Compiling GTK + code

Question

How to compile GTK +?! I read the manuals and there are connected "options" but something is missing.

pkg-config --cflags --libs gtk+-3.0

Error

Actually, you should first read the errors generated by the compiler.
And at least to start correct syntax errors like this gtk_window_set_title (GTK_WINDOW), "Hello");
But you see that here gtk_window_set_title (GTK_WINDOW), "Hello");
As I understand it, you should set a title for the window object.
This is a completely illiterate source of information on GTK.
For example, one of the headlines looks like this: "Awareness, display and showing."
It is necessary to read the original sources, and not illiterate translations with a lot of typos.
Is the original source code different from what you gave here?
Those errors that are present at the link, say that the corresponding library is not connected to the project.
Well, the answer is also given there, how to write the command line.

http://www.linuxfromscratch.org/blfs/view/svn/x/gtk3.html check the dependencies and the version of the compiler.

What does compiler version have to do with syntax errors? - Vlad from Moscow
Pesnite how to do it Ps packages put through synaptic -> "libgtk-3-dev" - hays

Well, I think this way: "if the compiler gives errors, it means something is not installed, but if errors continue to go, then it is better to update the compiler, then the recommended version and not to go into the code and edit a bunch of lines." - Eugene P.
Look at the item: at-spi2-atk-2.16.0, gdk-pixbuf-2.31.6, and Pango-1.36.8. dpkg --list | grep <pkg> - Eugene P.

@Eugene P. How can a given sentence be gtk_window_set_title (GTK_WINDOW), "Hello"); one thousand and one time Explain please? - Vlad from Moscow
