[linrad] Re: problems getting inpout32.dll working with qt3 forwindows

[Robert McGwier <gmail.com; rwmcgwier@xxxxxxxxxxxxxxxx>]

Roger:

I am somewhat confused since I believe we have incomplete information. 
You mention Qt3.  I have several questions.

Are you using the commercial licensed copy of Qt3 or are you attempting 
to build using Qt3 under MinGW?

If it is the latter,  I really do suggest you use Qt4 but forget that 
for the moment.  Tell us why you are not using Qt4?

Are you able to run MSYS and mingw under Windows XP 64?

WCHAR is a 16 bit unicode character and char is an 8 bit quantity.  You 
are in a bit of a bother I would say.

Thanks,
Bob
