode/Lgi.git Lgi/trunk
cd Lgi/trunk
ln -s Makefile.linux makefile
make -j 4
If the makefile doesn't work on your system:
  • Download a binary of LgiIde
  • Project->Open and select Lgi/trunk/Ide/LgiIde.xml
  • Project->Create Makefile->Linux
  • Project->Build
History:
A bunch of very old builds. For anything current you should use the git repositry:
