Hi all,
Well, after building a few packages from EPEL for aarch64, and installing already built noarch packages from the x86_64 tree when the buildreqs were either circular or could not be satisfied (python34 didn't want to successfully rebuild, for instance, and quite a few of the GNURadio buildreqs for some reason need python3-devel to build.....), I finally got a complete package set to satisfy all of the buildreqs for current (3.7.9.2) GNURadio, using the GNURadio-supplied build-gnuradio script (not the RPM build; I'm working on that on the x86_64 box first, then will rebuild the SRPM once I have one for 3.7.9.2). And no, the EPEL version of GNUradio (3.7.5) is not recent enough for my purposes..... unfortunately.
I am more and more impressed with the speed of the ODroid C2, by the way.
I either built or installed the EPEL/x86_64 noarch for the following packages: ++++++++++++ bakefile.aarch64 bakefile-debuginfo.aarch64 cppzmq-devel.aarch64 czmq.aarch64 fontawesome-fonts.noarch fontawesome-fonts-web.noarch gtk2-engines.aarch64 gtk2-engines-devel.aarch64 lato-fonts.noarch libdb4.aarch64 libdb4-devel.aarch64 libdb4-doc.noarch libdb4-utils.aarch64 libsphinxclient.aarch64 libsphinxclient-devel.aarch64 openpgm.aarch64 openpgm-devel.aarch64 perl-AnyEvent.aarch64 perl-Curses.aarch64 perl-Event.aarch64 perl-ExtUtils-Depends.noarch perl-ExtUtils-PkgConfig.noarch perl-Glib.aarch64 perl-Glib-devel.aarch64 perl-IO-Pipely.noarch perl-POE.noarch perl-Test-ConsistentVersion.noarch perl-Test-Pod-Content.noarch perl-Test-SharedFork.noarch perl-Test-TCP.noarch perl-ZMQ-Constants.noarch perl-ZMQ-LibZMQ3.aarch64 php-pecl-sphinx.aarch64 python-bson.aarch64 python-chameleon.noarch python-colander.noarch python-cornice.noarch python-cornice-sphinx.noarch python-d2to1.noarch python-empy.noarch python-ipython-console.noarch python-ipython-sphinx.noarch python-jsonschema.noarch python-mistune.aarch64 python-oslo-sphinx.noarch python-paste-deploy.noarch python-path.noarch python-pathlib.noarch python-pbr.noarch python-pymongo.aarch64 python-pyramid.noarch python-repoze-lru.noarch python-simplegeneric.noarch python-simplejson.aarch64 python-sphinx_rtd_theme.noarch python-sphinxcontrib-adadomain.noarch python-sphinxcontrib-cheeseshop.noarch python-sphinxcontrib-httpdomain.noarch python-sphinxcontrib-issuetracker.noarch python-sphinxcontrib-napoleon.noarch python-translationstring.noarch python-txzmq.noarch python-venusian.noarch python-webob1.4.noarch python-zmq.aarch64 python-zmq-tests.aarch64 python-zope-component.noarch python-zope-configuration.noarch python-zope-deprecation.noarch python-zope-event.noarch python-zope-i18nmessageid.aarch64 python-zope-schema.noarch python2-mock.noarch qwt.aarch64 qwt-devel.aarch64 qwt-doc.noarch qwtpolar.aarch64 qwtpolar-devel.aarch64 qwtpolar-doc.noarch sphinx.aarch64 sphinx-java.aarch64 sphinx-php.aarch64 web-assets-devel.noarch web-assets-filesystem.noarch web-assets-httpd.noarch wxBase.aarch64 wxGTK.aarch64 wxGTK-devel.aarch64 wxGTK-gl.aarch64 wxGTK-media.aarch64 wxPython.aarch64 wxPython-debuginfo.aarch64 wxPython-devel.aarch64 wxPython-docs.aarch64 zeromq.aarch64 zeromq-devel.aarch64 zeromq3.aarch64 ++++++++++++
