in thread mysql installation w/cpan

The first thing to check is that your compiler is in your path. Not that that is any guarentee that the EU:MM tools will "find" it.

I recently encountered a problem with building a module (threads) where the EU::MM generated makefile refused to do anything, because it decided I didn't have a compiler.

Turned out that it was trying to use -x 'cl' to determine if the compiler existed and was executable, which is never going to work as the file is cl.exe. I bypassed the problem by just commenting out the dumb test and it went ahead successfully.

You could try doing: 

perl -d:Trace c:\yourPerl\bin\cpan.bat

[download]

to try and track down where (and what it is doing), to decide you don't have a compiler. But to do that you'd need to have Devel::Trace installed, which you probably don't. Catch22.

However, Devel::Trace is a very simple module and can be installed manually by downloading this file into c:\yourPerl\lib\Devel\ directory.

      Sorry, I was assuming you were using AS perl. If not, do the same thing, but on cpan.pl:

      Note:Your output will be somewhat different because I've tweaked my copy a few times.

      And once you get to the prompt, attempt your install in the normal way:install the::package.

      When it bottles out with the "Can't find your compiler", the last dozen or so lines will show you why. If you have trouble interpreting it, post them (say the last 30 or so) here, and someone maybe able to help you.
