Re: [Pyfltk-user] My 1.4.2 build issue

[Robert A. <ro...@gm...>]

Hi,

We have not uploaded any wheel packages to Pypi for Fedora (or Linux).
Debian comes with python3-fltk package but Fedora does not. So you
will have to build the package from source. Instructions should be in
the INSTALL file of the source tarball from SF. However, another issue
is that you will need FLTK 1.4 as a dependency of pyfltk. But
unfortunately, Fedora still has no FLTK 1.4 package as you can see
from this thread https://groups.google.com/g/fltkgeneral/c/5wvb2cOngHY
So you will need to build FLTK from source as well.
