Doesn't like tk gem

[catmando]

Running on windows 7, under the ruby one click installer. ruby 1.8.7 (2011-06-30 patchlevel 352) [i386-mingw32]

I have tried this with both ocra 1.2.0 and 1.3.0, and with both ruby 1.8.7 and 1.9.1/2

requiring the tk gem causes lots of failures. Just for fun I started putting rescues around the failure points in the tk code, but it just went on and on. (note removing the require 'tk' allows the exe to be created) Note also none of the tk code is being called. Its just requiring the gem that is causing the problems.

Here are some samples:

=== Loading script to check dependencies
C:/Ruby192/lib/ruby/1.9.1/tk/console.rb:13:in _create_console': interpreter is deleted (RuntimeError) from C:/Ruby192/lib/ruby/1.9.1/tk/console.rb:13:increate'
from C:/Ruby192/lib/ruby/1.9.1/tk/console.rb:15:in `module:TkConsole'

def self.create
TkCore::INTERP._create_console # LINE 13 #
end
self.create # initialize console

putting a rescue at line 13 gets us to:

=== Loading script to check dependencies
C:/Ruby192/lib/ruby/1.9.1/tk/msgcat.rb:24:in <class:TkMsgCatalog>': RuntimeErro r (RuntimeError) from C:/Ruby192/lib/ruby/1.9.1/tk/msgcat.rb:8:in<top (required)>'

st_get'

tk_call_without_enc('package', 'require', 'Tcl', '8.2') # Line 24 #

this problem is repeated a bunch of places in msgcat

and on it goes...

I just wanted to let you know that this is still a problem (I was having trouble with which ocra version I was using, but now that I am definitely using 1.3.0, I am reporting this is still happening.

All I need to reproduce is a file like this:

require 'rubygems'
require 'tk'
puts 'bork!'

Cheers!

I am having the same problem. I am using Ruby 1.9.3 on Windows XP. Program is just:

require 'tk'
puts "hello world"

error is:

Any help would be appreciated. Thanks.

I had to give up, and ended up using fxruby, which actually I liked a lot better.

If you would like more info on where I ended up for the UI on PC email me directly.

Otherwise OCRA works great.

[emalaga]

Good advice, I just installed fxruby using gem and then OCRA built the exe without any problems. I will write my program using fxruby instead of tk. Thanks for your help.

Same issue here, all that is required is a require 'tk' and get this:

While I don't yet have a full understanding of the problem so I don't have a patch, I was able to package Tk with OCRA and distribute it to others as a self-contained exe without the user needing to install anything else. I encountered this issue with Ruby 1.9.2p290 (2011-07-09) [i386-mingw32] on Windows 7. I used the p290 RubyInstaller which packaged the Tk libraries with the Ruby installation. My app was only requiring the following gems: fileutils, tk, and tkextlib/tile.

The problem is OCRA does some autoloading that Tk doesn't like. By adding the --no--autoload flag to the ocra build, it bypasses the attempt_load_autoload error everyone listed above. However, you'll then run into the following error:

C:/TEMP/AppData/Local/Temp/ocr740C.tmp/lib/ruby/1.9.1/tk.rb:36:in `initialize': Can't find a usable init.tcl in the foll
owing directories:  (RuntimeError)
    C:/TEMP/AppData/Local/Temp/ocr740C.tmp/lib/tcltk/tcl8.5 C:/TEMP/AppData/Local/Temp/ocr740C.tmp/lib/tcl8.5 C:/TEMP/....[truncating additional paths, you don't care]

So after some gratuitous use of the --debug-extract flag and experimentation, if you look at C:\Ruby192\lib\\tcltk\tcl8.5\ you should find the init.tcl file, which isn't getting packaged by OCRA since you turned off autoloading. To fix this, you'll now need to add the C:\Ruby192\lib\\tcltk path to your build command as "additional files and resources" as described in the OCRA wiki, and without autoloading, you might need to --add-all-core and twiddle other packaging knobs to make it include everything your app depends upon (mine was a stupid simple app, something with a boatload of dependencies may be more difficult). The obvious downside to this is that your executable file size will increase since you're packaging more stuff. My ~200 line script is a 5Mb executable now.

TL;DR
Try packaging your Tk Ruby app with the following command, it worked for me:

ocra.bat .\lib\main.rb --windows C:\Ruby192\lib\tcltk\ --no-autoload --add-all-core

[larsch]

Upvote for workaround. This is not "fixable" in ocra (at best a workaround could be made automatic):

Use this (same as mattsgarrison suggests):

ocra --no-autoload --add-all-core tkapp.rb c:\ruby193-p392\lib\tcltk

I'm sure this is super late, but in finding my own problem with this, I found bogbasic's comment here which allowed me to use Tk and Ruby with Ocra: https://www.ruby-forum.com/topic/2981846

"Maybe too late but the thing to do is to copy the ruby file you wish to
compile to the C:\Ruby193\lib folder which contains the tcltk directory
and then run ocra there as follows....

ocra yourfile.rb tcltk --no-autoload

... then you can copy the resulting .exe file to wherever you want
afterwards and it runs fine."
