std::pair Causing Compilation Errors

[Gennadiy_Rishkin]

Hi,

I just installed the Intel C++ Composer XE 2011. I've replaced all TR1 usage in my code with the Boost versions. However, std::pair is causing me problems.

The line of code is:

myMap.insert( std::pair( boost::make_tuple(x, y, z), boost::make_tuple(A, B, C) ) );

Tuple is a typedef:

typedef boost::tuple Tuple;

myMap is a std:map:

std::map Map;

These all worked fine with gcc.

How can I resolve this?

The error I get is:

main.cpp(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) ) );

Hi Rishkin,

If you want to use boost library with Intel C/C++, you have to build boost library using Intel C/C++ first. As you've known that boost will use the same library for project. For example, boost will call MS library if the project is built with MS VC etc.

Thanks,

You say this line of code is causing the error:

> The line of code is:

> myMap.insert( std::pair( boost::make_tuple(x, y, z), boost::make_tuple(A, B, C) ) );

and yet the error messageshows that the actual line is different:

> main.cpp(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) ) );

Notice in the error message there is no explicit template argument list for std::pair.

Anyway if you can create a preprocessed file that compiles withg++ but not with our compiler please attach it. Use the -E option to create the file.

thanks
