# Visual C++ 2008 project files #
#################################
There are two solution files for Visual C++ 2008:
Using Microsoft Visual C++ 2008, you can build the Win32/MFC and the Win32/Qt build.
Refer to the instructions below for further assistance:
===Win32/MFC===
The Windows MFC GUI version project files are located in trunk/project/vc2008_mfc (VBA2008.sln).
In order to compile it, you have to compile or download a precompiled version of zlib and libpng first
and set your compiler's INCLUDE and LIB path accordingly.
You also need Microsoft's DirectX SDK (At least for DirectInput).
This is the full-featured Windows build using the MFC GUI.
The project files are located in trunk/project/vc2008_mfc (VBA2008.sln).
Before you can compile it, you have to take care of some prerequisites:
Download the zlib & libpng sources from the internet and extract them both to the same folder.
Rename them so you have a folder called libpng and another one called zlib in the same loaction.
Open libpng/projects/visualc71/libpng.sln. Let the assistant convert them if necessary.
Build the "DLL Release" & "DLL Debug" configurations.
Set up your operating system's PATH variable to point to the created zlib & libpng DLLs.
Set up your compiler's LIB & INCLUDE paths to point to the created lib files and the source files.
You also have to install Microsoft's DirectX SDK for DirectInput & XAudio2.
If you want to enable OpenAL sound output, install the OpenAL SDK. If you do not want it, #define NO_OAL.
Some pixel filters come with assembler code compatible with NASM syntax.
Extract NASM somewhere and add it to your compiler's PATH environment variable.
All .asm files should be handled with the "nasm.rules" build rules file.
Some pixel filters come with assembler code, which compatible to the NASM syntax.
Extract NASM somewhere and add it to your compiler's executable file paths.
All .asm files will be handled with the "nasm.rules" build rules file which comes with this project file.
===Win32/Qt===
The MS Visual C++ 2008 Express-compatible project file can be found in trunk/project/vc2008_qt.
