boost static assert error is thrown during compilation

[emericg]

Hi! I was trying to build libcec-daemon on my Archlinux (using libcec 2.1.4 and boost 1.55) but I face a very weird build error (a boost static assert is thrown):

erreur: static assertion failed: Target type is neither std::istream`able nor std::wistream`able

It has something to do with the HDMI::address type. Any idea where that might come from ? Thanks!

Here is the full log:

Andrew,

Not sure if you see this email directly. Thank you for the speedy response, now compiles perfectly on Ubuntu 14.04. Took a while to realise that the -p 1 flag was needed or daemon closed down, but got there.

Is there any way to use the daemon to send events TO the TV ? All I want to do is turn on TV and set correct HDMI port on mythfrontend startup. If not do you use cec-client as a single shot ?

best regards,

John

By the way the fix works great, thank you!
