Installing Convlab on Centos7

If you are using Convlab on Centos7, here are some notes.

Install development tools

sudo yum groupinstall 'Development Tools'

Libraries not installed

If you receive something like:

ImportError: /lib64/libstdc++.so.6: version `CXXABI_1.3.8' not found 

Good article installing new gcc. I chose version 8.3.0.

curl https://ftp.gnu.org/gnu/gcc/gcc-8.3.0/gcc-8.3.0.tar.gz -O
tar xvzf  gcc-8.3.0.tar.gz

Install dependencies

sudo yum install gmp-devel mpfr-devel libmpc-devel -y

Configuration and installation

mkdir gcc-8.3.0-build
cd gcc-8.3.0-build
../gcc-8.3.0/configure --enable-languages=c,c++ --disable-multilib
make -j$(nproc) && sudo make install

Post install Update /etc/profile.

export PATH=/usr/local/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/lib:/usr/lib:/usr/local/lib64:/usr/lib64
