Re: Qt5 switching qreal from float to double on arm*



Hello,

Simple question: what is the reason for the change?

Also, I seem to remember Thiago discussing about this on qt-interest but I don't have time to search just now.

Hi! Starting from Qt 5.2.0 (most probably from rc1 and definitely not from
beta1 currently in experimental) Qt5 will switch qreal from float to double on
arm*.

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.

Of course we are still on time to discuss this, and this is the reason of this
mail. What do you think WRT the above changes?

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 because on Qt4 qreal will be
kept as float.

Any feedback will be kindly appreciated.

Kinds regards, Lisandro.
