etesync-dav fails to build on Linux Mint

[lord-aerion]

Hi,

I've successfully installed etesync-dav on Arch Linux, but I'm having trouble getting it installed on Linux Mint 18.3.

I get the following error when running pip install etesync-dav

Any ideas?

Please let me know if you need further information from me.

Kind regards, Emile

Radicale and etesync are Python 3 only. It looks like you're using python2. If that's the case. Please use python3 and close this.

Thanks!

[lord-aerion]

Both python2 and python3 are installed.

[tasn]

Run "python3 setup.py" ?

[lord-aerion]

Do you mean downloading the zip from GitHub and installing that, instead of trying to install it using pip?

[tasn]

Ah, I thought you were trying to install from pip. If you are installing from pip, use pip3 rather than pip.

[lord-aerion]

I was indeed trying to install from pip. As you can probably tell, I'm not very familiar with python. I'm an admin person, not a developer, so please excuse my ignorance! :-)

After installing and using pip3 I do indeed get a lot further, however running sudo pip3 install etesync-dav now fails with a different error:

Due to my lack of knowledge of Python I've not been able to follow the recommendation to install etesync-dav in a python virtualenv.

[tasn]

It looks like you need to install python3-dev or some sort of a package like this. I don't really know how it is on mint.

[lord-aerion]

That was indeed the correct package. I also needed libssl-dev. I've now successfully installed it.

Thank you for your time and effort!

[tasn]

Pleasure. Could you please open a PR against the readme with instructions for mint, or alternatively let me know the list of packages you used so I can add it myself?

Thanks.
