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 -------------- next part -------------- An HTML attachment was scrubbed...
