ubuntu 编译zbar 静态库

wget http://downloads.sourceforge.net/project/zbar/zbar/0.10/zbar-0.10.tar.gz

tar -zvxf zbar-0.10.tar.gz
sudo apt-get install python-gtk2-dev
sudo apt-get install libqt4-dev
export CFLAGS="-fPIC" #这句话很关键，不然会出现这种错误：relocation R_X86_64_32 against `.rodata' can not be used when making a shared object; recompile with -fPIC

./configure --prefix=/work/oop/zbar --enable-shared=yes --without-imagemagick -disable-video -without-qt -without-gtk -without-x
