The cdef extern from clause does three things:. It directs Cython to place a #include statement for the named header file in the generated C code.; It prevents Cython from generating any C code for the declarations found in the associated block. It treats all declarations within the block as though they started with cdef extern. It’s important to understand that Cython does not itself read

You need to define the full enum in a header file. It still won't work, though, in your case because enums must be numeric -- you can't use a char array. Does anyone know how to use the "extern" declaration correctly for constants and enums?

Extern enum

2011-06-22 · The definition of the enum type must be visible when compiling (and remember: source code files are compiled independently of one another). This is the job header files were born to do. You can put the enum definition and the extern in the header, and any source code that needs to know about it #includes the header.

Its use is implicit. When extern is used with a variable, it’s only declared, not defined. Here's a minimal, but complete example that demonstrates how to refer to an extern enum.
