Thank you everyone for your help to my previous query regarding the
installation of GNU Radio on Cygwin. I have checked my fortran 77
compiler and it works fine now( thank you zerocool :)),but now I get
some : “conftest.err : Permission denied " Â and another error which says
" your boost libraries seem too old.” My question is 
1 ) Shall I
ignore the conftest errors because  the conftest.dir, conftest.h and ccp
are created while installing and they automatically are removed
also?Thank you for all your help…I am really happy with the progress
I achieved due to your suggestions!Regards,Reena
