Ubuntu下 安装Protocol Buffers 3.3.0

依赖安装

$ sudo apt-get install autoconf automake libtool curl make g++ unzip

下载

到GitHub下载https://github.com/google/protobuf/releases/下载.或用这地址下载v3.3的 https://github.com/google/protobuf/archive/v3.3.0.zip

$ sudo make install
$ sudo ldconfig # refresh shared library cache.

测试是否安装成功.

protoc --version

正常应该是输出

libprotoc 3.3.0

如果报错提示:

protoc: error while loading shared libraries: libprotoc.so.13: cannot open shared object file: No such file or directory

错误原因

protobuf的默认安装路径是/usr/local/lib,而/usr/local/lib不在ubuntu体系默认的LDLIBRARYPATH里,所以就找不到lib

解决办法

1 在/etc/ld.so.conf.d/目录下创建文件 bprotobuf.conf文件,文件内容如下

/usr/local/lib

2 输入命令

sudo ldconfig

这时,再输入protoc --version就可以正常看到版本号了

$cd ./python 
$python setup.py build 
$python setup.py test 
$python setup.py install
