Now my compilation went down but again stopped at some point.Its halting in awk command after warning config.status: WARNING: '/oss/src/winsup/Makefile.in' seems to ignore the --datarootdir setting awk: ./confXqR7rV/subs.awk:1: BEGIN {\r awk: ./confXqR7rV/subs.awk:1: ^ backslash not last character on line config.status: error: could not create Makefile I have set SHELLOPTS= igncr ,still its give error .
