Are you or anyone able/willing to reproduce the issue? Cause without reproducing it, there is no way for you guys to be sure that the package is actually causing any problems. I pasted the old email at the end below cause it has the steps to reproduce. Good day to you and thanks, Anwar N.B. Antonio’s advice is a good last resort. But I think a lot of developers would want to have their environment setup from source (<A HREF="https://www.gtk.org/docs/installations/linux/">https://www.gtk.org/docs/installations/linux/</A>). So if we fix it it’d help everyone. -----Original Message----- From: Tadeus Prastowo [<A HREF="mailto:tadeus.prastowo@unitn.it">mailto:tadeus.prastowo@unitn.it</A>] Sent: Thursday, April 9, 2020 6:49 AM To: Anwar Moukaddem <anwar.moukaddem@gmail.com> Cc: cairo@cairographics.org Subject: Re: [cairo] libcairo2-dev On Wed, Apr 8, 2020 at 11:35 PM Anwar Moukaddem <<A HREF="mailto:anwar.moukaddem@gmail.com">anwar.moukaddem@gmail.com</A>> wrote: > > Hi ! > > It's not uncommon to use self-compiled packages.

So, your e-mail is already off-topic for this mailing list: the problem is not Cairo but the way you configure your custom system. By following Antonio's advice, you will already get whatever you need to develop GTK3 software on your Ubuntu 18.04 system; there is no need to get the exact versions given in the link <A HREF="https://www.gtk.org/docs/installations/linux/">https://www.gtk.org/docs/installations/linux/</A>. If following Antonio's advice you find out that you miss something to develop your GTK3 software, you should post in the Ubuntu forum/mailing list that deals with GTK3, not here. Good luck! > Anwar -- Best regards, Tadeus Hi ! It's not uncommon to use self-compiled packages.

The installed packages are not dev packages. You can download the sources from the link and that's what I did. Ubuntu 18.04 comes with those dev packages already. Why don't you try to find all packages listed in <A HREF="http://archive.ubuntu.com/ubuntu/dists/bionic/main/binary-amd64/Packages.xz">http://archive.ubuntu.com/ubuntu/dists/bionic/main/binary-amd64/Packages.xz</A> that matches the regex pattern "^Packages: .+-dev" ?

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. Anwar N.B. I tried this both on an amd64 physical system and on a virtual machine, result is the same. -----Original Message----- From: Tadeus Prastowo [<A HREF="mailto:tadeus.prastowo@unitn.it">mailto:tadeus.prastowo@unitn.it</A>] Sent: Wednesday, April 8, 2020 4:00 PM To: Anwar Moukaddem <anwar.moukaddem@gmail.com> Cc: cairo@cairographics.org Subject: Re: [cairo] libcairo2-dev On Wed, Apr 8, 2020 at 7:21 PM Anwar Moukaddem <anwar.moukaddem@gmail.com> wrote: > > Hello Bryce & List, > > I compiled steps to reproduce: > > GTK3+ recommends the following packages : > > atk-2.26.1.tar.xz > > gdk-pixbuf-2.38.2.tar.xz > > glib-2.60.7.tar.xz > > gobject-introspection-1.60.2.tar.x > > gtk+-3.24.16.tar.xz > > gtk-doc-mainline.zip > > libcairo2-dev_1.14.6-1_amd64.deb > > meson-0.54.0.tar.gz > > pango-1.42.4.tar.xz > > We're only building/installing those, with their dependencies, on a fresh Ubuntu.

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? > Anwar -- Best regards, Tadeus </BODY> </HTML>
