Problems with using Ocra

Ruby
1

I try to create EXE file by Ocra. I have Tk in my script:

require ‘tk’
require ‘tkextlib/tile’

root = TkRoot.new {title “Feet to Meters”}
content = Tk::Tile::Frame.new(root) {padding “3 3 12 12”}.grid( :sticky
=> ‘nsew’)
TkGrid.columnconfigure root, 0, :weight => 1; TkGrid.rowconfigure root,
0, :weight => 1

$feet = TkVariable.new; $meters = TkVariable.new
f = Tk::Tile::Entry.new(content) {width 7; textvariable $feet}.grid(
:column => 2, :row => 1, :sticky => ‘we’ )
Tk::Tile::Label.new(content) {textvariable $meters}.grid( :column => 2,
:row => 2, :sticky => ‘we’);
Tk::Tile::Button.new(content) {text ‘Calculate’; command
{calculate}}.grid( :column => 3, :row => 3, :sticky => ‘w’)

Tk::Tile::Label.new(content) {text ‘feet’}.grid( :column => 3, :row =>
1, :sticky => ‘w’)
Tk::Tile::Label.new(content) {text ‘is equivalent to’}.grid( :column =>
1, :row => 2, :sticky => ‘e’)
Tk::Tile::Label.new(content) {text ‘meters’}.grid( :column => 3, :row =>
2, :sticky => ‘w’)

TkWinfo.children(content).each {|w| TkGrid.configure w, :padx => 5,
:pady => 5}
f.focus
root.bind(“Return”) {calculate}

def calculate
begin
$meters.value = (0.3048*$feet*10000.0).round()/10000.0
rescue
$meters.value = ‘’
end
end

Tk.mainloop

that is what I’ve got in my console:

Can anyone please help me to solve this problem?

Have a look at the switches you can use with Ocra. I had to try several
times before it worked and I don’t have the code in front of me, but
this was the first suggestion I found when looking online:

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

Add in your own script & tk directory.

It worked! Thank you! It seems I’m not good in searching solutions :slight_smile:
