In my timeplan the next mingwpy PR on numpy master is anticipated to take place at the weekend, together with a build description. This PR is targeted to build numpy with OpenBLAS. Carl 2016-01-27 16:01 GMT+01:00 Ralf Gommers : > > > On Wed, Jan 27, 2016 at 3:51 PM, G Young wrote: > >> I don't

I don't need it at this point. I'm just going through the exercise for purposes of updating building from source on Windows. But that's good to know though. Thanks! Greg On Wed, Jan 27, 2016 at 2:48 PM, Ralf Gommers wrote: > > > On Wed, Jan 27, 2016 at 3:19 PM, G Young wrote: > >> NumPy wil

NumPy will "build" successfully, but then when I type "import numpy", it cannot import the multiarray PYD file. I am using dependency walker, and that's how I know it's the libopenblas.dll file that it's not linking to properly, hence my original question. Greg On Wed, Jan 27, 2016 at 1:58 PM, M

When you say find/use, can you please clarify whether you have completed the compilation/linking successfully? I'm not clear on exactly when you're having problems. What is the error output? One very helpful tool in diagnosing dll problems is dependency walker: http://www.dependencywalker.com/

I do have my site.cfg file pointing to my library which contains a .lib file along with the appropriate include_dirs parameter. However, NumPy can't seem to find / use the DLL file no matter where I put it (numpy/core, same directory as openblas.lib). By the way, I should mention that I am using

I'm not sure about the mingw tool chain, but usually on windows at link time you need a .lib file, called the import library. The .dll is used at runtime, not at link time. This is different from *nix, where the .so serves both purposes. The link you posted mentions import files, so I hope this

Hello all, I'm trying to update the documentation for building Numpy from source, and I've hit a brick wall in trying to build the library using OpenBLAS because I can't seem to link the libopenblas.dll file. I tried following the suggestion of placing the DLL in numpy/core as suggested here

Hi Sergey: I recently ran into similar problems with ACML. See an original bug report (https://github.com/numpy/numpy/issues/2728) & documentation fix (https://github.com/numpy/numpy/pull/2809). Personally, I ended up using a patch similar to https://github.com/numpy/numpy/pull/2751 to force
