Missing software on the macOS side
There are some pieces of software that were not correctly restored from the backup. Typically, things that installed stuff outside of the most standard areas, like /Applications. That notably includes the Red Hat certificates, so I have to go through multiple warnings every time I want to access an https:// web page, and then some stuff like Ajax does not work too well. Fortunately, the setup is quite easy (keyword "Red Hat Mac Setup").
Building Spice for macOS
Reinstalling the missing pieces to build Spice. Will need to add a README.macos, or better yet, a build script, to explain how to do it. It's not entirely trivial yet.
Recap of the things I had to install just to pass configure:
brew install pkg-config pixman gtk+3 gstreamer gstreamermm libjpeg-turbo
Among the changes:
- Now, openssl is at 1.0.2l (up from 1.0.2j). Since
openssl is put in the Cellar (i.e. it conflicts with built-in
macOS features), I still have to add the following before building:
export PATH=$PATH:/usr/local/Cellar/gettext/0.19.8.1/bin export CFLAGS="-ObjC -g" export CXXFLAGS=" -g" export CPPFLAGS="-I/usr/local/opt/jpeg-turbo/include -I/usr/local/include -I/usr/local/Cellar/openssl/1.0.2l/include" export LDFLAGS="-g -L/usr/local/opt/jpeg-turbo/lib -L/usr/local/lib -L/usr/local/Cellar/openssl/1.0.2l/lib"
One thing that I noticed and I did not know about is that CPPFLAGS is apparently only active for ./configure, i.e. you cannot just set CPPFLAGS after configure.
AFter that, I have a failure when running it against my Linux VMs:
% spicy -h 192.168.77.42 -p 5901** Message: main channel: opened Wrong JPEG library version: library is 80, caller expects 90
Building spice for Linux
Rebuilding work environment from scratch in the Linux partition, based on Fedora 26.
There is a bogus warning from configure:
configure: WARNING: The avdec_h264 GStreamer element(s) are missing. You should be able to find them in the gstreamer-libav 1.0 package.
The message talks about gstreamer-libav, but the actual package for gstreamer 1.0 is called gstreamer1-libav.
Then, there is an unfriendly error message at build time:
ddd@ptitfed spice-common> makemake all-recursive make[1]: Entering directory '/home/ddd/Work/spice/spice-gtk/spice-common' Making all in python_modules make[2]: Entering directory '/home/ddd/Work/spice/spice-gtk/spice-common/python_modules' make[2]: Leaving directory '/home/ddd/Work/spice/spice-gtk/spice-common/python_modules' Making all in common make[2]: Entering directory '/home/ddd/Work/spice/spice-gtk/spice-common/common' GEN generated_client_demarshallers.c make[2]: *** [Makefile:809: generated_client_demarshallers.c] Error 1 make[2]: Leaving directory '/home/ddd/Work/spice/spice-gtk/spice-common/common' make[1]: *** [Makefile:455: all-recursive] Error 1 make[1]: Leaving directory '/home/ddd/Work/spice/spice-gtk/spice-common' make: *** [Makefile:387: all] Error 2

Running manually to avoid the redirection to /dev/null:

There is a package for that, so dnf install python2-pyparsing does the trick (so would pip install pyparsing I guess. The benefit of using the module is that it means we can add the dependency so that dnf builddep spice-gtk works correctly.
3D acceleration for guests
The 3D acceleration for guests no longer works on Fedora 26 host. The qemu process crashes with:

Laptop setup
Received a new Lenovo laptop. Began the setup late in the day. Now, Cortana is talking to you and listening to your responses during setup. Which, at first sight, looks like a great idea for beginners. Until someone called me and, while answering the phone (in French) Cortana politely asked me "It looks like you want a Finnish keyboard" and then somehow interpreted my next answer as "Yes".
Fortunately, the mouse still works and you can go back
