RE: PDQ Initial setup

It looks like either the PDQ PERL module isn’t installed or failed to install. If you not already, make sure you’ve followed the directions for installing PDQ PERL extension on windows outlined in section 2.1.1 here http://www.perfdynamics.com/Tools/PDQcode.html.

The steps outlined on the perfdynamics site need to be completed successfully for the installation to work -- especially the ones using the dmake command. If those fail, the installation fails. What specific error are you getting when you try issuing the dmake command?

Thanks for your reply.FYI, writing makefile for pdq is successful. do we need to use any specific version of perl?I have followed the below steps.
- set cmd prompt path to perl exe folder.
- run make file
- run the script file test.pl
As per the steps mentioned in perfdynamics site, dmake command is not working for me.Please let me know if pdq folder has to be placed at any specific location.Thank you,Sathish

I downloaded the latest version of Strawberry Perl and was able to get PDQ to compile and run the test script using dmake. Here’s the output:
dmake test
"C:\Strawberry\perl\bin\perl.exe" "-Iblib\lib" "-Iblib\arch" test.pl

However, I did initially run into an environment issue which caused the compile to fail. This or a variant of it might be your problem.
The issue that caused me problems resulted from also having Rtools package installed on my PC with Strawberry Perl. Rtools which comes with its own version of the MinGW compiler toolkit. Strawberry Perl uses a MinGW compiler toolkit to build binary modules. The versions of these kits are different and each produces DLLs produced that are incompatible with the other and won’t link. Because of the order I installed each of the packages, the path to the Rtools MinGW ended up coming before the path to the Strawberry Perl tools in my PATH variable. As a result, my first attempt to build PDQ used the Rtools MinGW tools to build the package, and, as expected, produced DLLs that couldn’t link with Strawberry Perl’s dlls. The fix for this was simple, I swapped the order of the Strawberry Perl tools with the Rtools in my PATH variable, and the build completed successfully.
You might be running into a similar issue. It’s pretty easy to check if this is the case by using the windows “where” command. If you type following into CMD window
>where gcc
The output you should see should look something similar to this
C:\Strawberry\c\bin\gcc.exe
c:\Rtools\gcc-4.6.3\bin\gcc.exe
If the Strawberry Perl version of gcc isn’t found first the dmake will fail. Fix the PATH variable and you should be in business.
