Already discussed on IRC, but for the record: Actually Qt QML has a runtime requirement for SSE2, so I am not sure the non-SSE2 build makes sense: https://sources.debian.org/src/qtdeclarative-opensource-src/5.12.5-5/src/qml/qml/v8/qv8engine.cpp/#L143 I think we should just switch the default build to SSE2 by passing CONFIG+=sse2 to qmake when DEB_HOST_ARCH_CPU = i386. -- Dmitry Shachnev
