Dear Mark,
If "--disable-threads ", how it will influence the function of GROMACS?

By preventing you from running mdrun with a separate execution thread in parallel on each physical processor that your machine has. If you need parallel functionality, compile with MPI enabled.

Secondly, for the webpage you introduced to me "http://www.gromacs.org/Downloads/Installation_Instructions/Cygwin_HOWTO";, "Edit your login files to source /usr/local/gromacs/bin/GMXRC (or manually add /usr/local/gromacs/man to the MANPATH and check that /usr/local/bin is in the PATH)" is a little difficult to me. What is "GMXRC"? What is the login files? How to find the MANPATH? How do I know whther /usr/local/bin is in the PATH is in the path? How can source /usr/local/gromacs/bin/GMXRC?

That page contains the strongly-worded advice to check the normal GROMACS installation instructions, which has a fuller discussion of this "getting access to GROMACS" issue. Please search the web for tutorials and discussion of how UNIX PATH environment variables function.

I am looking forward to getting a reply from you.

I am looking forward to getting your suggestions on how to solve the problem.

The actual error occurred further up, so we cannot give specific help. Be sure you are following the instructions here http://www.gromacs.org/Downloads/Installation_Instructions/Cygwin_HOWTO, in particular --disable-threads.
