Hi All,
I've recently installed latest x-Cygwin on different PCs and suddenly
discovered strange reaction on 'system' function inside Perl/Tk apps.
Naturally, console applications running well with this function.
Below you can see my snippet code and stuff it prints.
FELIX-XP cat test.pl
#!/usr/bin/perl
# Code automatically generated by VPTK_W
use strict;
use Tk;
use Tk::Button;
my $mw=MainWindow->new(-title=>'Bug demo');
my $w_Button_001 = $mw -Button ( -background=>'green4',
-foreground=>'Yellow', -text=>'Exit', -command=>sub {exit} ) -pack();
my $w_Button_002 = $mw -Button ( -background, 'Yellow', -foreground,
'Black', -command, sub{system('echo Hello'=>'')}, -text, 'Magic 0' )
-pack();
my $w_Button_003 = $mw -Button ( -background, 'Red', -foreground,
'Yellow', -command, sub{system('xterm'=>'')}, -text, 'Magic 1' ) ->
pack();
MainLoop;
and signed with the name
Felix, which
jesuashok removed:
Any help/suggestion will be highly appreciated,
Felix.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
