namespaced cast patch

Created attachment 12 [details]
ascii cast patch

There are two possible reasons why it fails on your box. Either your compiler 
fails to cast to the namespace-ed RIFF::String (which is actually just a 
typedef for std::string). In that case try the uploaded "namespace cast patch" 
first. 
 
Otherwise if that didn't work, I guess you compiled Qt with QT_NO_STL. In that 
case you would have to use the solution as shown in the uploaded "ascii cast 
patch". 
 
Let us know which one of them works! 

Sorry for the long delay.  I got your response while on vacation, set it aside
to deal when on my return, and then immediately forgot about it.

Thanks for the response.  Either patch seems to fix the original error, but now
I get a similar looking one for another file. The new error is included below.

I'm running slackware-10.1, with the default packaged versions of qt and gcc:

qt-3.3.3, compiled with: 
	  echo "yes" | ./configure \
	   -prefix /usr/lib/qt \
	   -release \
	   -system-zlib \
	   -system-libpng \
	   -qt-imgfmt-png \
	    -system-libmng \	 
	    -qt-imgfmt-mng \	 
	    -system-libjpeg \	 
	    -qt-imgfmt-jpeg \	 
	    -qt-gif \		 
	    -thread \		 
	    -no-stl \		 
	    -no-g++-exceptions \	 
	    -xft \			 
	    -plugin-sql-mysql \	 
	    -plugin-style-cde \

	    -plugin-style-motifplus 
	    -plugin-style-platinum \
	    -plugin-style-sgi \	 
	    -plugin-style-windows \ 
	    -enable-opengl          


 
gcc 3.3.4, compiled with 
    ../gcc-$VERSION/configure --prefix=/usr \
              --enable-shared \
              --enable-threads=posix \
              --enable-__cxa_atexit \
              --disable-checking \
              --with-gnu-ld \
              --verbose \
              --target=${TARGET} \
              --host=${TARGET}


I take it the "-no-stl" option is causing trouble here?  Is that an unusual
configuration? 

I decided to try building qt without that option, but it looks as though it's
not going to be done until well after I've gone to bed.  Will have to see if it
works tomorrow.  (And whether I can try it out without breaking every other QT
app in the process. . . )


Here's the new error message:

Thanks again,

Ok, I believe this issue should be fixed with latest CVS version of QSampler. 
Please let us know if that works for you now. 

Closed, since assuming fixed and no reply from original reporter.
