Rust Diesel failing to compile with linker error

I was using Diesel and it was working with the following Cargo.toml config:

diesel = { version = "1.4.4", features = ["postgres"] }

Running without Diesel and everything is fine. When I introduce the above dependency it fails to compile with the following error:

clang: error: linker command failed with exit code 1 (use -v to see invocation)

OS: MacOS Big Sur

Update I've installed libpq with the following command:

brew install libpq

I then tried to link it with the following command:

brew link --force libpq

This worked. Thanks for the comments that pointed me into this direction.

Solution

  • You need to have postgres installed correctly on your system:

    // ubuntu
$ sudo apt install libpq-dev

// osx
$ brew install libpq
