====== Writing your own plugins, CLI and Netbeans Setup (Windows) ======

You dont need to compile avidemux yourself to write your  own plugins.\\
What you need is :
  * Avidemux installed on your system
  * SDK component activated
  * CMake > 3.x and mingw64-32 or 64 installed [[https://cmake.org/download/|CMake]]
  * Msys2 installed [[https://sourceforge.net/p/msys2/wiki/MSYS2%20installation/|MSYS]]
  * Mingw64 installed [[http://mingw-w64.org/doku.php/download/mingw-builds|MinGW64]]
  * A demo/sample video filter, available here {{  :build:videofilterdemo_2.7.zip |}}

== SDK ===
Make sure you have selected the SDK component during install

{{:build:sdk1r.png?200|}}

== Msys2 and Mingw64 setup ===

{{:build:mingw64_setup.png?200|}}

It is a good idea to use a short path, i.e. c:\MingW64 and c:\msys64
Make sure you have them both in your path (i.e. c:\Mingw64\mingw64\bin and c:\msys64\usr\bin)

== Cmake ==

You will need to install cmake version 3.x\\
__Make sure the cmake "bin" folder is in your path __\\


----

====== Cli : Compile the sample using MSYS2/MinGW ======

It is best to start here to make sure you have a working environment

Start a MSYS2 shell, go where you unzipped the demo code (i.e. c:\tmp\videoFilterDemo for example )\\
Create a build folder
   mkdir build && cd build
then generate the makefile
   cmake -G "MSYS Makefiles" -DCMAKE_MAKE_PROGRAM=mingw32-make -DCMAKE_INSTALL_PREFIX="c:\Program Files\Avidemux 2.6 - 64 bits" ..
   
__The CMAKE_INSTALL_PREFIX should point to the place where avidemux is__

Look for error, it should go without problem.\\
   make
Upon success, copy the dll in    c:\Program Files\Avidemux 2.6 - 64 bits\plugins\videoFilters\ \\
Start avidemux and you should see a logo_sample filter in the menu list

**Important/Common problem**
----

If the C++ library used by mingw is more recent than the one used by avidemux itself you'll run into two problem :

  * If you have error undefined symbol _imp_xxxxstdcxx11xxxxbasic_stringxxx when compiling , add one line at the very top of CMakeLists.txt
   ADD_DEFINITIONS(-D_GLIBCXX_USE_CXX11_ABI=0)
  * If you have error at startup "Cannot locate xyz in libsdtc+++", Overwrite the libstdc++-6.dll in the avidemux folder with the one from mingw, e.g. c:\Mingw64\mingw64\bin\libstdc++-6.dll

Do the fixes above, erase the build folder (build/*) and do it all over again (it takes 5 sec)


----
====== Using Netbeans ======

You'll need the same requirement as above (i.e. cmake, msys,...)\\
You *MUST* add msys make, mingw make will not work with netbeans\\
Open a msys2 shell, and enter\\
   pacman -S make  
   

== Configure Netbeans ==


There are two parts :
  * Configure the toolchain
  * Configure the project

The toolchain should be configured as follow :\\
{{:build:netbeans_toolchain.png?200|Toolchain}}\\
The important part is to select the make from msys64/usr/bin


Everything is coming from msys, the screenshot is a bit old

Last step is to setup the project :\\ 
{{:build:netbeans_project1.png?200|Step 1}} \\
{{:build:nb_2.png?200| Step2}} \\
{{:build:nb_5.png?200|Step 3}} \\

The important part are :
  * At step2 select custom
  * At step3, add \\


 -G "MSYS Makefiles" -DCMAKE_INSTALL_PREFIX="c:/Program Files/Avidemux 2.6 - 64 bits""

Note that the path separator are "/" and not "\"!

{{:build:sdk_netbeans_cmake_option.png?200|}}

You can build the sample now.

In case you made a mistake, dont forget to delete the CMakeCache.txt file before retrying
