Unable to set up dev enviroment on Debian 8.5

[markotikvic]

Hi,

I'm getting some (what I assume to be linking problem) errors when trying to run limeqml. I was trying to start contributing to the backend section but that's not gonna happen if I don't set up my machine correctly (:
This is my current setup:
go version go1.6.2 linux/amd64
GCC/G++ 4.9.2
Python 3.5.2

Now, since Python 3.5 isn't in the Debian repos at the moment I went and installed it from source (btw, that's what I think is the problem). I'm not a python guy so if any of the python gurus could help sort this out so I can GO (get it? GO!? no? okay, bad pun...) and get started with contributing.

I followed the instructions from here https://github.com/limetext/lime/wiki/Building-on-Debian-Stretch
but the 'go build' fails for the /lime-qml/main with these lovely messages:

marko@debian:~/workspace/go/src/github.com/limetext/lime-qml/main$ limeqml

Now, as I mentioned, I get that most of these are caused by "failed to link dependencies" with python but the one in capi.cpp seems like a dev mistake. Anyway, any help would be appreciated and let me know if you need some other information.
Thanks,
Marko.

The first issue is related to the qt version also mentioned limetext/qml-go#4.
I'm not sure about the python issue but #1 seems similar.

[markotikvic]

I'll try the solution for the #1 tomorrow but it looks pretty promising.
Thanks.
