GTK+ and OpenWatcom

[moromete]

Hi !

I want to know if GTK+ can be used with OpenWatcom compiler.

thanks !

[moromete]

Hi !

I have installed GTK+, no problems to compile programs with
OpenWatcom.
Linking is not working, it seems the wlink can't use GTK+ libraries.

It would be good if your question included the platform you are working on
and OW version.

If it is on Linux, it is understandable, since OW does not support shared
libraries yet.
(see http://www.openwatcom.org/index.php/Linux_Port)
If you are on a different platform, more details on what goes wrong would
be useful.

You have right, sorry for that.
I'm using openwatcom 1.9 on windows.

I don't have more details now, i'm at office, but i will post
details soon.

I'm using openwatcon in windows.

If the GTK+ libraries are C++ that is probably not resolvable, as each tool
chain has their own expectations for what the RTL does to support certain
features. The libraries would have to be compiled by OW also. OTOH, if it
is C and assembly, it probably only needs calling conventions specified.
The OW documentation discusses this.

Are you using GTK as Win32 DLLs or as linkable libraries ?

If Win32 DLLs, are you creating new link libraries using the
wlib tool ?

If linkable libraries, what was used to create these ? Are
you sure that the linkable libraries are compatible with OW ?
Each linker manufacturer tends to have their own binary library
file structure that is not usable by other linker manufacturers.

This is just a guess, but you may have to specify stack calling
convention. I see from the line

\atk-1.0 -w4 -e25 -zq -od -d2 -6r -bt=nt -fo=.obj -mf -xs -xr

that you are using register calling to compile (that is the -6r that is
the default). The Microsoft calling convention is stack based and I
believe that OW decorates the reference names (leading, trailing, double
underscore) to keep these things sorted. With register calling, the
reference is not getting the correct decoration to be found in the
library. Finding the place to change convention is a bit of a
search--try compiler options.

i'm using DLL's
i try to create the import library for libgtk-win32-2.0-0.dll with the
command:

wlib mylib.lib -+libgtk-win32-2.0-0.dll

and i try to use the new import library mylib.lib, but same result

[Roald Ribe]

I agree, this most likely to be the solution. Open Watcom manuals,
the wiki and the Internet at large has a lot of information about DLL
calling conventions.

We would all be better off the .h files for DLL based libraries
decorated function prototypes with the correct calling convention.

Does this mean we can create the GTK+ library on Windows and use OW in
windows for Linux targets and create GTK+ compatible Linux applications?

Problem SOLVED !

i have downloaded the runtime and theme package package from here:
http://gtk-win.sourceforge.net/home/index.php/en/Downloads
runing wlib on needed dll's like this:
wlib -n -inn mygtk-win32-2.0-0.lib +libgtk-win32-2.0-0.dll
downloading dev packages from here:
http://www.gtk.org/download-windows.html
installing dev packages in c:\gtk2
must copy all my*.lib in c:\gtk2\lib
in openwatcom IDE Options->C++ Compiler Switches on "Include
directories [-i] add:

\gtk2\include \gtk2\include\gtk-2.0 \gtk2\lib\glib-2.0\include
\gtk2\include\glib-2.0\include \gtk2\include\glib-2.0 \gtk2\include
\cairo \gtk2\include\pango-1.0 \gtk2\lib\glib-2.0\include \gtk2\include
\glib-2.0\include \gtk2\lib\gtk-2.0\include \gtk2\include\atk-1.0

and on "Switches for making '*.cpp' in target" set -6s

and i's WORKING

hope to be usefull

No. GTK+ on Linux is based on shared libraries. Which OW does not support.
Currently OW can only be used on Linux if you can compile all the
functionality you need into the same executable, and if none of that
functionality depends on other shared libraries.
In practice this means command line utilities or curses based / curses
like text mode applications is possible, and little else.

There is a design for the necessary functionality extensions in the C
compiler and the linker on the wiki, but so far nobody with the right
knowledge or the right itch has turned up to implement it. I guess it is
just easier to switch to a different compiler than to add the
functionality to OW.

On Windows OW has full support for shared libraries (DLL's) so there
should be no big problems using GTK+ on that platform, even if the DLL's
has been made with a different compiler.

That's good to hear. If you feel inclined the details of how to do this
this might be worth adding to the Wiki for others to enjoy.

I understand that you might have other things to do. :)

You would have to create an account for yourself on the Wiki, then find
some suitable place for the information, and finally edit that page to
add what you know. However, I'm not sure where would be the best place
to add the information.
