sigil 0.6.0 will not build against boost 1.65.1 error: use of undeclared identifier '_1'

[kencu (Ken)]

sigil fails to build against the new boost update 1.65.1 on both highsierra and on 10.6.8/libc++.

sigil builds fine against the older boost 1.59.0, but if boost is then updated to 1.65.1, when sigil is run it fails to find the appropriate features in boost and faults out.

This version of sigil is quite out of date now. Most likely the fix here is to update sigil, unless someone sees a nice way to fix this.

build failure on 10.6.8 / libc++

[ryandesign (Ryan Carsten Schmidt)]

I'll look into updating it, in #48160.

This <​https://svn.boost.org/trac10/ticket/11902> might fix the current version.

I used the above link to make a fix for this version. Somewhere along the way they dropped qt4, so this version might be the last one that builds on 10.6 and less.

The newest versions use qtwebkit - there is something about that that is complicated - I think it was dropped by QT and picked up by a third party, although I think Rene's been working on it. Not sure where that is in the pipeline.
