Buildpack fails when packaged with go 1.20

[amhuber]

What version of the buildpack you are using?
v1.1.3

If you were attempting to accomplish a task, what was it you were attempting to do?

1. Package the offline buildpack on a system using go 1.20.3
2. Upload the new buildpack to CF
3. Push the binary test app from cf-acceptance-tests

What did you expect to happen?
Staging should succeed

What was the actual behavior?
The buildpack threw the following errors:

[STG/0] ERR /tmp/buildpacks/7d3e828e705dfe804f399b84000a6813/bin/supply: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.32' not found (required by /tmp/buildpacks/7d3e828e705dfe804f399b84000a6813/bin/supply)

This appears to be related to a change in go 1.20 with linking to system libraries, see cloudfoundry/smb-volume-release@bf037f3.

Please confirm where necessary:

• I have included a log output

I suppose you used the old cflinuxfs3 stack, cflinuxfs4 has a newer glibc version since it is based on ubuntu 22.04

This issue is stale, it didn't have anything to do with the cflinuxfs version but was due to a change in Go. It was fixed in 76b85ae so I'll close this.
