#67573 assigned defect

qtwebengine ports no longer configure with MacPorts’ re2

Reported by: chrstphrchvz (Christopher Chavez) Owned by: MarcusCalhoun-Lopez (Marcus Calhoun-Lopez)
Priority: Normal Milestone:
Component: ports Version: 2.8.1
Keywords: Cc: mascguy (Christopher Nielsen), herbygillot (Herby Gillot)
Port: qt513-qtwebengine qt5-qtwebengine

Description (last modified by chrstphrchvz (Christopher Chavez))

The ports for qtwebengine 5.13 and 5.15 depend on MacPorts’ re2, but the configure test fails due to re2 now requiring Abseil which requires C++14, and so -std=gnu++11 (presumably a default flag from qmake) as used by the configure test is not allowed.

Port: qt6-qtwebengine removed

To correct myself, qt6-qtwebengine is not affected by this (presumably since it uses C++17)

They are certainly trying be super super sure that -DNOMINMAX gets defined ... :>

Replying to kencu:

They are certainly trying be super super sure that -DNOMINMAX gets defined ... :>

Presumably that is due to pkg-config --cflags re2 outputting seemingly identical flags from many of Abseil’s .pc files.

comment:5 Changed 18 months ago by chrstphrchvz (Christopher Chavez)

So far I have not figured out how to influence CXXFLAGS and override -std=gnu++11 for the configuration tests, except for the -z noexecstack check which does pick up qt5.cxxflags-append -std=gnu++14.

This seems more like a situation for compiler_wrapper, but given the degree to which qmake is likely also controlling compiler selection, that might involve something like the approach in the (Qt4) qmake portgroup.
