qt.conf is there mainly for qmake, which needs to know both target paths and host paths. Now unfortunately, this also affects lupdate which expect LibraryExecutables to be a host path, while qt.conf tells qmake that it's really HostLibraryExecutables.
Changing Prefix to be a relative path would then break all qmake builds. -samuli ________________________________ From: Development <development-boun...@qt-project.org> on behalf of arslan.ahmad--- via Development <development@qt-project.org> Sent: 02 June 2023 11:58 To: Joerg Bornemann <joerg.bornem...@qt.io>; development@qt-project.org <development@qt-project.org> Subject: Re: [Development] unable to use lupdate(qt tools) in yocto sdk due to incorrect paths > Looks like you're somehow mixing a host Qt and a cross-compiled Qt? lupdate assumes that lupdate-pro is located in the same host Qt that lupdate belongs to.
