Debian packages (binaries and sources) for 32-bit and 64-bit systems can be found in my debian-repo.
These packages are build against wxWidgets 3.0 from Debian repos and mght not be as stable than the versions build against wx2.8, but there are no wx2.8 packages available (at least for stable) from official repos.
Please test and give feedback.
Currently compiling, will soon be uploaded.Fedora
packages (binaries and sources) for 32-bit and 64-bit systems (fc20, fc21, fc22 and rawhide), RedHat/CentOS 5 and 6 packages (also 32-bit and 64-bit) and RedHat/CentOS 7 packages (only 64-bit at the moment) can be found in my rpm-repo
I recently switched to copr
to build and host my Fedora and CentOS packages.
Instructions how to use it can be found on my server
(easier) or on copr
(a little more handwork needed).
Packages for ppc64le
are also available on copr
for Fedora 21, 22 and Rawhide (not tested).
