ARM release has a dependency on glibc 2.27 (doesn't work with Ubuntu 16 or Debian 9)

I tried out the insiders build. It is crashing and I see these errors:

/home/byu/.vscode-server/extensions/ms-vscode.cpptools-0.30.0-insiders/bin/cpptools: /lib/arm-linux-gnueabihf/libm.so.6: version `GLIBC_2.27' not found (required by /home/byu/.vscode-server/extensions/ms-vscode.cpptools-0.30.0-insiders/bin/cpptools)
/home/byu/.vscode-server/extensions/ms-vscode.cpptools-0.30.0-insiders/bin/cpptools: /lib/arm-linux-gnueabihf/libc.so.6: version `GLIBC_2.28' not found (required by /home/byu/.vscode-server/extensions/ms-vscode.cpptools-0.30.0-insiders/bin/cpptools)

My arm system is running Ubuntu 16.04. I believe (could be wrong) this is limited to libc-2.23. Any suggestions? Will this be limited to newer libc versions?

@jgoeders Thanks for letting us know. I'll look into it.

We built our binary using Debian Buster, which uses glibc 2.28, so Ubuntu 20 would work, but Ubuntu 16 and 18 won't.

I see Ubuntu 18 ARM builds available, which have a glibc 2.27 dependency that we could possibly build against, but I don't see an Ubuntu 16 ARM build -- how did you get Ubuntu 16 for ARM?

For context, the board I am using is a Xilinx PYNQ board (so not a raspberry PI board like most people)

I believe the Linux image was built using the files available at http://ports.ubuntu.com/ubuntu-ports/dists/bionic/ which seem to have armhf file.

As of now, it's looking like we probably won't support Ubuntu 16 for ARM/aarch64 due to low usage (or this issue gets more upvotes). But we plan to support Ubuntu 18 (possibly with 0.30.0-insiders4 if 0.30.0-insiders2/3 don't work).

OK, Ubuntu 18 sounds reasonable. Thanks for the quick followup.

I wanted to confirm that with 0.30.0-insiders2 the intellisense doesn't work with Ubuntu 16 on ARM (odroid xu4). Debugging does work. Thanks for the development!
