While discussing possible soloutions to bug 833770 Graham Inggs sugested
What about uploading version 1.1.1 from experimental to unstable?
Emilio Pozuelo Monfort pointed out.
Note that the experimental version fails to build on armel/armhf (at least).
I decided to take a look at this.
It appears that Eigen::Vector3d produces a Matrix<double, 3, 1> but
electronDensity expects a Matrix<qreal,3,1>
On most architectures qreal is defined as double, so this works but on
arm32 architectures qreal
is defined as float so it breaks
The first thing I tried was changing stuff from qreal to double to make
it match but that led down a massive rabbit hole.
So I then took a closer look at what Eigen::Vector3d was. Turns out it's
a typedef for Eigen::Matrix< double , 3 , 1>
So it seems the fix is simply to replace Eigen::Vector3d with
Eigen::Matrix< qreal , 3 , 1>. I've just set off a test build with that
change, will report results in the morning.
