QUESTION

"unresolved external symbol"-error when linking a Cython extension against a C library on Windows

Asked 2020-Sep-21 at 09:54

I am learning Cython and tried to run a simple example found here: making C library callable.

I used VS 2019 to create mylib.lib and setup.py to build the Cython-extension (for details and code see below), however the linker fails with error:

error LNK2001: unresolved external symbol hello

Yet when I ran nm mylib.lib that I found in other post I can see that the symbol _hello is present:

Rebuild the (static) library for x64.

The symbol in your library is called _hello and not hello as one would expect for a x64-build (your extension is built for 64bit as can be seen in the logs).

On x64, MSVC doesn't mangle names when compiling as C-code so the resulting symbol is simple - hello, but it does mangle C-names on x86 (here documentation, here an example on godbolt.org):

__cdecl-calling convention (default for x86 if no special compile-flags are used) adds prefix _ to the name which would lead to the symbol being called _hello.
__stdcall-calling convention (if compiled with /Gz or the calling convention is explicitly specified, i.e. void __stdcall hello(char *)) adds prefix _ to the name and suffix @ with the number of bytes in the parameter list, i.e. it would lead to _hello@4.

Thus, it becomes clear, that your library is built in 32bit and thus cannot be linked to a 64bit-dll.

Were the library a dll, the symbol's names would be slightly different. Calling

It will not work out-of-the-box with numpy-arrays. You will have to make the memory management yourself, for example:
