Hello, I want to install version 2.6.2 (the latest) on Linux Mint 19.1. As I've already checked, I have GTK 3.22 installed, but I still get this when I type ./configure:

checking for GTK3... no

and later this:

checking for GTK+ - version >= 2.12.0... Package gtk+-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtk+-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gtk+-2.0' found
no
*** Could not run GTK+ test program, checking why...
*** The test program failed to compile or link. See the file config.log for the
*** exact error that occurred. This usually means GTK+ is incorrectly installed.

I've been battling with this all day now, but I'm a newbie in terms of this stuff. Can someone tell me what am I missing?

GTK 3.22 and GTK 3 are, broadly speaking, two different things. Newer (as in, non-stable) Freeciv versions come with dedicated GTK3.22 client clode, but for older ones, you'll need a GTK3 installation that's not GTK3.22.

Thank you for the quick answer!

Yeah, my INSTALL file specifies a separate 3.22 client, that's why I thought I could use my 3.22.30.

you'll need a GTK3 installation that's not GTK3.22.

Is there a way to install GTK3 that doesn't involve compiling each dependency? Because I've had quite a few troubles with that yesterday (mainly with the gtk ./configure not detecting the dependencies installed).

On my (age-old) Ubuntu laptop, I was able to install the proper prebuilt libraries for all the GUI clients without needing to compile anything myself, so I'm afraid I can't help with that :/

The difference between gtk3-client and gtk3.22-client is that latter requires gtk+-3.22, and takes advantage of it. gtk3-client can be built with gtk+-3.22, but behaves the same with is as with any gtk+ version it supports (starting from 3.8).

You are probably missing gtk+-3 development files (separate '-dev' package that you should install in addition to the main library package you use when running the programs that use gtk+-3). In any case the 'config.log' file should contain more details about the issue. Please attach it here if you still can't figure out what's wrong.

I've tried to install development files it still tells me I have the latest already installed.

Yeah, I'll attach the file to this post. I'm kind of new to forums, so I hope I do it right.

I don't know Mint, but Wikipedia tells me that Linux Mint 19.1 is based on Ubuntu 18.04LTS, for which the relevant package you need to install (that is, the package containing the files "gtk+-3.0.pc" and "gtk.h") is called libgtk-3-dev (with something like "sudo apt install libgtk-3-dev", or whatever other method you normally use to install packages from the Mint repositories).

(This is as opposed to the package "libgtk-3-0", which you probably already have installed; that contains the libraries you will need to run Freeciv, but is not enough for you to build Freeciv from source code.)

If that's right, then Mint's Gtk3 version is 3.22.30, which is sufficient to let you build either the Gtk3.0 or Gtk3.22 Freeciv client (or both).

I suspect this won't be the last dependency package you'll need installed. In general, it's worth trying the wiki instructions for Debian-style distributions (but I don't know if that "apt-get build-dep" command will do anything useful on Mint specifically).

Corrections:

• The Gtk3.22 client is available in stable (2.6.x) Freeciv releases;
• The Gtk3.0 client (e.g. in the older Freeciv 2.5.x) should compile fine against Gtk3.22 or later, so if you specifically want to use it for some reason, there's no need to go out of your way to install an old version of the Gtk3 library;
• As of 2.6.2, I'm hoping that the Freeciv Gtk3.22 client works at least as well as the Gtk3.0 client on modern Linux (if not better), and that there's no reason to specifically want the Gtk3.0 client (although it is still the default build target).

Ok, so, long story short: I had a much bigger issue at hand that got me stuck in emergency mode. After a whole day of messing around with different possible solutions I had to reinstall Linux MInt.

After that, and installing a few development libraries (libcurl, gtk3 and a couple more that the ./configure asked for) I was suddenly able to install Freeciv 2.6.2 without any issue.
