assuming you're using a debian derivative (like ubuntu), you need to install zbar
's developement package, which contains the header file zbar.h
$ sudo apt-get install libzbar-dev
for redhat/fedora systems:
$ sudo yum install zbar-devel
and probably python's dev package too:
$ sudo apt-get install python3-dev
