Python - Unable to install matplotlib

[cswl]

I am unable to install matplotlib.
I already have installed latest libfreetype and libfreetype-dev.But it still errors out on freetype,

I am running Debian testing on my machine. Python is latest 3.5.b3 compiled from source and in virtual env , running the command :

pip install matplotlib

gives following error.

...... freetype: no [Requires freetype2 2.3 or later. Found ...] png: yes [version 1.2.50] ..... ..... * The following required packages can not be built: * freetype ....

Full error log here: http://pastebin.com/4N6de3Vw/
I do not understand why requirement is not marked for compilation even though found,

Can't you just install it from the repositories?

https://packages.debian.org/search?keyw ... ection=all

I've never used matplotlib so excuse me if I'm talking nonsense here.

Yes. I'm aware of the python-matplotlib in the repos.
But I am using Python version 3.5b3 in virtualenv, so I kinda have to have to compile from source.
And Its alright, one thing about debian is you can apt-get anything,

This also happens on latest source from github.
So there must be something going wrong with the way freetype is being detected.

Checking into setup.py now.

The problem still happened on latest github sources. so I checked into setup.py and found the problem.

Apparently, matplotlib was checking for freetype version by using " freeetype-config --ftversion" . But running that command in terminal gave " .." which matplotlib was incorrectly interpreting. I removed the check and hardcoded the freetype version and did setup.py build. And it worked!

man freetype-config says.
--ftversion Return the FreeType version number

I think it must be issue with freetype-config? Can you please test the command to be sure?

Er, I'm in Arch at the moment (and seeding so I can't leave) so this may not be useful:

Code: Select all

empty@Arch ~ % freetype-config --ftversion
2.6.0

Oh, I see. Well, arch always has the latest versions
On my debian testing I'm getting this.

Code: Select all

cswl:~/> freetype-config --ftversion
..
cswl:~/> apt-cache policy libfreetype6
