Error while building Qt 5.3

When I want to build Qt 5.3 on Windows, it give me an error:

mingw32-make[4]: Entering directory 'c:/qt-5.3.0/qtbase/src/corelib'

And there is lot of errors related to PCRE after that.

I found that the PCRE library is related to Perl, but Perl is correctly installed on my PC.

Do you have a solution?

Solution

You must have a broken installation. Strive for a clean new installation.

This works fine with the pcre.h installed. I would suggest to reinstall your setup because even though if you replace your stray pcre.h file, other things may as well just blow up at some point.
