Making install in libspeex

.././install-sh -c -d '/usr/local/lib'

/bin/sh ../libtool --mode=install /usr/bin/install -c libspeex.la '/usr/local/lib'

libtool: install: /usr/bin/install -c .libs/libspeex.1.dylib /usr/local/lib/libspeex.1.dylib

libtool: install: (cd /usr/local/lib && { ln -s -f libspeex.1.dylib libspeex.dylib || { rm -f libspeex.dylib && ln -s libspeex.1.dylib libspeex.dylib; }; })

2.打包

> cd pathto/release

linux系统:

> make -f makefile-linux

> make -f makefile-linux install

mac系统:

> make -f makefile-mac

> make -f makefile-mac install

3.测试

SpeexUtils.decode("pathto/a.speex", "pathto/a-test.wav");
