Details

Description: vtk has a runtime dependency on double-conversion, but it is not listed in the PKGBUILD.

Running "ldd /usr/lib/libvtkIOCore.so.1" gives the following output (assuming double-conversion is not installed):

Additional info:

~$ pacman -Q vtk vtk 8.2.0-1

The issue seems to be comparable to https://bugs.archlinux.org/task/61601 . I'm aware that installing double-conversion will fix this issue.
