running GTK

[c4t0]

Hi!

I've checkouted last commit a couple of days ago:
dfe4b5660037c4d178853ee00458a75e51a88563

compiled with this script:

#!/bin/bash

dst_dir="$(pwd)/build"

export CFLAGS="$CFLAGS -ffat-lto-objects -Wl,--allow-multiple-definition
-w"
autoreconf -iv
./configure \
    --prefix="${dst_dir}" \
    --enable-gtk=yes \
    --enable-preemption \
    --with-readline \
    --with-libltdl \
    --with-system-libffi \
    --with-system-libsigsegv \
    --with-tk \
    --with-tcl \
    --with-x \
    --without-emacs \
    --enable-static
echo '#define USE_INTERP_RESULT 1' >> config.h
make -j6
make install

Then tried to run gst-browser and it failed, so I tried to debug it, by
first making a minimal test:

$ echo "PackageLoader fileInPackage: 'GTK'." > test.st
$ build/bin/gst test.st

and that gives:

"Global garbage collection... done"
Loading package GLib

It seems to be quite broken :(

After tweaking around with build/share/smalltalk/GTK.star, namely
commenting some of the <filein>

<package>
  <name>GTK</name>
  <namespace>GTK</namespace>
  <prereq>Cairo</prereq>
  <prereq>GLib</prereq>
  <module>gst-gtk</module>

  <filein>GtkDecl.st</filein>
  <filein>GtkImpl.st</filein>
</package>

I can reduce the errors:

$ build/bin/gst test.st 
"Global garbage collection... done"
Loading package GLib
Loading package Cairo
Loading package GTK
./build/share/smalltalk/GTK.star#VFS.ZipFile/GtkImpl.st:1: key

Eval, Namespace or class definition
./build/share/smalltalk/GTK.star#VFS.ZipFile/GtkImpl.st:8: expected
expression

The first error can be "solved" by adding the class definition in
GtkDecl.st:

Object subclass: GtkTextBuffer [
    <category: 'Gtk'>
    <comment: nil>
]

and so on with the other errors that pop ups... obviously I'm shooting
in the dark here and something is missing, be it configuration,
compilation options, libraries or code I don't quite know. It seems that
all the libraries, headers and binaries are in place and the problems
are to be found in ST code.
Where are the cCalls of all those classes? For instance, where are all
the bindings for GtkTextBuffer?

I found out of this project a while ago and I find rather interesting
the idea to use Emacs for smalltalk programming, building apps with gtk
support, and using a graphical browser to aid development instead of
being forced to use it. Emacs could use Smalltalk-in-Smalltalk package
to provide auto-completion via company-mode, etc. It a shame that this
project is so abandoned.

So any help to get GTK bindings working or understanding the code base
and what needs to be done in case that more coding is needed, as well at
what setup do dev use for GST coding, would be appreciated.

Bye!
