Thanks for the reply Erik.

running with --disable-warnings-as-errors helped.

I also ran make dist-clean before building again.

The build failed at a later stage now.



Here is the new output:

Apparently clang believe this is an error, and not just a warning, so 
this is a source code issue, and not a build issue per se.

If this only happens in panama, you need to raise it with the Panama 
developers (cc:ed). If you can also reproduce it on the main jdk/jdk 
repo, then you can discuss it on hotspot-...@oopenjdk.java.net.

Hello Sebastian,

Please try running configure with --disable-warnings-as-errors.

When using compiler versions (or OS versions) other than the ones listed
in doc/building.md it's common to have warnings triggered and we run
with warnings treated as errors by default.

I have attached the full log output from running make. I have read the
building.html and troubleshooting section and did not find anything
relevant to this error:

Any help would be appreciated.
