TTF_Openfont not found

[mhinsch]

The included example crashes for both, Julia 0.6.4 and 0.7 beta 2 on the call to TTF_Openfont:

ERROR: LoadError: UndefVarError: TTF_OpenFont not defined
Stacktrace:

 [4] _start() at ./client.jl:371

libsdl2-ttf and libsdl2-ttf-dev are installed. The platform is ubuntu 16.4.

Thanks for testing this out, we have been making some changes recently (https://github.com/jonathanBieler/SimpleDirectMediaLayer.jl/pull/20) and it might work better on master (Pkg.checkout) although the tests still fail on linux (installation problems...).

Note there's this issue on v0.6 that might also create problems.

With master I don't get a LoadError any more, but now the test program crashes with a segfault on what appears to be this line:

text = SDL2.TTF_RenderText_Blended(font, txt, SDL2.Color(20,20,20,255))

(again the same for 0.6.4 and 0.7 beta 2 (plus a gazillion warnings for the latter of course))

I've in the meantime upgraded to 18.4 (new computer). Installing master and running tests and examples works without any issues now.

Edit: File this one under great stupidity. It turns out the problem (of example in master crashing) was due to me copying the script into a separate directory which meant that it didn't find the font file any more... So, unless lack of return value checking in the example program is considered a bug please feel free to close this issue.

Nice, I also made some changes on master to make sure everything installs, so I don't think the issue was useless.
