Hi,
This isn't really a deal.II issue but as there are C++ gurus on here, I
thought you could help resolve this.
I just compiled deal.II with the Intel C++ XE compiler. In my code, I've had
to replace all occurrences of std::tr1 with the boost counterpart. However,
for some reason, the compiler has issues with std::pair.
The line of code is:
myMap.insert( std::pair<Tuple, Tuple>( boost::make_tuple(x, y, z),
boost::make_tuple(A, B, C) ) );
Tuple is a typedef:
typedef boost::tuple<double, double, double> Tuple;
myMap is a std:map:
std::map<Tuple, Tuple> Map;
These all worked fine with gcc.
The error I get is:
main.cc(776): error: argument list for class template "std::pair" is missing
myMap.insert( std::pair( boost::make_tuple(x, y, z), boost::make_tuple(A,
B, C) ) );
