Errors building JUCE 1.8 with vcexpress

General JUCE discussion
1

I tried to build JUCE 1.8 with the latest Visual C++ EXpress (Feb 2005 release) and got many errors related to strings. I switched back to JUCE 1.7 and got the same errors with the new VC, any idea what to do, can JUCE be fixed or is it a problem with the new VC?

ah, I didn’t know there was a new VC version out. I’ll have a go asap…

Its not a new public beta but a developer preview release from Feb 2005. Look below the beta version for the link. The previous Preview (Oct 2004) was very bad so I removed it but this one works great except for these errors. Since it works ok with other projects I suspect it relates to JUCE maybe.

thanks

ok, I’ve got the latest one now. Easy to fix this: in platformdefs.h, line 132, get rid of all this:

  typedef wchar_t           juce_wchar;

  /** A platform-independent unicode character type. */
  typedef unsigned short    juce_wchar;

…and replace it with just:

  typedef wchar_t           juce_wchar;

Thanks! It now compiles and works on both debug and release :slight_smile:
