[gtkada] Problem Linking a GtkAda Tutorial Program in a New Installation

[Minder, Lawrence - ES/IEWS]

Thank-You Dmitry for your response.

I looked at the gtkada.gpr file you mentioned and found it to be a project file for a UNIX system, and a project library file at that.

After many changes and tests, I morphed the file into a Windows GNAT compiler project main file for the GtkAda's tutorial hello.adb program, naming it hello.gpr.  I am not sure if this was the best approach, as I am totally new to Ada, the GNAT compiler and the GPS GPL IDE, but I did find that it worked.

I saved this GPR file to a text file and slightly reformatted it for this Email.  It is listed below.  Thanx again for putting me on the right path ... Larry Minder



Contents of File:  hello.gpr  (From the GtkAda tutorial Sub-Folder
================               helloworld)


project Hello is

   for Main use ("hello.adb");
   for Source_Dirs use ("C:\---MY_TEST_FOLDER_NAME---\GTKADA\Testing\helloworld");
   for Object_Dir use "C:\---MY_TEST_FOLDER_NAME---\GTKADA\Testing\helloworld";

   package Builder is
      for Default_Switches ("ada") use ("-IC:\GtkAda\include\gtkada");
   end Builder;

   package Compiler is
      for Default_Switches ("ada") use ("-g");
   end Compiler;

   package Binder is
      for Default_Switches ("ada") use ("-g");
   end Binder;

   package Linker is
      for Default_Switches ("ada") use ("-Wl,-luuid", "-lgtkada", "-lgtk-win32-2.0.dll",
"-lgdk-win32-2.0.dll", "-latk-1.0.dll", "-lgdk_pixbuf-2.0.dll", "-ljpeg", "-lpng",
"-lpangocairo-1.0.dll", "-lcairo.dll", "-lpangowin32-1.0.dll", "-lpango-1.0.dll",
"-lgobject-2.0.dll", "-lgmodule-2.0.dll", "-lglib-2.0.dll", "-lintl", "-LC:\GtkAda\lib", "-LC:\GtkAda\lib\gtkada\static", "-LC:\GtkAda\include\gtkada");
   end Linker;

end Hello;

Hmm, he should have better advised you to use the GPS and the gpr project
files distributed with GtkAda.

Anyways, if you for some reason want to use bare gnatmake then under
Windows you indeed have to specify all libraries you need. There are a few
of them, the exact list is in the gtkada.gpr file.

The command might look like:

gnatmake -static -IC:/GtkAda/include/gtkada hello.adb -largs
-LC:/GtkAda/lib/gtkada -lgtkada -LC:/GtkAda/lib -lgtk-win32-2.0
-lgdk-win32-2.0 -lglib-2.0 -lgobject-2.0 -lgdk_pixbuf-2.0 -lpango-1.0
-mwindows

(I assumed static linking. Under Linux there is a script you can add to the
command line in order get all libraries: `gtkada-config --static`)
