Make download binaries work on a broader set of Linux distros

[tmds]

The distro that is used to build the release binaries limits on what distros these binaries can be used. Using an older distro enables the binaries to work across a broader set of distros.

To make their .NET linux-x64 binaries work across a large of distros, Microsoft pick an 'old' distro for each release. Up until .NET 6, CentOS 7 was used, .NET 8 uses Ubuntu 16.04, and .NET 9 will use Ubuntu 18.04.

It would be nice if netcoredbg release binaries work on a large set of the Microsoft supported distros.

To try some old distro builds, I compiled netcoredbg with the Ubuntu versions Microsoft is using. The build failed with a c++ error on Ubuntu 16.04. On Ubuntu 18.04, it passed without errors. The Ubuntu 18.04 works across more distros than the currently provided release downloads, including Ubuntu 18.04, RHEL 8, and Debian Buster.

The build failed with a c++ error on Ubuntu 16.04

Can you share build error and build command?

Thanks for feedback, we'll consider switch to older ubuntu. For now you can use build from source on ubuntu 18.04.

Can you share build error and build command?

In the ubuntu:16.04 container image I ran these commands:

apt-get update
apt-get install git curl cmake clang
cd
git clone https://github.com/Samsung/netcoredbg
cd netcoredbg/
mkdir build
cd build
CC=clang CXX=clang++ cmake ..
make

The compilation fails with:
