hugin-app @2019.2.0_4 fails to build due to undefined symbols

[michaellass (Michael Lass)]

Building hugin-app fails for me with the following error:

:info:build Undefined symbols for architecture x86_64:

I'm on macOS 11.4 and boost is installed in version 1.71.0_4.

I just noticed that boost is installed in multiple versions:

  boost @1.71.0_4+no_single+no_static+python39 (active)
  boost176 @1.76.0_0+no_single+no_static+python39 (active)

Looks like 1.76 is the relevant one here.

Turns out this is some fallout of ​https://github.com/macports/macports-ports/commit/b25b206. It seems that hugin-app needs the older 1.71 version of Boost. I created a PR with a simple fix: ​https://github.com/macports/macports-ports/pull/11369

Might be that newer versions of hugin-app would build against newer versions of boost as well - I haven't tried updating the port.

hugin-app: build against boost 1.71

Building against boost 1.76, which is currently the default used by the boost
portgroup, fails with the following error:

Boost 1.71 matches the version that was used before b25b206.
