Sorry, I m greenhorn

initializer_list is a c++11 feature <​http://en.cppreference.com/w/cpp/utility/initializer_list>.

I would recommend that you follow the instructions in LibcxxOnOlderSystems, and upgrade your 10.7.5 machine to that configuration. Part of that configuration is to make clang-3.8 your default compiler, which will handle all further c++11 ports with no troubles or further input from you.

More and more ports need c++11, and if you do this, you will cover them all with no further adjustments on your end. However, it does mean you'll build all ports from source, which takes some time, but otherwise works very well. I have my 10.6.8 machine set up like this, and lyx just installed on that system without any hassle.

$ port -v installed lyx
The following ports are currently installed:
  LyX @2.2.2_0+python27 (active) platform='darwin 10' archs='x86_64' date='2017-03-28T18:10:09-0700'

Your other option is to post up build failures like this when you come across them, and people will update the portfiles as needed to include c++11 coverage. This takes time, and won't solve your immediate issues.

By the way, thanks for the pointer to lyx -- looks like a great piece of software!

admirable answer! Thanks for competent advice, I will follow that...

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

Reopen this if this is still an issue.
