osama's questions

I am trying to install gtk-server. First I typed the command ./configure and then make, but when I typed command make install it gave me this error:

osama@osama-HP-Compaq-6910p:~/Downloads/gtk-server-2.3.1-sr$ make install

i am trying to call a octave function from C code but the problem is that when why run this command in octave mkoctfile --mex addition_GUI.c error occurs addition_GUI.c:1:20: fatal error: gtk/gtk.h: No such file or directory compilation terminated.

I want copy and paste a file. The name of the file is mkoctfile.m.
The path of this file is:

/usr/share/octave/3.2.4/m/miscellaneous/mkoctfile.m

I want to paste it to the following path

/usr/bin/mkoctfile-3.2.4

I have made the directory by using following commands:

sudo su mkdir -p /usr/bin/mkoctfile-3.2.4

but I don't know how to copy and paste mkoctfile.m in this path.

Please tell me what command I have to use.

octave-3.2.4:1> mkoctfile --mex myhello.c
sh: 1: /usr/bin/mkoctfile-3.2.4: not found
warning: unable to find mkoctfile in expected location: `/usr/bin/mkoctfile-3.2.4'
warning: mkoctfile exited with failure status

I have searched for mkoctfile and i found it in this path

/usr/share/octave/3.2.4/m/miscellaneous/mkoctfile.m

Please tell me what I should do to create mex file

I am trying to use make command to build. I am following this. I am compiling a code using GTK+2 and C language

hp@ubuntu:~/amhello$ make

this is the main.c code

    return (0);
}

The tutorial I am following is the automake hello world. I am compiling a code using GTK+2 and C language

This is the line number 448 of Makefile ~/amhello % cat src/Makefile.amz

My code C is as below

#include<config.h>
#include<stdio.h>
#include<gtk/gtk.h>

void static call(GtkWidget *widget,gpointer data)
{
g_print("%s \n",(gchar*) data);
}

gtk_container_set_border_width(GTK_CONTAINER(window),10);

gtk_main();
return (0);
}

Contents of the src/Makefile.am are given below

bin_PROGRAMS = hello
hello_SOURCES = main.c

I figured out what was the error now another error is occuring when I use make command

I have already created the amhello-1.0.tar.gz using this tutorial click to open

now am trying to make cross compiling but error occurs. i am following this tutorial click to open

after entering make command error occurs

i want to create a .exe file which can run on windows. i have written a simple code to generate a window with a button in gtk. i have compiled this code and it is working properly using the command

    gcc code.c -o code `pkg-config --cflags --libs gtk+-2.0`

i know using mingw32 .exe files can be created and i have created a .exe file of simple hello world c code using this command

    i586-mingw32msvc-gcc hello.c -o hello.exe

when i try to compile a c code having '#include' it gives error

    i586-mingw32msvc-gcc code.c -o code.exe `pkg-config --cflags --libs gtk+-2.0`

please guide me step by step and in detail i am new to Ubuntu

I have written code in C language using GTK. This code gives a window with 2 buttons, but I do not know how to make the standalone GUI application from this code.

Please explain to me step by step and in detail.

#include<gtk/gtk.h>
void static call(GtkWidget *widget,gpointer data)
{
    g_print("%s \n",(gchar*) data);
}

int main(int agrc, char *agrv[])
{
    gtk_init(&agrc,&agrv);
    GtkWidget *window,*button,*vbox;
    window=gtk_window_new(GTK_WINDOW_TOPLEVEL);
    g_signal_connect(window,"delete-event",G_CALLBACK(gtk_main_quit),NULL);
    gtk_window_set_title(GTK_WINDOW(window),"two button");

    vbox=gtk_vbox_new(0,0);
    button=gtk_button_new_with_label("button 1");
    g_signal_connect(button,"clicked",G_CALLBACK(call),(gpointer) "BUTTON 1");
    gtk_box_pack_start(GTK_BOX(vbox),button,0,0,0);
    button=gtk_button_new_with_label("button 2");
    g_signal_connect(button,"clicked",G_CALLBACK(call),(gpointer) "BUTTON 2");
    gtk_box_pack_start(GTK_BOX(vbox),button,0,0,0);
    button=gtk_button_new_with_label("Close");
    g_signal_connect(button,"clicked",G_CALLBACK(call),(gpointer) "BUTTON 2");
    gtk_box_pack_start(GTK_BOX(vbox),button,0,0,0);
    gtk_container_set_border_width(GTK_CONTAINER(window),10);
    gtk_container_add(GTK_CONTAINER(window),vbox); 
    gtk_widget_show_all(window);
    gtk_main();
    return (0);
}
