mpfr configure fails with:
...
checking for recent GMP... yes
checking for __gmpz_init in -lgmp... no
configure: error: libgmp not found or uses a different ABI (including
static vs shared).
Please read the INSTALL file -- see In case of problem.
libgmp seems to be properly installed:
ld.so.cache points to the correct locations for libgmp and libgmpxx, ldd
on both has no missing dependencies, libgmp.la and libgmpxx.la both have
an empty old_library directive (thus i assume both are dynamic only as i
always configure with --disable-static).
neither the INSTALL nor google was of any help - at least none of them
seems to fit my configuration, most were about compiling on apples.
having a closer look at gmp, i had to see some failures during the tests:

as the book reads the tests as critical, i guess the libgmp and/or
libgmpxx might really be broken.
googling about the 'get_d'-failures and the 'assertion failed' mentonied
problems with CFLAGS. as i don't set them, i have no clue where to dig on...
snippet from 'configure' for mpfr:
checking for CC and CFLAGS in gmp.h... yes CC=gcc -std=gnu99 CFLAGS=-m32
-O2 -pedantic -fomit-frame-pointer -mtune=pentiumpro -march=pentiumpro
checking for CC=gcc -std=gnu99 and CFLAGS=-m32 -O2 -pedantic
-fomit-frame-pointer -mtune=pentiumpro -march=pentiumpro... yes
checking for gcc... gcc -std=gnu99
checking whether the C compiler works... yes
same for gmp (ABI=32 ./configure...):
checking whether to enable maintainer-specific portions of Makefiles... no
checking ABI=32
checking compiler gcc -m32 -O2 -pedantic -fomit-frame-pointer ... yes
checking compiler gcc -m32 -O2 -pedantic -fomit-frame-pointer has
sizeof(long)==4... yes
checking compiler gcc -m32 -O2 -pedantic -fomit-frame-pointer
-mtune=pentiumpro... yes
checking compiler gcc -m32 -O2 -pedantic -fomit-frame-pointer
-mtune=pentiumpro -march=pentiumpro... yes
checking for gcc... gcc
checking whether the C compiler works... yes
as far as i understand, the relevant options m32, march and mtune are
the same.
thanks for any help
