Hello all,
Following an update on my Linux-Server (Ubuntu), where I have an
instance of qgis mapserver running, I stumbled upon a small gotcha - it
stopped working.
The reason was simple: The binary of qgis_mapserv.fcgi got updated, but
when I set up qgis mapserver, I followed the suggestion as described under
https://docs.qgis.org/2.18/en/docs/user_manual/working_with_ogc/server/getting_started.html#installation
under the heading "Server the project" to put a project into a separate
directory with the .qgs file and a *Copy* of qgis_mapserv.fcgi
After the update this *copy* of the binary could not find the right
shared library anymore (the update replaced libqgis_gui.so.2.18.14 with
libqgis_gui.so.2.18.15, to be specific).
To avoid this problem in the future with the next update, I replaced the
*copy* of the mapserver-binary with a soft link to the installed,
original qgis_mapserv.fcgi
So: The state after a clean installation under Ubuntu is:
/usr/lib/cgi-bin/qgis_mapserv.fcgi
Following the recommendation of the documentation, which is a good one!
You have:
/usr/lib/cgi-bin/qgis_mapserv.fcgi
and your project-dir(s) for example
/usr/lib/cgi-bin/myproject/
So, on the console you go into your project dir and instead to copy the
qgis_mapserv.fcgi you add a soft-link:
cd myproject
ln -s ../qgis_mapserv.fcgi .
I do not know if this is an "old hat", and it was only me who had this
problem, but nevertheless I would like to suggest a small change to the
documentation, to avoid this in future, at least for some people, like me...
All the best,
Albin
