I have spent long hours googling on this subject and trying the
various suggestions presented, but so far none have worked. I also
have emailed Apple's XCode mailing list, hoping to find a solution
without bothering the gmp community, but was unsuccessful. I also
searched through the last year of archives on this list.
When I compile gmp 4.2.4 (32-bit) on OS X 10.5.4 I get:
duplicate symbol ___gmpz_abs in /Users/wwilliam/Development/code/
project/build/Debug/libcrypt.a(crypt.o) and /Users/wwilliam/
Development/code/project/build/Debug/libcrypt.a(rsa.o)
My understanding from my searches is that this due to a bug in Apple's
inline implementation.
Defining __GMP_FORCE_mpz_abs got rid of this error, but then the same
error occurred with with __gmpz_fits_uint_p. Defining
__GMP_FORCE_mpz_fits_uint_p did not resolve that error, leading me to
worry that I didn't truly understand the issue and changing things at
random was not a good idea.
I'm hoping this issue has been seen before and there's a simple
solution that I'm just missing.
Thanks,
Wade
