Need help replicating the official build

[leocb]

Hi, Due to my company's Safety & Distribution policies, I cannot simply use the pre-compiled runtimes from Microsoft, I have to compile my own version. So I'm looking for how I can replicate the official linux build; my goal is to have a redistributable package that is equivalent to what I'd download from Microsoft website.

I followed the docs on how to build the runtime, with some changes because I'm on Oracle Linux 9 (UEK, RHEL compatible), these are the steps:

dotnet runtime build instructions for Oracle Linux 9 (click to expand)

Clone .NET runtime Git repo

cd ~/git
git clone --recursive https://github.com/dotnet/runtime.git
cd runtime
git checkout v6.0.14

Build requirements for .NET Runtime

# Install the dependencies
sudo yum install -y cmake llvm lld clang gcc gcc-c++ make python3 curl lldb libicu-devel openssl-devel numactl-devel zlib-devel krb5-devel lttng-ust
sudo dnf --enablerepo=ol9_codeready_builder install lttng-ust-devel

Build .NET Runtime

# Enables SHA1 on the OpenSSL library, building without this flag fails (!)
export OPENSSL_ENABLE_SHA1_SIGNATURES=1
# Build the runtime:
./build.sh -c release -lc release -rc release -a x64 -os linux -s clr+libs -v n

This builds successfully without any errors or warnings. Then I copy the contents from /artifacts/bin/testhost/net6.0-Linux-Release-x64/dotnet because that's the only folder that has the same structure as the pre-compiled download. However, when I try to run it later inside a docker container, my version throws an error that it could not find libc.dll, while the version from microsoft does not throw this error.

Also the file versions are all 42.42.42424 - which points to me that I'm missing some steps or parameters for the "correct" output.

bottom line is: how do I compile the runtime to be the same-ish as microsoft's redistributable?

Thanks!

You can look for instructions at https://github.com/dotnet/source-build, which is used for certain Linux distros like Ubuntu and RHEL to build dotnet from source.

I didn't know about the existence of that repo, thank you, I'll take a look at it, seems like it solves a lot of issues I'm having. If I need anything else I'll reopen this issue
