LyX @2.2.1: Undefined symbols: decltype

[manfredo89 (Manfredo di Porcia e Brugnera)]

--->  Building LyX
Error: org.macports.build for port LyX returned: command execution failed
Please see the log file for port LyX for details:
    /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_aqua_LyX/LyX/main.log
Error: Unable to upgrade port: 1

tried ​this but doesn't work. Also I have both Lyx and Lyx1 ports installed, is this a problem?

[ryandesign (Ryan Carsten Schmidt)]

Please attach the main.log file so we can see why the build failed.

Having LyX and LyX1 installed simultaneously should not be a problem.

In 207137ef9a4923e921ef8612e09cb4a2c6cdbd1b/macports-ports:

LyX: add qt5 variant

There should be no change to current build as qt4 is the default still.

Correct configure args; add Debian patch to fix spelling errors.

Add cxx11 PG
see #53877
see #52236
