Compilation

Windows

Preparations

Use visual studio 2013 or later version

• *.sh Error
  A shell executor, i.e. the bash in git for windows, is needed and should be found in PATH variable. For example, the path C:\Program Files\Git\bin can be added if git-for-windows is installed.

• yasm Error
  vsyasm is needed and 1.2.0 is suggested for windows platform. It can be downloaded through: http://yasm.tortall.net/Download.html . A later version 1.3.0 (unofficial revision, please read the instructions of yasm to build it for your work), can be found in https://github.com/luofalei/yasm/tree/vs2013 .

The installation of vsyasm is as follows (if you were using VS2013):

(1) Copy `vsyasm.exe` to the following directory, 
    "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\"
(2)	Copy the other 3 files in `vsyasm` to the `MSBuild template` directorty, as follows, 
    "C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V120\BuildCustomizations\"
(3) Re-open the solution. 

Compilation

1. Opendavs2/build/vs2013/davs2.sln with VS2013（or later version）
2. Set davs2 as start project
3. Compiling

Linux

Preparations

dAVS2 needs support of a series of libs under Linux. Lib asked while compiling should be installed.

Compilation

1. Step into davs2/build/linux
2. Run ./confiugre with compile options
3. Run make
4. Run make install (optional)
