Forum: Ruby-Gnome 2 Problems Building on Windows

I am having a huge amount of problems building this on windows.
I admit that I am not following the directions on the website
because I would like to have something newer than 2.10.
I got the 2.22 bundle from gtk.org.  Maybe it's not supported?

Anyway, my first problem was that I needed to set the
PKG_CONFIG_PATH environment variable so that ruby-gnome2
could find my GTK installation.  It took me a long time to
figure that out, so it would be nice to have a note in the
documentation.

But then I ran into the problem that the mkmf-gnome2.rb
script doesn't set the CFLAGS from pkg-config.  I'm not
sure why because Kou's pkg-config script makes it quite
easy.

But then finally, some GTK variables can't be found.
It seems like 2.22 isn't supported yet. But I can't find
anything on the website saying what version *is* supported.
I don't believe it is 2.10 because that is more than 2
years old.

I would really, really like to build this so I can finally
release my application on windows.  Any help is
appreciated.

GTK+ 2.22 is supported.

Could you contribute your build instructions?
We want to update the following documents:
  http://ruby-gnome2.sourceforge.jp/hiki.cgi?compile_mingw
  http://ruby-gnome2.sourceforge.jp/hiki.cgi?compile_vc

Did you and pkg-config.rb find GTK+ *.pc?

We can install Ruby/GTK2 binary with GTK+ 2.22 binaries by
gem:

  > gem install gtk2

The gem was built with MinGW on my Debian GNU/Linux. (It's
cross compile.)

But GTK+ version isn't saied as you saied.
We should update the following document...
  http://ruby-gnome2.sourceforge.jp/hiki.cgi?Install...

That's good to know.  Probably there was something else wrong.

OK.  I will try again tomorrow.  I am using mingw right now.
If I can get it to work I will write some instructions.

Yes.  Once I set the PKG_CONFIG_PATH there was no
problem.  But the mkmf-gnome2.rb script doesn't seem
to use the config information.  I added some code like:

   gtk_config = PackageConfig.new("gtk+-2.0")
   CFLAGS += " " + gtk_config.cflags

It is possible I misunderstood something and it is handled
somewhere else.  But I couldn't get it to work without doing
this.

Ahh.  That's VERY good :-)  I didn't realize it.  I will use that.
But I will try to get everything built and then update the 
documentation.
My first language is English, so it's will be easy for me once I 
understand
what to do.

OK. I understand.
The current mkmf-gnome2.rb requires GTK+ and required
binaries are installed under
RUBY_GTK2_TOP_DIRECTORY/vendor/local/ direcotry.

  .
  |-- ext
  |   `-- gtk2
  |    ...
  .
  `-- vendor
      `-- local
          |-- bin
          |-- lib
          ...

See also directories in Ruby/GTK2 gem.

Thanks! It will be very useful.
