Hello, I'm trying to build openvrml 0.15.10 which uses the Boost library. However, I get the following error message: /usr/include/boost/numeric/conversion/detail/converter.hpp:233: error: expected unqualified-id before numeric constant /usr/include/boost/numeric/conversion/detail/converter.hpp:238: error: type/value mismatch at argument 6 in template parameter list for 'template<class expr0, class expr1, class TT, class TF, class FT, class FF> struct boost::numeric::convdetail::for_both' /usr/include/boost/numeric/conversion/detail/converter.hpp:238: error: expected a type, got '0l' /usr/include/boost/numeric/conversion/detail/converter.hpp:238: error: 'type' does not name a type which appears to be a problem with the header file. I'm using Linux with gcc 4.0.2. The problematic code from converter.hpp is : template<class PredA, class PredB> struct combine { typedef applyBoth<PredA,PredB> Both ; typedef void None ; //LINE 233 typedef typename PredA::do_apply do_applyA ; typedef typename PredB::do_apply do_applyB ; typedef typename for_both<do_applyA, do_applyB, Both, PredA, PredB, None>::type type ; //LINE 238 } ; Can anyone confirm that there is indeed a problem with the converter.hpp header file? If so, how could it be fixed? Thanks. Regard, Eric Belanger -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
