+Introducing the Open Watcom Compilers
+=====================================
+
+Jeffrey Armstrong
+
+https://github.com/open-watcom
+
+25 October 2014
+
+.. note::
+
+   * Ask who cross-compiles
+
+Introduction
+============
+
+.. rst-class:: build
+
+* C, C++, and Fortran 77 Compilers
+* Runtime Libraries
+* Assembler
+* Make Utility
+* Integrated Development Environment
+* Text and Graphical Debuggers
+
+.. note::
+
+    * Introduce compilers, but then say "so much more"
+
+History
+=======
+
+* Originally commercial
+ * Popular during MS-DOS's heyday
+* Released as "open-source" in 2003
+
+.. note::
+
+    * Explain license
+
+History
+=======
+
+* 2003 - Sybase releases OW as open-source
+* 2003 - Ensure OW builds itself
+* 2005 - x86 Linux support added
+* 2009 - Independent Windows API implemented
+* 2012 - 2.0 fork begins
+ * x64 support
+ * Improved C99 support
+ * Work towards complete STL
+
+Compiler Capabilities
+=====================
+
+.. rst-class:: build
+
+* x86 (and recently x64) Code Generators
+ * 16-bit, 32-bit, and 64-bit
+* Some limitations on C++ compiler
+* Complete support for fixed-format Fortran
+* Cross-compiling
+
+Compiler Capabilities
+=====================
+
+.. rst-class:: build
+
+* Supported hosts/targets:
+ * MS-DOS / Windows3.x / Win32
+ * Windows NT
+ * OS/2
+ * Netware :sup:`1`
+ * x86/x64 Linux
+ * RDOS :sup:`1`
+
+:sup:`1` Target only
+
+Compiler Architecture
+=====================
+
+* Language-specific front end
+* Architecture-specific back end
+* Single executables
+ * No intermediate files 
+
+C Runtime Libraries
+===================
+
+* Independent implementations
+* C89 complete
+* Partial C99
+* Common "legacy" extensions
+
+C++ Runtime Libraries
+=====================
+
+* C++98 mostly complete
+* Independent STL implementation
+ * About 50% complete
+* Supports 16-bit compilers
+
+Fortran Runtime Libraries
+=========================
+
+* Complete Fortran 77 intrinsic support
+* Odd Open Watcom extensions
+* No Cray pointer support
+
+Make Utility
+============
+
+* Complete "make" utility
+* File-based
+* Works on all supported hosts
+
+.. note::
+
+    * Useful for DOS and Windows developers 
+    
+Integrated Dev Environment
+==========================
+
+* Cross-platform IDE
+ * Supports Win3.x/9x, OS/2, WinNT
+* Ugly but functional
+* Some interest in GTK+ port, but...
+
+.. note::
+
+    * Mention port can't proceed because of a shortcoming
+    
+Debuggers
+=========
+
+* Text-mode on all supported hosts
+* GUI on Win3.x/9x, OS/2, WinNT
+* Supports DWARF, CodeView, and Watcom debugging symbols
+
+Project Summary
+===============
+
+* Substantially complex
+* Complete development toolchain
+
+Performance
+===========
+
+Whetstone - C
+
+Performance - MDBNCH
+====================
+
+Performance - Building Python
+=============================
+
+
+
+Shortcomings
+============
