> temporarily unavailableHere is your error. Cygwin does not seem to be able to correctly emulate the position independent nature of shared libraries that is required by the C/OpenMP backend. Instead it appears to have to rebase .so's (much like Windows usually does with .dll's) with the shared libraries themselves being position dependent. The need to explicitly rebase shared libraries does not chime well with dynamic compilation approached used by PyFR. It is quite possibly less work to get the C/OpenMP backend working natively with Microsoft Windows than it is to work around these defects in Cygwin. The CUDA backend has been reported to work successfully and so only a few minor changes related to the eager deletion of shared libraries should be required.
