Would it be possible to build libQtQml for i686/SSE2, install it into lib/sse2 and call it a day? I don't think it's worth shipping a pure i386 version of that library that's not going to perform on the hardware in question - more than 10 years old and no chance for GPU acceleration the way Qt needs it.

While on the topic, and looking at qtdeclarative's JIT on i686, https://bugreports.qt-project.org/browse/QTBUG-35430 would a similar workaround suffice for libQt5Qml? build a normal sse2/jit enabled version and stuff into LIBDIR/sse2 dir, and a non-sse2/jit into LIBDIR? -- Rex _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
