最近要做一个音乐相关的客户端，其中一个功能是音乐识别，搜索了一些资料选择Echoprint来开发，Echoprint是开源免费的，而且多种客户端都支持能节约很多时间，今天主要下载和编译源码以及测试。(备注：我的开发环境是Mac，所以下面以及之后都是Mac的环境)

1、官网

官网地址：http://echoprint.me

2、安装依赖环境

• 首先安装HomeBrew
• 安装依赖库 

  brew install ffmpeg boost taglib

  安装的目录都在

  /usr/local/Cellar

3、下载源码

git clone -b release-4.12 git://github.com/echonest/echoprint-codegen.git

adsl-172-10-1-12:~ zhangjie$ cd echoprint-codegen

adsl-172-10-1-12:echoprint-codegen zhangjie$ cd src/

adsl-172-10-1-12:src zhangjie$ vim Makefile 

BOOST_CFLAGS=-I/usr/local/Cellar/boost/1.58.0/include

 34 libcodegen: $(MODULES_LIB)

 35 ifeq ($(UNAME),Darwin)

 36         libtool -dynamic -flat_namespace -install_name libcodegen.$(VERSION).dylib -lSystem -compatibility_version $(VERSION_COMPAT) \

 37                 -macosx_version_min 10.6 -current_version $(VERSION) -o libcodegen.$(VERSION).dylib -undefined suppress \

 38             $(MODULES_LIB) -framework vecLib -framework Accelerate

 39 else

 40         $(CXX) -shared -fPIC -Wl,-soname,$(SONAME) -o $(LIBNAME).$(VERSION) $(MODULES_LIB) -lz

 41 endif

变为如下：

 34 libcodegen: $(MODULES_LIB)

 35 ifeq ($(UNAME),Darwin)

 36         libtool -dynamic -flat_namespace -install_name libcodegen.$(VERSION).dylib -lSystem -compatibility_version $(VERSION_COMPAT) \

 37                 -macosx_version_min 10.6 -current_version $(VERSION) -o libcodegen.$(VERSION).dylib -undefined suppress \

 38             $(MODULES_LIB)  -framework Accelerate

 39 else

 40         $(CXX) -shared -fPIC -Wl,-soname,$(SONAME) -o $(LIBNAME).$(VERSION) $(MODULES_LIB) -lz

 41 endif

4、编译

编译后会在src同级目录下生成一个echoprint-codegen二进制文件

Usage: ./echoprint-codegen [ filename | -s ] [seconds_start] [seconds_duration] [< file_list (if -s is set)]

./echoprint-codegen ~/Desktop/Maps.mp3 10 20
