Created attachment 209491 [details] build failure log If www/qt5-webengine 5.12.2 is installed, building 5.13.2 fails with multiple errors. I suspect the fix is to get the build to look in ${WRKSRC} before ${LOCALBASE} for include files (-I options). A workaround is to delete the old version of qt5-webengine that is currently installed in ${LOCALBASE}. But this should be fixed to not require users to do that. A build log showing the failure is attached.
This is a known error and documented in UPDATING. The solution is to use a proper port-buildsystem (read poudriere) with isolated builds or deinstall the port prior to building it. I close this as "work-as-intended" -- even though that is not satisfactory, obviously :) mfg Tobias
(In reply to Tobias C. Berner from comment #1) Thanks. Sorry for not checking UPDATING.
No worries :)
