Question

I’m learning about boost multiIndex and I’m following this tutorial.

The problem is that I cannot compile the code from the Hashed Indices section (the first block of code on that page) using Visual Studio 2008 🙁

Every time I try, the c++ compiler complains:

main.cpp(19) : error C2143: syntax error : missing ';' before '<'
main.cpp(19) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

Those errors occur at the typedef on line 19 in the block of code shown above. Can someone help me shed some light on this please?

Answer 1

The code in that example has an implied using directive — using namespace boost::multi_index;.

Either add said using directive before the typedef, or fully qualify multi_index_container, indexed_by, ordered_unique, hashed_unique, etc.
