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

I followed the instructions from http://torch.ch/docs/getting-started.html to install Torch on Torch7 on Kubuntu 14.04 LTS x64.

# 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

When executing ./install.sh it failed with this error message:

Error: Build error: Failed compiling object readline.o

What did I miss?

Solution

  • To fix this issue you need to run:

    sudo apt-get install -y libreadline-dev

    then remove the build folder (otherwise it will give another error: collect2: error: ld returned 1 exit status) and run the installation commands again.
