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-w64 tools: libnpymath.dll, libnpymath.def (3) create import libs for MSVC: first open a new command Window with the VC command prompt: > lib /machine:i386 /def:libnpymath.def (for 64bit use: /machine:X64) Microsoft (R) Library Manager Version 9.00.30729.01 Copyright (C) Microsoft Corporation. All rights reserved. Creating library libnpymath.lib and object libnpymath.exp libnpymath.dll, libnpymath.lib and libnpymath.exp should be sufficient for MSVC. libnpymath.dll has to be deployed. -- carlkl 2015-01-01 21:34 GMT+01:00 Sturla Molden <[email protected]>: > On 28/12/14 17:17, David Cournapeau wrote: > > > This is not really supported.
