Question

我正在尝试在amazon linux ec2实例上安装opendkim。从源代码编译时我得到： configure：error：找不到strlcpy / strlcat 所以我从源代码安装了libbsd。一旦安装完毕，我可以访问strlcat和strlcpy的手册页，但我无法访问这些功能。我确认已安装共享库。 libbsd安装的输出声明使用4个选项之一：

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'

我跑了

export LD_RUN_PATH=/usr/local/lib
export LD_LIBRARY_PATH=/usr/local/lib/

另外我的/etc/ld.so.conf包含

 include ld.so.conf.d/*.conf

和我的/etc/ld.so.conf.d/libbsd.conf包含

/usr/local/lib/libbsd

最后检查我的libbsd库nm -D /usr/local/lib/libbsd.so包含：

000000000000de30 T strlcat
000000000000ded0 T strlcpy

所以我的问题如何，将strlcat和strlcpy暴露给命令行？或者我如何做＆＃34;使用`-Wl，-rpath -Wl，LIBDIR＆＃39;链接器标志＆＃34;选项，或者一般来说，在链接到共享库时我做错了什么？任何帮助表示赞赏。谢谢！

因此无法链接到库，但我能够解决依赖关系。来自centos的二进制rpm完美安装：

sudo wget http://dl.fedoraproject.org/pub/epel/7/x86_64/l/libbsd-0.6.0-3.el7.x86_64.rpm
 sudo yum localinstall ./libbsd-0.6.0-3.el7.x86_64.rpm

sudo wget http://dl.fedoraproject.org/pub/epel/7/x86_64/l/libbsd-devel-0.6.0-3.el7.x86_64.rpm
sudo yum localinstall ./libbsd-devel-0.6.0-3.el7.x86_64.rpm

链接到linux共享库
