Error compilation

[MedOumza]

Dear All researchers;
I am beginner in OpenLBM. I try to compile the OpenLB code for simple cavity2D. Someone can help me to understand the following message of error:

Thank you in advance

Hello Mohamed,

it looks quite suspicious that your build tries to include “c:\program files\gfortran\include\unistd.h”. Do you by chance have an older MinGW installation on your build machine that is in the PATH?

Searching for your error message points to a MinGW bug that was fixed 3 years ago.

Regards,
Markus
