编译过程中提示出错:
错误描述

/usr/local/sphinx/src/sphinx.cpp:20078: undefined reference to libiconv’

make: *** [all-recursive] Error 1
===============以下为解决方案=======================================================

原因是g++没有添加 -libiconv选项

cd sphinx-2.2.10-release
vi src/Makefile

把LIBS = -lm -lz -lexpat -L/usr/local/lib -lrt -lpthread
改成
LIBS = -lm -lz -lexpat -L/usr/local/lib -lrt -lpthread -liconv

即可。
