Re: Configuration problem: not recognizing MPFR

I am attempting to configure gcc-4.5-20090507 on Mac OS 10.4 using the command

issued from inside a directory at the same level in the directory tree

checking for correct version of gmp.h... yes
checking for correct version of mpfr.h... no

It checks the header version, not the library version !


configure: error: Building GCC requires GMP 4.2+ and MPFR 2.3.2+.

My MPFR version is 2.4.1 and when I run "make check" inside the
mpfr-2.4.1 directory, I get the response
-----------
All 148 tests passed
----------

Have you installed this ? Where the 'mpfr.h' went?


Inside /usr/local/lib, I have the files

$ls libmpfr.*
libmpfr.1.dylib libmpfr.a       libmpfr.dylib   libmpfr.la

Where is the 'mpfr.h' giving the error message?


Can someone advice me as to how to get gcc to recognize my mpfr libraries?

Again, the question wasn't about the mpfr library but about the mpfr header! Some older 'mpfr.h' header probably found earlier...
