mpfr configure fails on OS X 10.4.11 (i386) due to wrong GMP_NUMB_BITS value

[Moresteck (Moresteck)]

config.log reports that GMP_NUMB_BITS is 64 somehow, even though in gmp.h it's defined as 32.

configure:18688: ./conftest
GMP_NUMB_BITS     = 64
sizeof(mp_limb_t) = 4
sizeof(mp_limb_t) * CHAR_BIT = 32 != GMP_NUMB_BITS
configure:18688: $? = 1
configure: program exited with status 1

configure:18694: result: no
configure:18696: error: GMP_NUMB_BITS and sizeof(mp_limb_t) are not consistent.
You probably need to change some of the GMP or MPFR compile options.
See 'config.log' for details (search for GMP_NUMB_BITS).

Maybe gmp is built incorrectly, or maybe the blame is on mpfr?

Attached are full config.log, main.log and terminal output from trying to install libarchive.

how is gmp installed? Universal?

if GMP_NUMB_BITS in gmp.h is 32, yet mpfr is finding it as 64, then that is what is to be sorted out.

might you have another gmp.h somewhere then, like in /usr/local?

Thank you, that was indeed the case. I forgot that I tried to install libarchive manually like a year ago... Apologies.

Excellent! I love easy fixes...
