I am attempting to install gtk+-2.0, but when I try to do so I get the following error:
$ apt install gtk2.0

Does anyone know how I can install gtk+-2.0 on Trisquel 8 ?
As far as I understand, the package named libgtk2.0-0 in Trisquel's repository provides GTK+ 2. With the regular edition of Trisquel (using MATE), it is installed by default.
Thank you for your reply.
Yes it does seem I already have libgtk2.0-0 installed:
apt install libgtk2.0-0
Reading package lists... Done
Building dependency tree
Reading state information... Done
libgtk2.0-0 is already the newest version (2.24.30-1ubuntu1.16.04.2).
0 to upgrade, 0 to newly install, 0 to remove and 2 not to upgrade.
So that would mean gtk+2.0 is in fact installed - correct ?
The reason I asked the question is that I am actually trying to build gtkam which when I try to configure gives me the following error:
checking libgphoto2 cpp flags... "-I/local/usr/local/gphoto2/include"
checking for gp_port_info_get_name... no
checking for GTK... no
configure: error: Package requirements (gtk+-2.0) were not met:
No package 'gtk+-2.0' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables GTK_CFLAGS
and GTK_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
Possibly this means it is looking in the wrong place ?
Looking at the configure file it looks like it uses the following command to determine the existence of the package:
/usr/bin/pkg-config --exists --print-errors gtk+-2.0
I do not know where pkg-config looks by default, but is it possible this is not looking in the correct place ? and if so where the package would be found (so I can add it to PKG_CONFIG_PATH)?
Thank you for the reply.
Initially when I tried to install libgtk2.0-dev I git the following error:
$ apt install libgtk2.0-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done

Depends: gir1.2-gtk-2.0 (= 2.24.30-1ubuntu1) but 2.24.30-1ubuntu1.16.04.2 is to be installed
However doing:
apt install libgtk2.0-0=2.24.30-1ubuntu1
apt install gir1.2-gtk-2.0=2.24.30-1ubuntu1
apt install libgtk2.0-dev
Seems to have installed it successfully.
For completeness I also needed to install
apt install libexif-gtk-dev
to get gtkam to configure correctly. Now it doesn't build - guess I'll try to find a gphoto forum to query that one.
Thank you very much for our help.
