编译过程中提示出错:

解决办法：sphinx-2.2.11-release亲测有效:
===============以下为解决方案=======================================================

原因是g++没有添加 -libiconv选项

cd sphinx-2.1.9-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。
