1. Build DirectFB-1.6.0
Thư viện phụ thuộc
- libpng
- freetype

 # toolchain
 export PATH=$PATH:/opt/FriendlyARM/toolschain/4.4.3/bin  
 export CROSS=arm-none-linux-gnueabi-  
 export HOST=arm-none-linux-gnueabi
 
 #thư viện phụ thuộc   
 DEPEND_LIB_DIR=/friendlyarm  
 export CFLAGS=-I${DEPEND_LIB_DIR}/include  
 export CPPFLAGS=-I${DEPEND_LIB_DIR}/include  
 export LDFLAGS=-L${DEPEND_LIB_DIR}/lib  
 export PKG_CONFIG_PATH=${DEPEND_LIB_DIR}/lib/pkgconfig  
 export LD_LIBRARY_PATH=${DEPEND_LIB_DIR}/lib  
 export PATH=$PATH:${DEPEND_LIB_DIR}/bin:${DEPEND_LIB_DIR}/sbin  
   
 #cấu hình 
 export PREFIX=/friendlyarm  

 ./configure --prefix=${PREFIX} --host=${HOST} \  
 --disable-x11 --enable-fbdev=yes --disable-devmem \  
 --with-gfxdrivers=none --with-inputdrivers=none  \
 CC=${CROSS}gcc

 #compile
 make
 make install
   

2. Build DirectFB-examples-1.6.0

 # toolchain  
 export PATH=$PATH:/opt/FriendlyARM/toolschain/4.4.3/bin  
 export CROSS=arm-none-linux-gnueabi-  
 export HOST=arm-none-linux-gnueabi  
   
 # thu vien phu thuoc: directfb
 DEPEND_LIB_DIR=/friendlyarm/directfb  
 export CFLAGS=-I${DEPEND_LIB_DIR}/include  
 export CPPFLAGS=-I${DEPEND_LIB_DIR}/include  
 export LDFLAGS=-L${DEPEND_LIB_DIR}/lib  
 export PKG_CONFIG_PATH=${DEPEND_LIB_DIR}/lib/pkgconfig  
 export LD_LIBRARY_PATH=${DEPEND_LIB_DIR}/lib  
 export PATH=$PATH:${DEPEND_LIB_DIR}/bin:${DEPEND_LIB_DIR}/sbin  
   
 #config  
 export PREFIX=/friendlyarm/directfb  
 ./configure --prefix=${PREFIX} --host=${HOST} \  
 CC=${CROSS}gcc  
   
 make  
 make install  

3. Build Directfb application
df_matrix.c là một ví dụ được lấy ra từ gói DirectFB-examples-1.6.0

 export PATH=$PATH:/opt/FriendlyARM/toolschain/4.4.3/bin  
   
 DEPEND_LIB_DIR=/friendlyarm 
 export PKG_CONFIG_PATH=${DEPEND_LIB_DIR}/lib/pkgconfig  
 export LD_LIBRARY_PATH=${DEPEND_LIB_DIR}/lib  
   
 arm-none-linux-gnueabi-gcc df_matrix.c -o df_matrix  $(pkg-config --libs --cflags direct directfb directfb-internal)  

4. Chạy thử app directfb trên board
Chúng ta sẽ chạy thử các app đã build ở mục 3

- copy tất cả các lib và example xuống board (sdcard or mount NFS)
- export biến môi trường

 DEPEND_LIB_DIR=/friendlyarm  
 export CFLAGS=-I${DEPEND_LIB_DIR}/include  
 export CPPFLAGS=-I${DEPEND_LIB_DIR}/include  
 export LDFLAGS=-L${DEPEND_LIB_DIR}/lib  
 export PKG_CONFIG_PATH=${DEPEND_LIB_DIR}/lib/pkgconfig  
 export LD_LIBRARY_PATH=${DEPEND_LIB_DIR}/lib  
 export PATH=$PATH:${DEPEND_LIB_DIR}/bin:${DEPEND_LIB_DIR}/sbin  

- chạy thử các app

 $ cd /friendlyarm/directfb-1.6.0-exam/bin  
 $ ./df_andi
