问题描述
我想试用 GnuTLS (3.6.15)。我安装了 p11-kit、荨麻和 gmp。对于 libtasn1 和 unistring，我使用了 ./configure 标志（--with-included-unistring 和 --with-included-libtasn1）。我正在使用的对 ./configure 的完整调用如下所示：./configure --with-included-unistring --with-included-libtasn1 --disable-ssl2-support --disable-cxx.
但是，无论我做什么，在某些时候我都会收到关于 mpn_* 和 mpz_* 的未定义引用的错误。我多次重新安装 gmp 以希望解决问题。我还尝试手动告诉配置使用 -lgmp 标志，并提供了 gmp 的路径。到目前为止，我尝试过的任何解决方案都没有改变一件事。
我正在使用以下命令安装 gmp：
cd gmp-6.2.1
./configure
# which BTW outputs the following:
# configure: summary of build options:

#libtool: link: ( cd ".libs" && rm -f "libgmp.la" && ln -s "../libgmp.la" "libgmp.la" )
sudo make install

#----------------------------------------------------------------------
#Libraries have been installed in:
# /usr/local/lib
#
#If you ever happen to want to link against installed libraries
#in a given directory,LIBDIR,you must either use libtool,and
#specify the full pathname of the library,or use the '-LLIBDIR'
#flag during linking and do at least one of the following:
# - add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
# during execution
# - add LIBDIR to the 'LD_RUN_PATH' environment variable
# during linking
# - use the '-Wl,-rpath -Wl,LIBDIR' linker flag
# - have your system administrator add LIBDIR to '/etc/ld.so.conf'
#
#See any operating system documentation about shared libraries for
#more @R_437_4045@ion,such as the ld(1) and ld.so(8) manual pages.

执行 export LDFLAGS="-lgmp" 之类的操作，然后重试 make 或将其位置提供给 gmp 似乎没有任何改变。我也尝试先执行 make clean，然后在 ./configure 之前立即重试 make。我确实尝试多次重新安装 GnuTLS 和 GMP 没有效果，也重新启动了一次。见鬼，我什至在失败的 sudo make install 之后尝试了 make，它甚至有效，+/-。但是，如果尝试使用 GnuTLS 编译一个简单的 C 程序，引用错误会再次出现，是的，我确实使用 -lgmp 进行了编译。
任何帮助表示赞赏。
使用 GCC 9.3.0。
