Failed to find OpenSSL development headers.

You can try fixing this setting the OPENSSL_DIR environment variable pointing to your OpenSSL installation or installing OpenSSL headers package specific to your distribution:

  # On Ubuntu
  sudo apt-get install libssl-dev
  # On Arch Linux
  sudo pacman -S openssl
  # On Fedora
  sudo dnf install openssl-devel

I could easily fix it with adding 'openssl = { version = "0.10", features = ["vendored"] }' in Cargo.toml in [dependencies] target.

Can confirm this fix also works on Linux Mint 21.3 (virginia) , it builds the source successfully.

Can confirm this works on debian 12/bookworm:

1. install libssl-dev with apt-install libssl-dev
2. modify Cargo.toml by adding openssl = { version = "0.10", features = ["vendored"] } under [dependencies] section
3. set OPENSSL_DIR env variable to /usr/lib/x86_64-linux-gnu
4. finally run cargo build --release
