Build failures after 8214976

[Doerr, Martin]

Hi Julian,

I have already filed an issue related to that change:
https://bugs.openjdk.org/browse/JDK-8288101

Does the build work when using configure flag --disable-warnings-as-errors ?
Or is it an additional problem?
Which compiler version are you using?

Best regards,
Martin

Betreff: Build failures after 8214976

After 8214976 builds on my local device seem to be failing when the
precompiled headers are being generated, and I'm somewhat stumped by what
seems to be causing them. Has anyone else faced this issue besides me? The
failure log is below, in case that helps
