DEar All, Here is out put from Python console after runing teh suggested Python code script.
>>> import os >>> print os.path.realpath(os.getcwd()) C:\Python27 >>> print os.path.realpath(os.environ['SLEPC_DIR']) D:\TEST_FOLDER_dell\slepc >>> Interesting thing here is, why Python script returns the backslashed path although I'm sure that I set it in? environmental ?variables as forward slashed path.? And here is the output from the CygWin terminal? nobody at nobody /cygdrive/d/TEST_FOLDER_dell/slepc $ export SKPEC_DIR=D:/TEST_FOLDER_dell/slepc/ nobody at nobody /cygdrive/d/TEST_FOLDER_dell/slepc $ ./configure Checking environment... cygwin warning: ? MS-DOS style path detected: D:/TEST_FOLDER_dell/slepc ? Preferred POSIX equivalent is: /cygdrive/d/TEST_FOLDER_dell/slepc ? CYGWIN environment variable option "nodosfilewarning" turns off this warning. ? Consult the user's guide for more details about POSIX paths: ? ? http://cygwin.com/cygwin-ug-net/using.html#using-pathnames ERROR: SLEPC_DIR is not the current directory Your help will be appreciated,
