aws-sam-cli: Unable to debug golang function using dlv from AWS documentation (`GLIBC_2.32' not found)

This is now a much wider issue with most distributions moving to the newer 3.32 version of glibc. Confirmed on Fedora 35, Ubuntu 21.10 and latest Arch & Manjaro installs.

We really need Go apps to be built in containers that contain a compatible lambda glibc version. This issue is not limited to aws-sam-cli. Any Go binary built on one of these newer distribution builds using glibc 2.32 or later will fail to run on any docker image or linux distro that uses glibc 2.31 or earlier.

I am running into the same issue @ivan-pesenti is facing. Anyone get debugging working with vscode?

Hi all!
I was stuck at trying to debug locally an AWS lambda function with Go as runtime. Below are my machine details:

• OS: Ubuntu 21.10
• AWS Cli: aws-cli/2.4.21 Python/3.8.8 Linux/5.13.0-37-generic exe/x86_64.ubuntu.21 prompt/off
• SAM version: SAM CLI, version 1.43.0
• IDE: VSCode
• Golang version: go version go1.18 linux/amd64

Below are the repro steps (I apologize if I’m too verbose but I’d like to give you my precise setup):

1. mkdir myLambda
2. cd myLambda
3. sam init
4. Below are the choices in the prompt
   1. 1 - AWS Quick Start Template
   2. 1 - Hello World Example
   3. N
   4. 4 - go1.x
   5. 1 - Zip
   6. myLambda
5. cd myLambda
6. make
7. Put a breakpoint in main.go file into handler()
8. Hit “AWS: Add Debug Configuration” provided by CodeLens right above the signature of handler() func
9. Start the debugger

I got this error:

Other attempts

I tried with this Makefile:

.PHONY: build

build:
	sam build --use-container

Same error as above

CGO_ENABLED

I compiled the program with this statement

GOOS=linux GOARCH=amd64 CGO_ENABLED=0 go build

After that I replaced the one below “.aws-ssm” folder but same error got.

Anyone can spot me in the right direction? If any details are missing I’ll provide.

Thanks!
