For someone coming from a windows background, where you do virtually everything, using GUI probably with Visual studio or an equivalent IDE, compiling a program from the command line can be a daunting task. 

This blog post will guide you through compiling and building the popular open source video encoding library on windows using the MinGW(Minimalist GNU on Windows). 

First you need to download the x264 source code from  Or if you know how to use git, you can git clone the x264 from git://git.videolan.org/x264.git. 

Then you should download MinGW from  Download the mingw-get-inst-20111118.exe (591.9 kB) install it and during the installation steps, select all the check boxes. 

After the installation is completed, then from Start button , click All program, then click MinGW and then Click on MinGW shell, this brings up the following window 

 
From the msys shell change your directory to the location where your x264 source code is, in my own case the x264 code is in the c: drive so I will simply Type cd c:\x264

  

Then type ./configure and press enter, this screen waits for some seconds and the bring

  

Then you can now type make and press enter, this will bring up the window below, showing the progress of the compilation process.

  

After the compilation is finished, if you look into your x264 directory you will find x264.exe file there.

  


Now compiling the x264 into a dynamic link library that can be used in Visual studio takes another process entirely. Open the MinGW bash once again and change the directory to the location of your x264 source code, just like you did previously. 
Then type 
./configure --disable-cli --enable-shared --extra-ldflags=-Wl,--output-def=libx264-120.def 
              or just 
./configure --disable-cli --enable-shared --extra-ldflags=-Wl,--output-def=libx264.def

  

Now in libx264-120.def “120” is the version of the x264 you are using, you can find the version of the x264 you are using by opening the x264.h file in your x264 source folder you will see something like this #define X264_BUILD 120 depending on your version.

You can now type the make command and press enter and you will find the libx264-120.dll in your x264 source folder. Then rename libx264-120.dll to libx264.dll and you have you dynamic link library to work with.

  

If you wish to generate the Visual Studio .lib file to work with then open a Visual Studio command prompt, and change the directory to the location of the x264 source . 
Then run this command
 LIB /DEF:libx264.def 
Then press enter 

 

And your libx264.lib would be generated.
