Hi everyone,

I'm trying to install Reef3D on a windows 10 machine. Unfortunately I am not able to install the ubuntu app as it is on a corporate laptop. As a result the windows store is disabled and you can only download the ubuntu app through that, or at least... so it appears to me.

I've come a decent way trying to install it without the ubuntu app. I've installed the the compilers & openmpi using cygwin. I installed the hypre library using cmake and visual studios (following instructions of hypre).

With this setup, I can run "make -j N" in the cygwin terminal and all the different subroutines appear to compile succesfully. Only at the very end, an error is thrown, see the code below. I'm currently stuck here... Does anyone by any chance know how to fix this, and if this can be fixed? It seems some libraries are missing, but google doesnt help me much further. Just wondering if this is a dead end, or still worth pursuing.

Many thanks,
Dirk

Hi Dirk,

We had previously explored Cygwin on windows, but by the time we standardised everything, Ubuntu on windows was available and due to its integration into the windows OS seemed to be the wise choice to make.

The error you paste points to hwloc package not being installed.

use

sudo apt-get install hwloc
(I hope this works on Cygwin but I dont have a machine to verify)
and try compiling again.

For best results, you might want to explore the possibility of a native Unix machine (Linux/ Mac OS)

Hi Arun,

Thanks for your quick response. I was missing a fair number of libraries which were troubling my installation. Ultimately I got it working, thanks for pointing me in the right direction!

Best,
Dirk

Hei MehdiGana,
your problem appears to not be the same as the previously described one. Please do not take over other peoples threads.
