What do you think WRT the above changes? This will basically break the ABI of basically all the Qt5 libraries on those architectures. Unless upstream already managed the SONAME bump already, it would imply that Debian has to maintain it on its own... are you sure these changes are worth the pain they cause? > On the other hand, if the above change is kept, symbols for Qt5 on > armhf managed with pkg-kde-tools' symbolshelper will need an explicit > double for armhf instead of using qreal's subst.

This is another issue, i.e. pkgkde-symbolshelper not being able to distinguish version of qt for substitutions. > We have the option to keep some archs in float by passing a > compilation parameter. I've done so for armel and sh4, so only armhf > will switch to double. My option goes on keeping the status quo of qreal as it was, on architectures that managed to build qtbase-opensource-src already. -- Pino Toscano
