I am using gmp-4.2.4 & mpfr-2.4.1. OS - Mac OS X v 10.5.7 I am trying to compile GCC-4.4.1. But the error that I get is "checking for correct version of mpfr.h... no". I configured MPFR into /pkg/mpfr-2.4.1 & GMP into /pkg/gmp-4.2.4. Then Make , make check , make install .. nothing gave error. But while compiling GCC I get this error. I manually found out the location of mpfr.h. It's in /pkg/mpfr-2.4.1/include. Please help me out with this. I think this is a quiet common problem with no structured solution :( -- Ankit Mahanot -- Ankit Mahanot Sent from Delhi, DL, India
