问题：

  在程序测试中发现报下面的这个错误

   soxmix: error while loading shared libraries: libippsc.so: cannot open shared object file: No such file or directory

  这个程序是在64位平台下进行的编译，64位平台的库的名字已及路径： /opt/intel/ipp41/em64t/sharedlib/libippscem64t.so  

在Makefile编译时的链接环境：

IPPROOT = /opt/intel/ipp41/em64t
LIB_G729  = -L./libg729 -L$(IPPROOT)/sharedlib -L$(IPPROOT)/sharedlib/linuxem64t -lg729 -lippscem64t -lipp

ld.so.conf内容：

include ld.so.conf.d/*.conf
/opt/intel/ipp41/em64t/sharedlib
/opt/intel/ipp41/em64t/sharedlib/linuxem64t

使用readelf  -d soxmix 命令查看库的链接情况:

[root@localhost src]# readelf -d soxmix
