py-qscintilla-qt5 @2.11.2_0: error: no matching constructor for initialization of '::QsciAPIs []'

[steflhermitte]

Dear,

I am doing a fresh installation of (the default) qgis3 on a newly re-installed MacPorts (Catalina 10.15), but the installation fails due to a py36-qscintilla-qt5 error (see part of error log below and complete error log attached). Therefore I cannot install the default qgis3 or any of its variants.

The problem also appears with other python variants of py-qscintilla-qt5 (e.g. py37-qscintilla-qt5, py36-qscintilla-qt5, py38-qscintilla-qt5).

The problem seems related to an earlier (but 17 month old) ticket (#58067), but I have no idea to resolve it. I have successfully installed earlier versions of qgis3 (and dependencies) over the past months without ever facing this problem.

Thanks in advance and best regards, Stef

#58067 does not appear to be related. In #58067 py-qscintilla-qt5 could be built but qgis3 could not, while here py-qscintilla-qt5 cannot be built.
