Buidling

Prerequisites

The following dependencies must be installed on your host machine to build the project:

• rustc
• cargo
• rustup

Building for a Specific Target Platform

The project is currently configured to target 4 platforms, namely linux x86_64, windows x86_64, macOS x86_64, and macOS Apple Silicon (See: Cargo.toml).

Before building binaries for any of the mentioned platforms, it is necessary to install the corresponding platform toolchains. You can install these toolchains by utilizing the provided utility script: install_targets.sh.

Example of a build command for a binary targeting the linux x86_64 platform:

cargo build --release --target x86_64-unknown-linux-gnu

The resulting binary file will be stored under the target/release directory.

Usage

The usage is quite straightforward. Once you have the tool binary (whether by building it yourself or by downloading a release variant), refer to the embedded manual.

To bring up the embedded manual use the following command:

cryptic --help
