c++ - how to compile gtk+ application for native windows (and not for X windows)?

Question

I have managed to compile a gtk+ application with cygwin, but unfortunately with this approach, the application needs x windows running to be able to startup.

How can I compile my gtk+ application to run natively on windows.

I have seen various posts online about using the -mno-cygwin flag to gcc, but that seems to have been deprecated?

I have also seen these posts on stackoverflow, but its not clear if they are trying to compile for X, or natively for Windows:

• Installing gtk and compiling using gcc under windows?
• Compiling GTK+ applications on windows?

The application needs to be compiled using MinGW and not Cygwin.

The full list of steps I followed:

1) Download MinGW

2) Install MinGW to a folder without spaces, e.g. to c:MinGW.

3) Download gtk+. Even though my machine is 64bit, I went for the 32 bit download of gtk+ because compatibility warnings on the 64bit download page. The GTK+ Win32 downloads are here. I went for the all-in-one version.

4) Extract gtk+ to a folder without spaces, e.g. c:gtk

5) If you don't already have an application, you can use the gtk+ hello world source code. Save this to a folder, e.g. c:myapp

6) Open a windows command prompt and cd to the folder in step 5. E.g.

cd c:myapp

7) In the command window, add your MinGW folder to the windows PATH, e.g.

c:myapp> set PATH=c:gtkin;%PATH%

8) In the command window, add your gtk+ folder to the windows PATH, e.g.

c:myapp> set PATH=c:gtkin;%PATH%

9) Create a script to compile your application, e.g.

C:myapp> C:MinGWmsys1.0inash.exe -c "echo gcc -Wall -g helloworld.c -o helloworld `pkg-config --cflags gtk+-2.0` `pkg-config --libs gtk+-2.0` > compile.bat"

Note that I had to give the full path to bash.exe. For some reason adding c:MinGWmsys1.0in to the PATH and just using bash.exe didn't work for me.

10) compile your application with compile.bat, e.g.

c:myapp> compile.bat

12) execute your application, e.g.

c:myapp> helloworld.exe

---

EDIT:

For step 9, we are just creating a gcc command to compile gtk+ with the correct include and library option settings.

This is the contents of compile.bat that got generated for me:

gcc -Wall -g helloworld.c -o helloworld -mms-bitfields -Ic:/DEV/gtk224/include/gtk-2.0 -Ic:/DEV/gtk224/lib/gtk-2.0/include -Ic:/DEV/gtk224/include/atk-1.0 -Ic:/DEV/gtk224/include/cairo -Ic:/DEV/gtk224/include/gdk-pixbuf-2.0 -Ic:/DEV/gtk224/include/pango-1.0 -Ic:/DEV/gtk224/include/glib-2.0 -Ic:/DEV/gtk224/lib/glib-2.0/include -Ic:/DEV/gtk224/include -Ic:/DEV/gtk224/include/freetype2 -Ic:/DEV/gtk224/include/libpng14 -Lc:/DEV/gtk224/lib -lgtk-win32-2.0 -lgdk-win32-2.0 -latk-1.0 -lgio-2.0 -lpangowin32-1.0 -lgdi32 -lpangocairo-1.0 -lgdk_pixbuf-2.0 -lpango-1.0 -lcairo -lgobject-2.0 -lgmodule-2.0 -lgthread-2.0 -lglib-2.0 -lintl

Of which, the include options created by pkg-config --cflags gtk+-2.0:

-mms-bitfields -Ic:/DEV/gtk224/include/gtk-2.0 -Ic:/DEV/gtk224/lib/gtk-2.0/include 
   -Ic:/DEV/gtk224/include/atk-1.0 -Ic:/DEV/gtk224/include/cairo 
   -Ic:/DEV/gtk224/include/gdk-pixbuf-2.0 -Ic:/DEV/gtk224/include/pango-1.0 
   -Ic:/DEV/gtk224/include/glib-2.0 -Ic:/DEV/gtk224/lib/glib-2.0/include 
   -Ic:/DEV/gtk224/include -Ic:/DEV/gtk224/include/freetype2 
   -Ic:/DEV/gtk224/include/libpng14

(note I have put in line breaks above to improve readability on stackoverflow)

Notice that pkg-config --cflags gtk+-2.0 has put the full path of my gtk+ include files (c:/DEV/gtk224/include/).

And the library options generated by pkg-config --libs gtk+-2.0:

-Lc:/DEV/gtk224/lib -lgtk-win32-2.0 -lgdk-win32-2.0 -latk-1.0 -lgio-2.0 
   -lpangowin32-1.0 -lgdi32 -lpangocairo-1.0 -lgdk_pixbuf-2.0 -lpango-1.0 
   -lcairo -lgobject-2.0 -lgmodule-2.0 -lgthread-2.0 -lglib-2.0 -lintl

(note I have put in line breaks above to improve readability on stackoverflow)

Notice that pkg-config --libs gtk+-2.0 has put the full path of my gtk library folder (c:/DEV/gtk224/lib).
