Cython std::pair of two pointers, expected an iden

Question

Why in Cython is possible to wrap

std::pair<int, Foo*> myPair;

but not

std::pair<Foo*,Bar*> myPair;

In particular, wrapping in Cython the std::pair is done as follows:

pair[int, Foo*]

and works smoothly, but when the first element of is also a pointer I have problems:

pair[Foo*,Bar*] myPair2

I'm getting

pair[Foo*,Bar*] myPair2
        ^

Answer 1

The types are treated the same in the pair definition; it is probably a general limitation for the [] syntax. You could try to workaround it with a typedef: ctypedef Foo* Foo_pointer
