address-book-with-redux-tui

This is a CLI app that implements an immutable data structure that represents an address book. It also has a rich text user interface. Mutations to this address book must happen via a Redux store, and actions that are dispatched to it. Along w/ a reducer function.

This app is meant to be a pedagogical example of how to use the r3bl_rs_utils crate quite comprehensively.

  • Change the simple terminal UI to use r3bl_rs_utils tui module.
  • You can find all the TODOs here, and work completed here.

Issues w/ loading shared libraries libssl.so.1.1 when running cargo run on Ubuntu 22.04

With Ubuntu / PopOS! 22.04 libssl v3 is installed by default. And the APT sources list for v1.1 is removed. There are lots of libraries written in Rust that have dependencies on locally installed libssl.so.1.1 file.

Problem w/ OpenSSL v1.1

Where is the libssl.so.1.1 file? You can search for this file using this command (make sure you have fd installed via brew):

fd -t f libssl.so.1.1 /usr/

Here is a list of errors that we get:

  1. In our case, running cargo run results in an error message like: error while loading shared libraries libssl.so.1.1.
  2. Passing --features vendored-openssl to cargo build doesn't do anything (the libssl.so.1.1 requirement must be in one of the underlying dependencies).

For some crates, eg: cargo-outdated, you can force them to build openssl 1.1 from source rather than using the system installed version. Here's the command to do this (--features vendored-openssl):

cargo install --locked cargo-outdated --force --features vendored-openssl

Solution - install them manually

Download old versions of both libssl and libssl-dev from archive repository. Here's a so thread which points to the archive repository.

  1. Download & install the libssl???.deb file first:

    cd ~/Downloads/
wget https://snapshot.debian.org/archive/debian-security/20220626T182543Z/pool/updates/main/o/openssl/libssl1.1_1.1.1n-0%2Bdeb11u3_amd64.deb
sudo dpkg -i libssl1.1_1.1.1n-0+deb11u3_amd64.deb

  2. Download & install the libssl-dev???.deb file last:

    cd ~/Downloads/
wget https://snapshot.debian.org/archive/debian-security/20220626T182543Z/pool/updates/main/o/openssl/libssl-dev_1.1.1n-0%2Bdeb11u3_amd64.deb
sudo dpkg -i libssl-dev_1.1.1n-0+deb11u3_amd64.deb

That's it. If you run the following commands you will see that libssl.so.1.1 has been installed to /usr/lib/??? & cargo run works.

fd -t f libssl.so.1.1 /usr/
/usr/lib/x86_64-linux-gnu/libssl.so.1.1
