Bugzilla Automation <bugzilla at FreeBSD.org> has asked freebsd-office mailing
list <office at FreeBSD.org> for maintainer-feedback:
Bug 239988: editors/libreoffice: update 6.2.5 -> 6.3.0 compiler failure:  no
viable constructor ...
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=239988



--- Description ---
Recent ports tree update (at r509423) results in an update of port LibreOffice
6.2.5 -> 6.3.0, which fails with the compiler error shown below:

[...]
[CXX] vcl/qt5/Qt5Object.cxx
/usr/ports/editors/libreoffice/work/libreoffice-6.3.0.4/vcl/qt5/Qt5Instance.cxx
:416:25:
error: no viable constructor or deduction guide for deduction of template
arguments of 'function'
	RunInMainThread(std::function([&, this]() { pPicker =
createPicker(context, eMode); }));
			^
/usr/include/c++/v1/functional:1427:48: note: candidate template ignored: could
not match 'function<_Fp>' against '(lambda at
/usr/ports/editors/libreoffice/work/libreoffice-6.3.0.4/vcl/qt5/Qt5Instance.cxx
:416:39)'
template<class _Fp> class _LIBCPP_TEMPLATE_VIS function; // undefined
[...]

Recompiling/updating ALL qt5-* ports or updating the ports tree and updating
installed ports (traditional make variant) prior to the update of port
editor/libreoffice doesn't result in a successful build.
