Hi Satish, I have installed cygwin yesterday, and this is the output I have:
cygcheck.exe -f /usr/bin/mpicxx openmpi-3.1.3-1 mpicxx -show g++ -fexceptions -L/usr/lib -lmpi_cxx -lmpi -lopen-rte -lopen-pal -lm -lgdi32 As you can see, my installation for some reasons requires libmpi_cxx. Do you have an idea how can this be solved? Michael.
