Re: Re: Compilation of arts on HPUX - namespace problems?

Hi,
  In that case, how do I disable testing for aRts in configure? I presume just 
deleting the checks from the configure script will not work, and I did not 
see a --without-arts option.
  Also, does the whole problem exist because the class is defined in the 
header, as opposed to just being declared? If so, I can move the function 
definitions to a different file, and sneak around the compiler.

My interpretation is different: as an object of type ObjectReference is
instanciated the compiler has to see the full definition. As
ObjectReference is only defined in a header that includes common.h I think
the compiler is right and the problem would be non-trivial to fix. Stefan

The simples workaround is just to remove those lines and live without aRts
for now.
