Comment 5 nanikata15 2017-04-30 05:11:25 UTC
The error appears to happen because
Glib::RefPtr no longer implicitly converts to bool with gcc 5.
A simple solution is to explicitly cast it.

I've attached a simple patch demonstrating the solution and confirmed
that both the version in portage and the latest svn version compile
with gcc-5.4.0 

A few words of warning:
1. The portage version JD is outdated and no longer works (segfaults)
with some external textboards.
2. JDs main use case is to browse 2channel,
but because of change in API and policy of the 2channel board,
JD can no longer be used with it without major user intervention,
like setting up a local proxy to scrape the html version of 2channel
and convert it to a format JD understands.
3. Because of the previously mentioned change of 2channel policy,
the author of JD stated that the requirements to use the new API
are incompatible with open source, therefore there is very little chance
JD will work with 2channel again. Development also seems to have stopped.
4. JD is still fully usable with other boards,
but for some of them a newer version than what is available in portage is needed.
