Getting wxPerl::Constructors error.

Hi All,

I am getting an error while running the Perl program on the windows. I have done the IPC::Run for this and the log is good with the successful installation of the module. Please help.
Please see below.
C:\Documents and Settings\xyz\Desktop\Perl>winframe.pl
Can't locate wxPerl/Constructors.pm in @INC (@INC contains: C:\Users\xyz~1\perl5\lib\perl5\MSWin32-x64-multi-thread C:\Users\xyz~1\perl5\lib\per

The error message is telling you that it can't find the wxPerl::Constructors module. So, either it isn't installed or it wasn't installed correctly.

What do you mean by this:


How did you install the module?

Correct. I could not able to install it properly. This is basically on windows. Initially, I had the problem with installing the Wx into my system by getting an error 'wxbase28u_gcc_custom.dll Error'. But then found out that I have missed the Alien to be installed, which is the Wx is dependent on. Then the problem is solved. Later on, I have installed wxPerl::Constructors into my system and executed a sample program to see if it works. The console throwing an error as described before. I have installed the module from CPAN.

Just now, I tried to install wxPerl::Constructors::argmap, please see the error below.

It looks like you have 2 different installations of perl on your system. That is not a problem on *nix systems, but is a problem on Windows systems.

Windows systems can be configured to utilize multiple perl installations by using perlbrew or a VM. However, if you're new to perl, I wouldn't recommend going that route because that adds another layer of complexity.

Personally, I'd remove both/all perl installations and then reinstall a single instance of perl. I normally use Activestate, but others would recommend Strawberry perl.

You are absolutely right. I have two different installations. The ActivePerl that I have initially installed and was successfully running in my system, but due some blogs and googled information I have installed Strawberry Perl on my system, which led to this confusion. Just a little clarification, if I remove and reinstall a newer Perl, should I keep my old scripts as they are. I think I also need to reinstall all the modules, which I have installed previously. I do not know what would be outcome of uninstalling the Perls from my system. Anyway, I will remove all the Perl installations from the Control Panel and install a new Active Perl.

After uninstalling via Add/Remove Programs, there still will be some left over files/directories that you'll need to manually delete before reinstalling perl.

You will , of course, want to be sure not to delete your scripts and you will need to reinstall all modules that are not core and are not included as part of Activestate.

One thing to keep in mind about Activestate when deciding on which perl disto to install is that a lot of modules which are not included in Activestate's repository can be difficult to install. Strawberry perl is much better at installing a wider range of cpan modules.

True, I was just going to ask the same.
Do you think DWIM or Citrus Perl would be a better idea to install? I am asking this just in case, if they might be of good use for the GUI on windows that I am working with right now. So far, I have read and heard that the StrawberryPerl is good for Windows and ActivePerl is rather a bit complex on windows and more than that they wanted to push the Devkit for selling (don't know if it is real or not.)

I've never worked with DWIM or Citrus Perl, so I can't answer that part of your question.

I just checked my Win7 32 bit system here at work using Activestate perl 5.14 and it only has about 5 Wx related modules and the ones you're trying to install are not in that list.

For your purposes, it might be best to use Strawberry perl instead of Activestate.

I have just tried to remove both the perls and re-install the strawberry, but just in case I asked one of my co-worker of what he is using on his machine for windows and he told me that he is using Active Perl. But then I have tried installing the Wx and wxPerl::Constructors on my machine again, which I have already tried it earlier and the console threw the error message as below.

Please look into this.
C:\Perl64>cpan

Enter 'h' for help.

So, did you install Strawberry perl or Activestate perl as the error message appears to indicate?

If you installed Activestate, then use its ppm utility.



Then install MinGW


Then use cpan to install wxPerl::Constructors

When I have tried doing the Wx through ppm, it threw an error. Here is the error below.

C:\Users\psr>ppm install Wx
Unrecognized proxy setting "http_proxy=http://psrassword@proxy.10.155.10.129" ignored.
The http_proxy environment variable should be of the form "http://proxy.example.com".
No missing packages to install

Have you tried correcting or removing the http_proxy environment variable?

I have modified it before as it was set to Port # 80 in the LAN Settings and set the address to http://ppm.activestate.com/CPAN. I was trying to install the Wx through CPAN for ActiveState. Don't know if it works or not, but just tried as trial and error method.

That's the wrong value to set for the proxy.

Unless your internet connection requires the use of a proxy server, which may be the case in a corp environment, then there is no need to set that environment variable.
