Hello everyone,

For some reason, I can not run the binary SU2 in parallel on my Windows computer. the ms-mpi never worked properly and SU2_PRT always crashed before the mesh partitioning being started. I also have access to intel-mpi and it has worked flawlessly, but the binary SU2 does not work with intel-mpi.

Anyway, I figured that building from source using intel-mpi is the way to go. After some research I get Cygwin64 installed along with every necessary components to compile and build. The problem is that the installation configuration and settings need to be adjusted to accommodate my Windows OS, and for a Windows user since childhood like me, this seems quite tricky.

After playing with Cygwin for a while, I managed to build the single-threaded SU2 without any optional feature, and yet I consistently get errors when trying to build SU2 with Metis, TecIO, or MPI.

Here below is what I got when trying different configurations.

Any input will be appreciated!

Hi Eric,

I imagine you will have a lot of difficulty compiling SU2 using Cygwin as you have already discovered. This is primarily due to the fact that Cygwin hasn't ported over the full standard C library which SU2 has a number of dependencies on.

Instead, Cygwin has their own implementation of the standard C library called Newlib. Unfortunately, Newlib doesn't have a 1-to-1 equivalent for everything included in the standard C library. As a result, when compiling SU2--especially beginning with some of the external libraries such as metis, tecio, and MPI which rely heavily on the standard C libraries and headers--the compiler is unable to locate specific library or header files because equivalents don't exist in Cygwin's Newlib implementation.

Compiling software under Cygwin in general is therefore somewhat tenuous. You're much better off either creating a UNIX based virtual environment within which you can work from your more familiar Windows surroundings, or install a UNIX-based OS on a separate partition or external drive and dual boot as needed.

Unfortunately, I don't have a better solution for you, but I thought explaining what the underlying problem is might prove beneficial to you, or others who have considered Cygwin as a potential option to running SU2.
