Hi,
without further testing; this approach may help:
(1) create a shared library with all symbols from libnpymath.a:
$ gcc -shared -o libnpymath.dll -Wl,--whole-archive libnpymath.a
-Wl,--no-whole-archive -lm
(2) create a def file:
gendef libnpymath.dll
There are now two files created by mings

That is not really good enough. Even if we build binary wheels with
MinGW (see link) the binary npymath libr

AFAIK it is a GCC built-in function. When the GCC compiler or linker
sees it the binary code will be inlined.

Hi,
according to

Hi,
Sorry for this ignorant email, but we got confused trying to use
'libnpymath.a' from the mingw builds of numpy:
We were trying to link against the mingw numpy 'libnpymath.a' using
Visual Studio C, but this give undefined symbols from 'libnpymath.a'
like this:
npymath.lib(npy_math.o) : error
