Question How to install libreadline.so.7


I'm trying to set up the environment of deepmind/dqn, https://github.com/deepmind/dqn, I run ./install_dependencies.sh to install
  • LuaJIT and Torch 7.0
  • nngraph
  • Xitari
  • AleWrap

first.But I got:

/home/dqn/torch/bin/luajit: error while loading shared libraries: libreadline.so.7: cannot open shared object file: No such file or directory

=> Torch7 has been installed successfully

Installing nngraph ...
/home/dqn/torch/bin/luajit: error while loading shared libraries: libreadline.so.7: cannot open shared object file: No such file or directory
Error. Exiting.

The install_dependencies.sh is:

# Install dependencies for Torch:
sudo apt-get update
sudo apt-get install -qqy build-essential
sudo apt-get install -qqy gcc g++
sudo apt-get install -qqy cmake
sudo apt-get install -qqy curl
sudo apt-get install -qqy libreadline-dev
sudo apt-get install -qqy git-core
sudo apt-get install -qqy libjpeg-dev
sudo apt-get install -qqy libpng-dev
sudo apt-get install -qqy ncurses-dev
sudo apt-get install -qqy imagemagick
sudo apt-get install -qqy unzip
sudo apt-get update


echo "==> Torch7's dependencies have been installed"





# Build and install Torch7
cd /tmp
rm -rf luajit-rocks
git clone https://github.com/torch/luajit-rocks.git
cd luajit-rocks
mkdir -p build
cd build
git checkout master; git pull
rm -f CMakeCache.txt
cmake .. -DCMAKE_INSTALL_PREFIX=$PREFIX -DCMAKE_BUILD_TYPE=Release
RET=$?; if [ $RET -ne 0 ]; then echo "Error. Exiting."; exit $RET; fi
make
RET=$?; if [ $RET -ne 0 ]; then echo "Error. Exiting."; exit $RET; fi
make install
RET=$?; if [ $RET -ne 0 ]; then echo "Error. Exiting."; exit $RET; fi


path_to_nvcc=$(which nvcc)
if [ -x "$path_to_nvcc" ]
then
cutorch=ok
cunn=ok
fi

# Install base packages:
$PREFIX/bin/luarocks install cwrap
$PREFIX/bin/luarocks install paths
$PREFIX/bin/luarocks install torch
$PREFIX/bin/luarocks install nn

[ -n "$cutorch" ] && \

echo ""
echo "=> Torch7 has been installed successfully"
echo ""


echo "Installing nngraph ... "
$PREFIX/bin/luarocks install nngraph
RET=$?; if [ $RET -ne 0 ]; then echo "Error. Exiting."; exit $RET; fi
echo "nngraph installation completed"

echo "Installing Xitari ... "
cd /tmp
rm -rf xitari
git clone https://github.com/deepmind/xitari.git
cd xitari
$PREFIX/bin/luarocks make
RET=$?; if [ $RET -ne 0 ]; then echo "Error. Exiting."; exit $RET; fi
echo "Xitari installation completed"

echo "Installing Alewrap ... "
cd /tmp
rm -rf alewrap
git clone https://github.com/deepmind/alewrap.git
cd alewrap
$PREFIX/bin/luarocks make
RET=$?; if [ $RET -ne 0 ]; then echo "Error. Exiting."; exit $RET; fi
echo "Alewrap installation completed"

echo
echo "You can run experiments by executing: "
echo
echo " ./run_cpu game_name"
echo
echo " or "
echo
echo " ./run_gpu game_name"
echo
echo "For this you need to provide the rom files of the respective games (game_name.bin) in the roms/ directory"
echo


when I test the code ./run_gpu {game_name}, I got:

../torch/bin/luajit: error while loading shared libraries: libreadline.so.7: cannot open shared object file: No such file or directory

when I run ldconfig -p | grep readline

My version is below 6

libreadline.so.6 (libc6,x86-64) => /lib/x86_64-linux-gnu/libreadline.so.6
libreadline.so (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libreadline.so
libguilereadline-v-18.so.18 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libguilereadline-v-18.so.18
libguilereadline-v-18.so (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libguilereadline-v-18.so

but I cannot install libreadline7 by : sudo apt-get install libreadline7-dev

Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package libreadline7-dev

How could I tackle the installation of libreadline7??

Hi:

Are you running Ubuntu 18.04?

Try running:

Code:
sudo apt-get install libreadline-dev
IF that fails do a Ubuntu Package Search and manually install the pkg.
https://packages.ubuntu.com/search?k...s=libreadline7

Here's the binary pkg here but it's for Ubuntu 18.04:-
https://ubuntu.pkgs.org/18.04/ubuntu...amd64.deb.html

I'm running on Ubuntu 5.4.0-6ubuntu1~16.04.9, so if I run
Code:
sudo apt-get install libreadline-dev
the newest version is libreadline6, then how could I install libreadline7 manually? Thank you so much.

It doesn't look like libreadline7 is available for Ubuntu 16.04 Xenial--
The package that you can manually install is libreadline-dev_6.3-8 ubuntu2-amd64.deb on this page under "Downloadable Files"

https://launchpad.net/ubuntu/xenial/...v/6.3-8ubuntu2
