Cannot cross compile to Linux ARM64 on Linux x86_64

[stormshield-guillaumed]

Describe the bug

I get a compilation error when trying to build for Linux ARM64 on the linux-build-xcomp:22.04 docker image while building for Linux x86_64 works. I'm trying to build the secnetperf executable for both architecture.

Affected OS

• [ ] Windows
• [X] Linux
• [ ] macOS
• [ ] Other (specify below)

Additional OS information

Linux Ubuntu 22.04.3 LTS 5.15.0-91-generic x86_64 Docker version 24.0.7, build afdd53b

MsQuic version

main

Steps taken to reproduce bug

1. Run the following commands on a Linux machine with docker installed :

docker pull ghcr.io/microsoft/msquic/linux-build-xcomp:22.04
docker run -it --rm --volume "$(pwd)/bin:/work/bin" ghcr.io/microsoft/msquic/linux-build-xcomp:22.04 bash

2. Run the following commands inside the docker container :

cd work
git clone https://github.com/microsoft/msquic.git
cd msquic
pwsh

3. Run the following commands inside the powershell :

./scripts/prepare-machine.ps1 -ForContainerBuild
./scripts/build.ps1 -Config Release -Arch arm64 -Platform linux -DisableTools -DisableTest -Clean

4. See the following error (truncated for brevity) :

Expected behavior

The build for Linux ARM64 on the linux-build-xcomp:22.04 docker image should succeed.

Actual outcome

The build fail saying the ARM architecture is unsupported.
