Ubuntu系统默认的是gcc 4.8版本：

1
gcc -v

安装4.9, 6.2版本：

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.9 g++-4.9
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.9 60 --slave /usr/bin/g++ g++ /usr/bin/g++-4.9

sudo apt-get install gcc-6 g++-6
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-6 100 --slave /usr/bin/g++ g++ /usr/bin/g++-6

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 50 --slave /usr/bin/g++ g++ /usr/bin/g++-4.8

显示和选择使用版本：

1
sudo update-alternatives --config gcc

首先安装支持库1： 

1
npm install hexo-diagram --save

可能会出现问题： 

1
npm WARN deprecated phantom@0.7.2: v1 is no longer maintained, please upgrade to v2.0+ as soon possible.

导致运行时出现问题：

hexo s
Hexo Diagram Filter
{ diagramFolder: '/Users/luohanjie/Documents/Dropbox/Blogs/source/diagrams' }
Generate: [flow]Robotics/SCARA型机械臂工作区域边界计算方法-diagram-0.png
phantomjs-node: You don't have 'phantomjs' installed

解决方向： 安装最新版phantomjs 

1
npm install phantomjs -g

但是运行时可能会出网络问题： 

1
phantom stdout: NETWORK_ERR: XMLHttpRequest Exception 101: A network error occurred in synchronous requests.

可以通过关闭web-security解决2。将node_modules/hexo-diagram/generators/factory/phantom.js部分代码修改为： 

1
2
3
4
options = { 'web-security': 'no' };

 return function (type, code, output, callback) {
   phantom.create({parameters: options}, function (ph) {

问题解决。

在使用apt-get安装shadowsocks-qt5时1，由于源的版本太老，很多新的协议都不支持。为了支持新的协议，需要自己编译。本文主要参考了这篇文章2。

  • 系统：Ubuntu 16.04.4 LTS
  • 内核：4.13.0-36-generic

编译Botan2.3.0

wget https://botan.randombit.net/releases/Botan-2.3.0.tgz
tar xvf Botan-2.3.0.tgz
cd Botan-2.3.0
./configure.py
make -j4
sudo make install
sudo ldconfig

编译libqtshadowsocks3

Dependencies
  • Qt >= 5.5
  • Botan-2 >= 2.3.0
  • Or Botan-1.10 (Not recommended)
  • CMake >= 3.1
  • A C++ Compiler that supports C++14 features (i.e. GCC >= 4.9)
Building
1

5
6
git clone https://github.com/shadowsocks/libQtShadowsocks
cd libQtShadowsocks
mkdir build && cd build
cmake .. -DCMAKE_INSTALL_PREFIX=/usr
make -j8
sudo make install

编译shadowsocks-qt54

Dependencies
  • cmake >= 3.1.0
  • qt5-qtbase-gui >= 5.2 (qtbase5 in Debian/Ubuntu)
  • qrencode (libqrencode in Debian/Ubuntu)
  • libQtShadowsocks >= 1.10.0 (libqtshadowsocks in Debian/Ubuntu. DON'T use the trunk code)
  • zbar (libzbar0 or libzbar in Debian/Ubuntu)
  • libappindicator (libappindicator1 in Debian/Ubuntu)
Building
1

sudo apt-get install cmake qtbase5-dev libqrencode-dev libzbar0 libappindicator1 libzbar-dev

git clone https://github.com/shadowsocks/shadowsocks-qt5
cd shadowsocks-qt5
mkdir build && cd build
cmake .. -DCMAKE_INSTALL_PREFIX=/usr
make -j8
sudo make install

然后就可以在Ubuntu下找到编译好的shadowsocks-qt5了。
