[cairo] libcairo2-dev

Wed Apr 8 20:57:00 UTC 2020

Hello Tadeus, 

You get the recommendation straight from the source : https://www.gtk.org/docs/installations/linux/ 
I am installing a development environment.  The installed packages are not dev packages.   You can download the sources from the link and that's what I did.  
The list I provided is based on that.
This is why the dependencies were important to install and one of the dependencies is libcairo2-dev.

How did you get the recommendation?

FYI, Ubuntu 18.04 64-bit already comes with GTK3, specifically version
3.22.30.  And, the Ubuntu package of GTK3 only has the following
recommendation and suggestion: libgtk-3-bin, librsvg2-common, and gvfs
(you can see it yourself at
http://archive.ubuntu.com/ubuntu/dists/bionic/main/binary-amd64/Packages.xz).

So, basically you are re-installing GTK3 when Ubuntu 18.04 already
ships with it.  Why?

Ubuntu 18.04 has those packages already as you can see at
http://archive.ubuntu.com/ubuntu/dists/bionic/main/binary-amd64/Packages.xz:

Package: gobject-introspection
Architecture: amd64
Version: 1.56.1-1

Package: libpango-1.0-0
Architecture: amd64
Version: 1.40.14-1

Package: libcairo2
Architecture: amd64
Version: 1.15.10-2

So, I don't see that someone else would want to follow your steps.

Hello Tadeus,

My requirement is simple.  GTK3+ recommends packages that I've listed below.   These in turn have dependencies.

In order to satisfy the dependencies, all the steps below are required in that order.  When I say "required" I am basing myself on : Error messages received during installation.  
After each such error messages I am repeating the whole installation (no pollution possible).
This is why, installation steps below are all required to compile and build GTK3+ dependencies.

So as for Tadeus comment about "own steps", these are really steps imposed by the single requirement of installing GTK3+ development environment on a Ubuntu machine.   That includes gobject/pango/cairo.

N.B. I tried this both on an amd64 physical system and on a virtual machine, result is the same.

This is your own step.

These two are also yours.

Yours too.

These too.

Since you perform your own custom steps, then one of those may have
screwed something up.  What goes wrong, unfortunately, you have to
find out.

BTW, why do you need to perform such custom steps?
