[code小心得]DirectFB 1.7 x86 on ubuntu

日期：

大家好  

這次紀錄一下關於在 ubuntu 12.04上面跑 DirectFB  1.7

DirectFB  這個套件，很多裝置上都有用到。最多的大概是在player上巴。



先用apt指令  把x11和 png  jpeg font的相關lib補足

sudo apt-get install libpng12-dev libjpeg62-dev libfreetype6-dev libsysfs-dev libsdl1.2-dev x11proto-xext-dev libxext-dev


接著把linux-fusion裝起來
wget http://www.directfb.org/downloads/Core/linux-fusion/linux-fusion-9.0.2.tar.gz 
tar -xvf linux-fusion-9.0.2.tar.gz 
cd linux-fusion-9.0.2 
make 
sudo make install
接著把DirtectFB 裝起來 這邊使用1.7 version，且安裝到/opt/dfb路徑，x11必要因為環境關係

 wget http://www.directfb.org/downloads/Core/DirectFB-1.7/DirectFB-1.7.0.tar.gz 

 tar -xvf DirectFB-1.7.0.tar.gz 
cd DirectFB-1.7.0 
./autogen.sh --enable-multi --enable-one --enable-network --enable-sawman --enable-fusionsound --enable-fusiondale --enable-x11 --with-graphicsdrivers=none --prefix=/opt/dfb 
make 
sudo make install
要使用之前，先將相關環境變數補上

export LD_LIBRARY_PATH=/opt/dfb/lib/ 
export PKG_CONFIG_PATH=/opt/dfb/lib/pkgconfig/ 
export PATH=/opt/dfb/bin:$PATH
配置x11的環境

 
cat > ~/.directfbrc <<EOF 
mode=1024x768 
pixelformat=ARGB
system=x11 
wm=sawman 
EOF
可以設定利用udev的幫助每次開機時自動掛載fusion節點，或是

 每次使用時再，自行modprobe driver 例如下方所示
sudo depmod -a 
sudo modprobe fusion 
sudo modprobe linux-one
先執行 dfbinfo 看看是否正常

dai@dai-VirtualBox:/opt/dfb/bin$ sudo ./dfbinfo

接著去安裝DirectFB的sample code

 下載  解壓縮後
./configure  --enable-x11  --prefix=/opt/dfb
make
sudo make install
就可以嘗試run 看看範例囉

執行的企鵝範例 sudo  ./df_anti  顯示如下
