编译出错

Digeo_Lavine

用源码编译安装libffi，configure正确，make&&make install时出现
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 information, such as the ld(1) and ld.so( manual pages.

如何解决

chenyx

没有错误信息,你编译已经通过了.
你给出的信息是提示信息,提示你库文件安装的位置,让你将/usr/local/lib路径写到/etc/ld.so.conf文件里面去,如果里面已经有了,执行下ldconfig就好了.

Digeo_Lavine

ld.so.conf文件里面有：include ld.so.conf.d/*.conf。是否可以直接在后面写/usr/local/lib呢？写完后是不是还要重新编译？

chenyx

在/etc/ld.so.conf.d/目录下看看*.conf文件里面有没有哪个文件里面有/usr/local/lib,如果都没,新建一个或者在某个文件里面写一行,然后执行下ldconfig执行下就可以了
