I am installing a Titan2d software (from Buffalo University, Geophysical Mass Flow Group) in cygwin, I make a directory titan-3.0.0 (3.0.0 is the last version), under this directory I run $ sh install-titan.sh

This script will automatically check for both MPI and HDF5 installation. If MPI is not found in its standard location, then the user will be prompted to enter its absolute path, or quit installation. If this script is unable to locate HDF5, then the user will be prompted to enter its absolute path or continue without installing HDF5.

Through the process of installetion I got this error:

Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix.

Alternatively, you may set the environment variables MPICH2_CFLAGS and MPICH2_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details.

make: * No targets specified and no makefile found. Stop. make: Nothing to be done for `install'.

I have installed either the openmpi from the cygwin setup, I choose full package installation so a series of mpi packages are automatically downloaded and installed, as well as I downloaded the last release of mpich-3.0.2 and an older release mpich2-1.2.1p1 and I installed in cygwin with configure, make, make install. However, titan2d installation error tell me that the Package requirements (mpich2-ch3) were not met. I know from the titan2d user guide that "If there are multiple copies of MPI on your machine, this script will find and use the first one in your path". I do not get why my instalaltion comes with this error. Any help will be greatly appreciated
