VS 6 to VS 2010 Conversion - Link Error

Question

0.00/5 (No votes)

I am converting a project from Visual Studio 6 to VS 2010, and the overloaded function: os << m_pos;

gives the following link error:

error LNK2019: unresolved external symbol "class std::basic_ostream<char,struct> > & __cdecl operator<<(class std::basic_ostream<char,struct> > &,class CVector<class> > const &)" (??6@YAAAV?$basic_ostream@DU?$char_traits@D@std@@@std@@AAV01@ABV?$CVector@V?$C1dArray_of_numbers@M@@@@@Z) referenced in function "public: int __thiscall CRestart_file_header::Write(class std::basic_ostream<char,struct> > &)" (?Write@CRestart_file_header@@QAEHAAV?$basic_ostream@DU?$char_traits@D@std@@@std@@@Z)

I am guessing I am missing some library. Any ideas?

I have a small project that shows the code that I could upload, but I am how to do that.

Any help would be greatly appreciated.

Thank you.

Solution 1

(first thought)
Did you replace the STL header files from the old ways (with .h extension) to the new ways (no .h extension) ?

for example
#include <vector.h>
to
#include <vector>

Check all your STL include files.

Question:
What are "os" and "m_pos" ?

Solution 2

There were two friend declarations of both functions that were causing the link errors.
