#include <zbar.h> 1 error generated when running pip install zbar

I'm trying to run pip install zbar and for some reason I can't seem to find an answer to solve this dependency issue. Any help would be extremely appreciated. See traceback below:

I encountered this issue recently while attempting to launch a service locally from Mac OS in a virtual environment, that imports zbar in the python application. The service was still running python2.7.

Having the service running in a virtual environment I was unwilling to attempt anything that required global system changes.

I solved it by having to install zbar through Homebrew (globally). Then exporting flags or implicit rules used in the C compiling "recipe" to the virtual environment. Finally I installed a similar library to the zbar dependancy in the virtual environment.

$ brew install zbar

Then when sourced in the virtual environment I do the following to change the implicit rules in the c compilation recipe:

$ export LDFLAGS="-L$(brew --prefix zbar)/lib"
$ export CFLAGS="-I$(brew --prefix zbar)/include"

Finally I install a light version of zbar inside the venv:

$ pip install zbarlight

After the above, with the additional dependancy of pyzbar below included in my requirements.txt I am able to import zbar with python2.7 in the virtual environment.

pyzbar==0.1.7

Testing the import in the virtual environment:

$ python
>>> import zbar
>>>

Hope this helps someone in the future. I struggled quite a bit in getting this to work and resources regarding zbar are fairly scarce.

In my case I was running Ubuntu and had to install libzbar-dev package:
sudo apt-get install libzbar-dev

Encountered this problem again after 2 years... this is what worked for me

LDFLAGS=-L/usr/local/lib/ CPATH=/usr/local/include/ pip install zbar

$ brew install zbar

and after that

$ pip install zbar

The header files will then be found (zbar.h)

In case others run into this issue aren't able to use pip to install zbar for python:

Install zbar: brew install zbar

Install PIL: brew install pillow

Download zbar source: https://pypi.python.org/pypi/zbar

Unzip zbar: tar -xjvf zbar-0.10.tar.bz2

Install: python setup.py install --user
