Troubleshooting the build process in
(x/l/k) ubuntu 18.10
Unfortunately as of today (Jan 29, 2019) in current Ubuntu cosmic
cuttlefish the wxWidgets binary that ships with the
distribution appears to be subtly broken.
As a result, on execution of academic signature(and some other
software), strange error messages are emitted and during some
operations the execution is progressively slowed down to the
First repair some broken dependencies in cosmic.
In a terminal type:
"sudo apt-get install --reinstall
"sudo apt-get install libcanberra-gtk-module"
The obvious solution for the broken wxWidgets is to download
the wxWidgets source code, compile it and replace the
-> 1. Download the wxWidgets source code e.g. wxWidgets 3.0.4
-> 2. Unzip it into any directory
-> 3. Enter the directory of wxWidgets in a terminal and create
a directory e.g. with name "built_gtk"
-> 4. Enter this directory in the terminal and type:
"../configure" or optionally
--disable-debug --enable-unicode --disable-shared --with-gtk" instead
-> 5. type "make
(this will take a while)
-> 6. type "sudo
and then "sudo
Now you should have fixed cosmic cuttlefish and building and
running academic signature (and some other wxWidgets dependent
software) will work like a charm.
Hopefully this will be fixed soon.
Unfortunately, errors seem to pile up: The faulty g++ optimization
-O2/-O3 as well as the inconvenience in the zesty build process
are still unfixed. So the errors obviously
have come to stay with us.....
