OK, so I can work around this with: ./configure \ ac_cv_lib_gmp___gmpn_zero_p=yes But the test is shady. It does not include the proper header and then looks for a mangled symbol name. If you would have used the proper header then gmpn_zero_p would have been available to you. | /* Override any GCC internal prototype to avoid an error. |Use char because int might match the return type of a GCC |builtin and then its argument prototype would still apply. */ | #ifdef __cplusplus | extern "C" | #endif | char __gmpn_zero_p (); | int | main () | { | return __gmpn_zero_p (); | ; | return 0; | } GMP needs a fair amount of patching on OS X 10.5 due to the extern inline problems. Here's what my patches look like: https://github.com/noloader/Build-Scripts/blob/master/patch/gmp-darwin.patch. It includes a patch for mpn_zero_p. The GMP folks have been aware of the problem for about 15 years but have not fixed it. Also see https://gmplib.org/list-archives/gmp-bugs/2009-May/001423.html. I also wrote to one of the maintainers and offered the patch. "Patches welcome" is utter bullshit in the free software world. I laugh when I see someone use the phrase. I think you should reconsider how you do things. The recommended way to check for a version of the library is with pkg-config. I.e.: pkg-config --libs "gmp >= 6.1.0" I also think you should pay more attention to the dominant use case of nettle+hogweed. It is dominant because distros and users expect/need nettle+hogweed. GnuTLS requires nettle+hogweed. (Can you name anyone who just wants nettle?). The current behavior of silent failure is not appropriate. You should fail configure _if_ GMP is not satisfactory in the absence of --disable-hogweed. Folks who do not want hogweed are _not_ the majority. They should have to do something special like --disable-hogweed. That's good security engineering.

Re: libhgwwed has gone missing...
The last version of Nettle to build and install Hogweed on PowerMac was 3.5. I think this flew under the radar because prefix=/usr/local. Through subsequent upgrades, GnuTLS was picking up the old version of Hogwwed.

It looks like Nettle is no longer building or installing hogweed on some Apple platforms. This is from a PowerMac G5 running OS X 10.5: $ ls /usr/local/lib | grep -E 'gmp|nettle|hogweed' libgmp.10.dylib libgmp.a libgmp.dylib libgmp.la libnettle.8.2.dylib libnettle.8.3.dylib libnettle.8.dylib libnettle.a libnettle.dylib libpari-gmp.dylib It is causing a failure in GnuTLS: checking for NETTLE... yes checking for HOGWEED... no configure: error: *** *** Libhogweed (nettle's companion library) 3.4.1 was not found. Note that you must compile nettle with gmp support. Jeff ___ nettle-bugs mailing list nettle-bugs@lists.lysator.liu.se http://lists.lysator.liu.se/mailman/listinfo/nettle-bugs
