This repository contains the external dependencies needed to build full asynchronous, networking and video support for the simh simulators on Windows.

It contains five separate packages which the windows simh build depends on: The WinPcap developer Pack Posix threads for Windows Simple DirectMedia Layer Simple DirectMedia Layer True Type Fonts Perl Compatible Regular Expressions

The Visual Studio Projects in the simh source tree presume that The directory containing this file should be located parallel to the directory containing the simh source code. The makefile which can be used by MinGW compiler also presumes the same directory structure.

For Example, the directory structure should look like:

.../simh/simhv38-2-rc1/VAX/vax_cpu.c
.../simh/simhv38-2-rc1/scp.c
.../simh/simhv38-2-rc1/Visual Studio Projects/simh.sln
.../simh/simhv38-2-rc1/Visual Studio Projects/VAX.vcproj
.../simh/simhv38-2-rc1/BIN/Nt/Win32-Release/vax.exe
.../simh/windows-build/pthreads/pthread.h
.../simh/windows-build/winpcap/WpdPack/Include/pcap.h
.../simh/windows-build/libSDL/SDL-2.0.3/include/SDL.h
.../simh/windows-build/PCRE/include/pcreposix.h

The ../simh/windows-build/winpcap directory contains Version 4.1.2 of the winpcap developer pack from:

   http://www.winpcap.org/devel.htm

The ../simh/windows-build/pthreads directory contains the source to the next release of the pthreads-win32 Posix Threads package for the windows platform.

The ../simh/windows-build/libSDL directory contains the source to version 2.0.3 of libSDL2. This source has been modified from the code in the zip file: http://www.libsdl.org/release/SDL2-2.0.3.zip. The modifications produce SDL libraries which can be statically linked into simh simulator binaries when building with the Microsoft Visual Studio compilers. These binaries will then run without external DLL dependencies. The MinGW link libraries are also provided. These have been extracted from: http://www.libsdl.org/release/SDL2-devel-2.0.3-mingw.tar.gz along with the SDL2.dll file which is required when running a simulator with video support if it is compiled with the MinGW gcc compiler.

The SDL True Type Font support is also modified to produce a static library with the original source from: https://www.libsdl.org/projects/SDL_ttf/release/SDL2_ttf-2.0.12.zip

The ../simh/windows-build/PCRE directory contains the source to PCRE version 8.36 the Perl Compatible Regular Expression library.
