How to resolve linker error in RUST Cross compilation

I am trying to achieve cross compilation in rust to the raspberry pi. However there was a linkage error while compiler:

error: linking with `cc` failed: exit status: 1

However for resolving that I have to download new linker and not use the default. While doing so I checked the information of my raspberry system by using:

rustup show

Got the following result:

Default host: x86_64-unknown-linux-gnu
rustup home:  /home/akumar/.rustup

installed targets for active toolchain
--------------------------------------

arm-unknown-linux-gnueabihf
armv7-unknown-linux-gnueabihf
x86_64-unknown-linux-gnu

active toolchain
----------------

stable-x86_64-unknown-linux-gnu (default)
rustc 1.64.0 (a55dd71d5 2022-09-19)

Now for resolving the issue I have to download the package using the following command:

sudo apt install gcc-armv7-unknown-linux-gnueabihf

but after running the command, I am getting the following error:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package gcc-armv7-unknown-linux-gnueabihf

Please try this: sudo apt install gcc-arm-linux-gnueabihf for build your rust project: cargo build --target=armv7-unknown-linux-gnueabihf

Please check tool - cross: https://github.com/cross-rs/cross Cross uses docker for build and makes libraries isolation.
