GTK interface programming (I): Environment Construction

One 、 Environment building

1. install GNU Compile link tool

sudo apt-get install build-essential

2. install gtk3

sudo apt-get install libgtk-3-dev

3. install pkg-config For automatic discovery gtk The location of the header file

sudo apt-get install pkg-config

After installation , You can use the following command to verify that the installation was successful , And look at GTK+3.0 The path of all the included header files and libraries ：

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

The verification results ：

4.GUI verification
Use the official example to test whether it can run
main.c The sample code is as follows ：

#include <gtk/gtk.h>
int main( int argc, char *argv[])
{
    
    GtkWidget *window;
    gtk_init(&argc, &argv);
    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    gtk_widget_show(window);
    gtk_main();
    return 0;
}

The compilation instructions are as follows ：

sudo gcc main.c -o main `pkg-config --cflags --libs gtk+-3.0`

function ：

./main

The verification results ：
