perl-web-script should start a application with wine

Andreasus · Post by **Andreasus** » Tue Dec 16, 2008 9:49 am

I need some help.

I have a windows application which load a file, do something and put the output in the same file. This tool is called ct.exe. Now I use wine to start this application, everything works fine.

My problem starts if a try to write a perlscript which start this wine application.

my perl script:
1 #!/usr/bin/perl
2
3 use strict;
4 use CGI;
5 use CGI::Carp qw(fatalsToBrowser warningsToBrowser);
6
7 my $cgi = new CGI;
8 my $html = q();
9
10 print $cgi->header(q(text/html));
11 print $cgi->start_html(-title => q(lustiger wine test)),
12 $cgi->h1(q( is not an Emulator)),
13 my $output = exec("wine /usr/share/weblicgen/bin/ct.exe
14 -open /usr/share/weblicgen/bin/coreTechLeer.lic ");
15 print "$output";
16 $cgi->end_html();
17 print $html;

Error_log:
191 [error] [client 10.113.201.215] fixme:actctx:parse_depend_manifests Could not find dependent assembly L"Microsoft.VC80.CRT"
192 [error] [client 10.113.201.215] Application tried to create a window, but no driver could be loaded.

Note: If I type: perl webscript.pl, then It works. If I write this script as a normal perlscript without using it from a browser, then it works too.

Can someone help me?

Most likely there are two things. First of all msvcrt80.dll could be missing. Second as the error says no display driver can be found (wine's x11 driver). A lot of apps even if they appear commandline only require a display driver because they require functionality from it while they aren't showing a window themselves.

Likely when you were executing the script by hand you had a display variable set, so that winex11.drv could be loaded.

Thank you for the answer.

Unfortunately the msvcrt80.dll is in /var/www/ (which should be the home directory for apache) and a web application is not able to start a x server ? Am I right?

You don't need a real Xserver which is connected to a monitor. For instance you could use Xvnc or whatever. Is there no other way to do what you need? Starting wine and then closing it again is a relative heavy operation if it needs to happen frequently. The first thing I would test is if you really need X. Try to run script without a display variable (e.g. when you are in a terminal outside X) as a normal user.

This won't work. You have to properly install vc2005 redist. You can use winetricks to install it as well

You need a valid X session. It doesn't have to be started by your web application. But it have to be able to connect to it:
- DISPLAY env var needs to point to it
- X session needs to allow connections from anyone (xhost +)

How can I install vc2005 ?

I tried:
