Build error on jdk8/tl project - Thread.o:(.data.rel+0xbc): undefined reference to JVM_SetNativeThreadName

[Martijn Verburg]

Hi Andrew/Alan,

Thanks for responding! I suspect you are right, I'm only building the tl
project, which i guess is a partial build? I saw the patch that Andrew
mentioned but hadn't put 2 and 2 together that I'd need to build the
hotspot part separately first.

I'll try that next, my next post will likely be a q about building the
hotspot part or providing the extra info Andrew requested.

Cheers,
Martijn

we think we've tracked it down to the fact that the reference to
JVM_SetNativeThreadName is not in java_lang_Thread.h (a generated header).
 Looking at java_lang_Thread.h, the reference that is the closest is
Java_SetNativeThreadName, which we think has been incorrectly generated.

failure if doing a partial build and the import JDK is not in sync.
