GSOC POSIX Compliance: Stuck trying to build Newlib

[Matthew Joyce]

Hi Vaibhav,

Thanks very much for your note!  Fantastic job on your blogs. I read
the entry on managing the two versions of autoconf and have been
trying to follow it carefully. Could you please see the attached txt
file?

I'm in development/newlib/newlib-cygwin. I get the error where it
tells me to use exactly autoconf 2.64 and not 2.69. I change the $PATH
to make sure it is checking the opt/autoconf-2.64/bin first.

I check the autoconf version and confirm that it is now using 2.64.
But then when I try to run autoreconf -fvi, I get the same error as I
had yesterday.

Do you have any ideas as to what I'm doing wrong?

Thanks again!

Sincerely,

Matt
