When I build my rust project in macOS with apple sillicon using this command:
CARGO_HTTP_MULTIPLEXING=false cargo build
shows error like this:
= note: ld: library not found for -lpq
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I have tried to install
brew install libpq
brew link --force libpq
still did not fix this problem, what should I do to fix this problem? Is it the PostgreSQL lib did not support Apple Sillicon(Apple M1 Pro) right now? This is my project dependencies:
[package]
name = "reddwarf_dict"
version = "0.1.0"
edition = "2018"
# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html
[dependencies]
rocket = { version = "0.5.0-rc.1", features = ["json"] }
serde = { version = "1.0.64", features = ["derive"] }
serde_json = "1.0.64"
# database
diesel = { version = "1.4.7", features = ["postgres"] }
dotenv = "0.15.0"
chrono = "0.4"
log = "0.4"
env_logger = "0.9.0"
config = "0.11"
rust_wheel = "0.1.0"

I ran into this problem for this error message when running my cargo build:
= note: ld: library not found for -lpq
clang: error: linker command failed with exit code 1 (use -v to see invocation)
The way I solved it was by installing the required postgres C libraries using brew
brew install libpq
brew link --force libpq
Optionally if you are using fish
like I was I also added a link like this:
fish_add_path /opt/homebrew/opt/libpq/bin

I'm using Diesel ORM in my project here: https://github.com/EstebanBorai/estebanborai.com and this is how I set up the project to support Diesel.
libpq
using Homebrewbrew install libpq && brew link --force libpq
echo 'export PATH="/usr/local/opt/libpq/bin:$PATH"' >> ~/.zshrc
cargo install diesel_cli --no-default-features --features postgres
This is my Cargo.toml
file for reference on versions:
# -- snip --
[dependencies]
diesel = { version = "1.4.4", features = ["chrono", "postgres", "r2d2", "uuidv07"] }
r2d2 = "0.8.9"
# -- snip --
This is the output for my Diesel CLI version
< diesel --version
> diesel 1.4.1

It seems paths got moved in BigSur and/or Monterrey. I solved it by explicitly specifying the library path.
IE running rustc in the CLI:
rustc -L /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib ./main.rs
You can also specify it in the RUSTFLAGS env var, IE:
export RUSTFLAGS='-L /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib'
And then run:
rustc ./main.rs
or:
cargo build
In your example, you could do:
CARGO_HTTP_MULTIPLEXING=false RUSTFLAGS='-L /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib'
cargo build

Firstly, I run these commands:
brew install libpq
brew link --force libpq
Then:
PQ_LIB_DIR="$(brew --prefix libpq)/lib"
cargo install diesel_cli --no-default-features --features postgres
It works for me.
