Where is Ruby 1.9 'TK' library?

I got an interesting result. I was able to install tk_from_gem and it
installed and worked. However, if I run my Tk application using Ruby
1.9 it loads noticably slow (the Gui builds frame-by-frame as I watch
it). If I run the exact same application using Ruby 1.8, it loads
instantaneously.

Interesting. I get the same thing with tk_as_gem (and approximately the
same thing with 1.9.1 with tk "built inline" (non gem)) [1]

Wonder why it's slower.

What happens if you try and run ruby extconf.rb?

I'm away from my system this week. When I return I'll try running ruby
extconf.rb and let you know the outcome.

Thanks --Alex

-r

after running 'make' the results are:

gcc -shared -s -o tcltklib.so stubs.o tcltklib.o -L. -LC:/Ruby19/lib
-LC:/Tcl/lib -L. -Wl,--enable-auto-image-base,--enable-auto-import
-lmsvcrt-ruby191 -ltk84 -ltcl84 -lshell32 -lws2_32

Then I do 'make install' and get the contents of the attached .txt file.

After all is said and done, then when I try to run a ruby tk app I get
the following error:

C:/Ruby19/lib/ruby/site_ruby/1.9.1/tk.rb:7 in `require': no such file to
load - tkutil (Load Error)
     from C:/Ruby19/lib/ruby/site_ruby/1.9.1/tk.rb:7:in `<top

that it odd it should be creating several .so files

e:\>gem which tkutil
E:/installs/ruby191p376/lib/ruby/gems/1.9.1/gems/tk_as_gem-0.1.0/lib/tkutil.so

e:\>gem which tcltklib
E:/installs/ruby191p376/lib/ruby/gems/1.9.1/gems/tk_as_gem-0.1.0/lib/tcltklib.so

What does yours say for those commands after installing the gem? My
guess is that they exist but somehow aren't finding the dll's right or
something.

If you have the file tkutil.so, you can train "dependency walker" on it
[1], and it might inform you of missing dependencies or what not...
Let me know how it goes.

gem which tkutil results in:
ERROR: Can't find ruby library file or shared library tkutil

gem which tcltklib results in:
C:/Ruby19/lib/ruby/site_ruby/1.9.1/i386-msvcrt/tcltklib.so

If I search my entire C: drive for tkutil.so it finds a copy in my old
Ruby 1.8 installation, but not in the Ruby 1.9 installation. I don't
suppose I could just copy the file from the 1.8 install to the 1.9
install? If so, where should I put it?

That's the built-in one, I think, not the gem one...and this is after a
successful gem install? "gem search tk_as_gem" lists something? what
does "gem which tk" yield?

You might get some traction in building the gem on you 32 bit box and
then copying over that entire ruby version to your 64 bit box, too.

That worked! I copied the entire tk_as_gem-0.1.0 directory from my 32
bit install to the 64 bit machine, and it worked first time! Thanks for
the tip.

I have two additional questions:

1) Will the tk_as_gem work with a later version of Tcl/Tk, or do I need
to stick with the 8.4 version I am using now?

2) Any ideas as to why the Tk apps with Ruby 1.9 load so slow compared
to the way it was on Ruby 1.8?

Again, thanks for all your help. I'm happy that I can at least run my
apps now.

I think it will work with 8.5

2) Any ideas as to why the Tk apps with Ruby 1.9 load so slow compared

Nope. If you can reproduce it in Linux, you could ping core and ask
them why they think it's slow (or anybody else out there?).

I've had a trouble on extremely slow loading Ruby1.9/Tk on my linux box.
Then, the linux box worked fine. It had no other trouble.
Although I couldn't find the reason of why, it was gone after rebooting
the linux box.
