Unable to execute pip install python-lzo on Ubuntu 16.04 virtualenv

I am trying to install the python-lzo package on a virtualenv, yet it keeps on failing with the following error log

I have looked up for the file lzo1x.h and it looks like it doesn't exist.
Any idea what might be going wrong?

Do you have zlib1g-dev installed? apt install zlib1g-dev. That is a C library, not a python one, and it provides that actual LZO implementation that python-lzo wraps around.

[francotestori]

Yes, I already have zlib1g-dev package installed; and the error that appears is the one I have already posted. This happens while trying to perform pip install python-lzo

[jdonners]

this is because lzo1x.h is actually located in lzo/lzo1x.h. A workaround is to download the package, untar, modify the .c-file, tar and install the local file. I'll try to create a pull request.

[jd-boyd]

@francotestori, I merged @jdonners pull request. Can you confirm that it also fixes your issue? THank you very much.

Extra package that was required to get this working on Ubuntu 16.04: liblzo2-dev
This packages includes the lzo1x.h file located at: /usr/include/lzo/lzo1x.h

[jd-boyd]

OK, stupidly I never outline what packages needed installed on ubuntu before trying to install python-lzo. I've now updated the README with that here: #34

I'm going to close this now since the original person never confirmed if it worked for them or not. Additional comments should be in new issues.

Thank you all
