安装libevent2执行 make install时报错：

Question

Libraries have been installed in:
   /usr/local/memcached/libevent-2.1.12-stable/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 information, such as the ld(1) and ld.so(8) manual pages.

使用 sudo make install 也是同样的错误

Answer 1

根据错误提示信息，您安装的libevent2相关文件已经被安装到了指定的目录，但是在执行make install的过程中出现了错误，提示在安装头文件时遇到了同名文件的情况。

这种情况可以考虑手动删除已经存在的/include目录下的文件，再重新执行make install命令。

另外，建议您在执行make install命令时，使用全路径来指定libevent库文件的位置，或者使用LD_RUN_PATH/LD_LIBRARY_PATH等环境变量来指定libevent库文件的路径，以避免链接错误等问题。
