MPFR-2.4.1 Check Failures in LFS 6.5 RC2
 

All,

I'm having trouble with the tests for MPFR-2.4.1 in Chapter 6 of the RC. I
didn't get any compilation or compiling errors; they only showed up in the
test suite. The two tests that failed were tset_ld and tcmp_ld. Because
I'm in chapter 6, this shouldn't matter, but my host operating system is
Ubuntu Netbook Remix, which is based on 9.04.

The relevant parts of the check follow:
----------
Error: mpfr_get_ld o mpfr_set_ld <> Id

Thanks in advance for your help.

How I got past this was to copy the GMP and MPFR directories into the GCC directory, like in Chapter 5, and then compile GCC. Most of the checks passed, as is expected by the book. Does anyone here know what the consequences are of compiling GMP and MPFR as part of GCC versus compiling them separately?

Thanks.
