Compiling FreeType on Android using Termux

If you want to test FreeType on arm devices, compiling it on an Android phone is one of the easiest ways.

1. Compiling FreeType

1. Install and open termux

2. Update termux packages using:

   pkg update
   pkg upgrade
   

   Select y if any configuration changes are asked

3. Install git:

   pkg install git
   

4. Install packages required for compilation:

   pkg install automake autoconf libtool make clang binutils
   

5. Clone FreeType's git repository:

   git clone https://gitlab.freedesktop.org/freetype/freetype.git
   

6. Enter into the source directory:

   cd freetype/
   

7. Now you can compile FreeType according to INSTALL_UNIX.md:

   ./autogen.sh
   ./configure
   make -j$(nproc)
   

   The compiled binaries can be accessed under objs/.libs

2. Compiling FreeType Demo programs

If you need to test your changes you may want to use ft-demo programs. They can be compiled and run by follwing these steps:

1. First compile FreeType using the steps above.

2. Clone FreeType demos adjacent to the freetype/ directory:

   git clone https://gitlab.freedesktop.org/freetype/freetype-demos.git
   

   i.e. If you can access FreeType repo under ~/freetype, you should be able to access ~/freetype-demos.

3. Enter into the ft-demos directory:

   cd freetype-demos
   

4. Compile the programs:

   make
   

5. The compiled binaries can be accessed and executed under bin/ like:

   cd bin
   ./ftlint
