linux build failing...

[rorywalsh]

Hi Jules, I just tried the last master and develop branch on Linux without any success. Looks like I have all the dependencies I need: 

rory@rory-MS-7B17:~/sourcecode/choc/tests/build$ cmake ..

But when I build I get hit with lots of these errors:

Perhaps there is a quick fix for this?

[julianstorer]

I've no idea - probably you've just got an old version of webkit, and need to update it? GCC 9 is pretty old.

[rorywalsh]

Ok, thanks Jules, I had assumed the Cmake script was checking that my dependencies were up to the task. I'll post back if I find the solution.

[rorywalsh]

So my version of webkit was Ok, but I needed to update libjavascriptcoregtk. I'm up and running now. Sorry for the noise. :+1:

[julianstorer]

Glad you figured it out. For "how to" stuff like this, maybe our discord channel would be a better place to ask
