Rust - Production Adventure

Glibc and Musl..

Hi everyone,

I'm developing a project for a while with Rust for a special company. When i finished the project, i prepared the server to deploy app.

I have compiled the project on Windows for Linux. ( i know it's wrong, but i tried :) ) I encountered many problems while compiling Rust for Linux on Windows.

First:
I compiled with basic target parameter.

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

I got this error

 = note: the `x86_64-unknown-linux-gnu` target may not be installed

OK :(

I installed target with rustup

rustup target add x86_64-unknown-linux-gnu

Fine, continue..

We compile once more

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

aaanddd..

error: linker `cc` not found

😥

loading headcache..

Without trying more on Windows, i installed Ubuntu Subsystem for Windows.

I found my project by accessing the main folder on subsystem; like this

cd /mnt/c/Users/#user_name#/Desktop/Project

We compile one more time

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

oohh, come on. where is the error ?

ok calm, it's here

version `GLIBC_2.18' not found

GLIBC, the implementation of Standart C Library.

I researched for a long time for glibc problem.

I have worked with musl before. I installed musl without dealing with glibc. Musl, is a libc. An implementation of standart library.

What are the differences between glibc and musl?

glibc faster than musl but musl uses less space and it has been written in a more secure way and it has less security pitfalls.

ok, continue..

Install musl,

apt-get install musl-tools

change the target for musl

rustup target add x86_64-unknown-linux-musl

and compile

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

I finally compiled without any problems.
