I am trying to port a small app of mine from Win XP and VS 2005 to Win 7 and VS 2010.
The app compiles and runs smoothly in Debug mode, however in Release mode I get the following error :
pcrecpp.lib(pcrecpp.obj) : error LNK2038: mismatch detected for
'_ITERATOR_DEBUG_LEVEL': value '0' doesn't match value '2' in LoginDlg.obj
The worst part is that I don't know where I should start checking...
Any help will be greatly appreciated.
Your app is being compiled in release mode, but you're linking against the debug version of PCRE, which had /MTd (or similar) set, thus causing the mismatch in iterator debugging level in the CRT.
Recompile PCRE in release mode to match your own application.
The detect_mismatch pragma in VS 2010 is what causes this error to be emitted.
