POGetting Statistics::R to work with PerlApp (or PAR)
text
Body
copied!<p>I'm trying to make an .exe from a simple perl script that uses the Statistics::R package.</p> <pre><code>use Statistics::R; use strict; my $R = Statistics::R->new(); $R->startR; $R->send('x=10'); $R->send('x'); my $ret = $R->read; print $ret; $R->stopR(); </code></pre> <p>Everything works fine until I create the perlapp .exe file. When I test this, I get the following errors:</p> <pre><code>Inappropriate I/O control operation: Win32::Process::Create() at /<C:\@programming\r\trying_r_bridge.exe>IPC/Run.pm line 2105 Inappropriate I/O control operation: Win32::Process::Create() at /<C:\@programming\r\trying_r_bridge.exe>IPC/Run.pm line 2224 Inappropriate I/O control operation: Win32::Process::Create() at /<C:\@programming\r\trying_r_bridge.exe>IPC/Run.pm line 2224 </code></pre> <p>I looked online and found this thread about the problem: <a href="http://www.nntp.perl.org/group/perl.par/2011/05/msg5022.html" rel="nofollow">http://www.nntp.perl.org/group/perl.par/2011/05/msg5022.html</a></p> <p>This is what they say:</p> <blockquote> <p>this happens because the IPC::Run module on Win32 (only) tries to run subprocesses using $^X, which normally contains the path to perl.exe. However, when PAR packs an executable, $^X doesn't happen to point to perl.exe, and so IPC::Run fails at that point. Implementing IPC::Run on Windows without using subprocesses is an unsolved problem.</p> </blockquote> <p>In the end, the thread solution is to use IPC::Run3, which is not an option here.</p> <p>Any suggestions for how to overcome this problem?</p>
