How to install latest GTK for creating C programs
You are missing a dependency required to run this program. Open the terminal and type:
sudo apt install libgtk-3-dev
Then compile the source code test.c with the following command:
gcc-5 `pkg-config --cflags gtk+-3.0` -o test test.c `pkg-config --libs gtk+-3.0`
I used gcc-5 instead of gcc-7 in Ubuntu 16.0-4 and test.c compiled successfully. In the upcoming release of Ubuntu 17.10 the gcc-7 package will be included in the default Ubuntu repositories and it will be possible to install gcc-7 quickly and easily with apt instead of gcc-5 which I have installed with apt in 16.04. In Ubuntu 18.04 GCC 7 is the default version of GCC and gcc-8-base can be installed from the default Ubuntu 18.04 repositories.
Then run the program with this command:
./test
and the results will be that an empty 200 × 200 pixel window with the title Window will appear which you can resize or close by clicking on the X. The window looks similar to the window in the Getting Started with GTK+ tutorial except that it has the default theme for your operating system.

I want to install latest version GTK to make small c programs. I've just finished "let us c" book which is very basic.Now I want to make GUI programs.while compiling the c program I got the following error by
gcc-7 test.c
test.c:1:10: fatal error: gtk/gtk.h: No such file or directory #include <gtk/gtk.h> ^~~~~~~~~~~
Thus I want to install latest version GTK to make simple GUI programs. I had gone to there website but there were so may files to download of which I don't know which to download. I want the latest version. so that my gtk would get upgraded when I typed
apt update && apt upgrade
I am using Xubuntu
Here is the source code from Getting Started with GTK+.
#include static void activate (GtkApplication* app, gpointer user_data) { GtkWidget *window; window = gtk_application_window_new (app); gtk_window_set_title (GTK_WINDOW (window), "Window"); gtk_window_set_default_size (GTK_WINDOW (window), 200, 200); gtk_widget_show_all (window); } int main (int argc, char **argv) { GtkApplication *app; int status; app = gtk_application_new ("org.gtk.example", G_APPLICATION_FLAGS_NONE); g_signal_connect (app, "activate", G_CALLBACK (activate), NULL); status = g_application_run (G_APPLICATION (app), argc, argv); g_object_unref (app); return status; }

terdon almost 7 yearsOK, so what did you try to install?
-
rahul almost 7 years@terdon I Don't what to download thus I didn't download anything.is there any simple command?
-
dobey almost 7 yearsIt depends on which version of GTK+ your code is written for, but as is the same with any libraries you use, you must install the development packages to compile software and link against those libraries. Ie the
libgtk3.0-dev
package. -
terdon almost 7 yearsBut, surely you tried searching for the relevant package, right? You wanted an
apt
command, so I assume you must have tried a few, or searched for package names. So what did you find? How did it not work? -
rahul almost 7 years@terdon I've search internet and I had found so many apt commands.Like
sudo apt install libgtk2.0-dev
and then something config and make commands of which i don't have any idea . -
steeldriver almost 7 yearsIn order for us to tell you which gtk+ version you should install, we need to know which version your C program was written for (v2 or v3)
