QDir::mkpath() fails when creating paths that start '/cygdrive/'. This
problem is only shown with Qt5 (not Qt4), and only with paths that
start '/cygdrive/' (so running from my home directory '~' is fine).
This is not a permissions problem, as it works fine with Qt4.
Sample programme is below. Compile for Qt5 as per the comments. 'cd
/cygdrive/X' where X is a local drive where you have permissions to
create a directory. Run './create_directory new_dir' and it fails to
create the directory. Programme works fine when compiled with Qt4.
I have updated to libQt5Core5-5.4.2-2, and I'm still getting this
problem. Is anyone else able to reproduce this, or offer some insight as
to why it might be failing? For completeness, my example programme is
included below.
