我正在尝试建立GnuTLS http://www.gnu.org/software/gnutls/在 Mac OS X 10.5 (Leopard) 服务器上（是的，我知道，它有点过时，但这就是该服务器目前正在运行的）并且遇到了构建问题Nettle http://www.lysator.liu.se/~nisse/nettle/: 我已经构建并安装了GMP http://gmplib.org/，但是荨麻的configure找不到。
我构建并安装了 GMP 5.0.2，如下（GCC 版本解决方案来自here http://gmplib.org/list-archives/gmp-bugs/2010-January/001838.html):
curl -O ftp://ftp.gmplib.org/pub/gmp-5.0.2/gmp-5.0.2.tar.bz2
tar xjf gmp-5.0.2.tar.bz2
pushd gmp-5.0.2
CC=gcc-4.2 CXX=g++4.2 ./configure --prefix=/usr/local
make
sudo make install
popd
A make check通过了所有测试，我最终安装了以下 GMP 文件：
/usr/local/include/gmp.h
/usr/local/lib/libgmp.10.dylib
/usr/local/lib/libgmp.a
/usr/local/lib/libgmp.dylib
/usr/local/lib/libgmp.la
/usr/local/share/info/gmp.info
/usr/local/share/info/gmp.info-1
/usr/local/share/info/gmp.info-2
但是，当我尝试构建 Nettle 2.4 时，如下所示：
curl -O http://www.lysator.liu.se/~nisse/archive/nettle-2.4.tar.gz
tar xzf nettle-2.4.tar.gz
pushd nettle-2.4
./configure --prefix=/usr/local
make
sudo make install
popd
它构建并安装成功，但无法构建libhogweed因为缺少 GMP。经过进一步检查，我发现以下警告configure output:
checking for __gmpz_getlimbn in -lgmp... no
configure: WARNING: GNU MP not found, or not 3.1 or up, see http://gmplib.org/.
Support for public key algorithms will be unavailable.
checking for __gmpz_powm_sec... no
显然，GMP 5.0.2 比 3.1 更新，而且 '__gmpz_getlimbn' 和 '__gmpz_powm_sec' 都定义在/usr/local/include/gmp.h，所以关于我的 GMP 安装的一切似乎都是正确的。
我尝试过各种configure选项（特别是寻找某种类型的“--with-gmp”选项）无济于事。我也尝试过使用相同版本的 GCC (CC=gcc-4.2 CXX=g++4.2 ./configure --prefix=/usr/local）就像我编译 GMP 一样，结果没有变化。--includedir & --libdir应设置为$PREFIX/include & $PREFIX/lib分别（特别是因为我没有指定--exec-prefix）所以我不明白为什么它找不到 GMP。
任何建议都会greatly赞赏。
Update:
我在中找到了以下内容config.log解释找不到 GMP 的原因：

Running file /usr/local/lib/libgmp.dylib返回以下内容：
/usr/local/lib/libgmp.dylib: Mach-O 64-bit dynamically linked shared library x86_64
该服务器运行的是 Intel Core 2 Duo 处理器，因此 64 位 Mach 库对我来说看起来是正确的。我不知道如何判断 nettle 是为 32 位还是 64 位架构构建，所以我尝试了CC=gcc-4.2 CXX=g++4.2 ABI=64 ./configure --prefix=/usr/local没有变化（而且，即使指定ABI=32荨麻的configure总是说“ABI：标准”...它没有通过 ABI 吗？）。
Would re-compiling GMP as a static library make any difference? (Nope, GMP builds both static & dynamic libraries, by default. I listed both above when showing all the installed files.)
