Installing Torch7 on Kubuntu 14.04 LTS x64: "Error: Build error: Failed compiling object readline.o"

Question

我按照 http://torch.ch/docs/getting-started.html 的说明在 Kubuntu 14.04 LTS x64 上的 Torch7 上安装了 Torch。

# in a terminal, run the commands
sudo apt-get install -y cmake # is needed to compile when running ./install.sh
curl -s https://raw.githubusercontent.com/torch/ezinstall/master/install-deps | bash
git clone https://github.com/torch/distro.git ~/torch --recursive
cd ~/torch; ./install.sh

执行 ./install.sh 时失败并显示此错误消息：

Error: Build error: Failed compiling object readline.o

我错过了什么？

要解决此问题，您需要 运行:

sudo apt-get install -y libreadline-dev

然后删除构建文件夹（否则会出现另一个错误：collect2: error: ld returned 1 exit status）并再次运行安装命令。
