Hi Doug,
HOTSPOT_VERSION_STRING comes from VERSION_STRING:
hotspot/make/lib/CompileJvm.gmk:
-DHOTSPOT_VERSION_STRING='"$(VERSION_STRING)"
and VERSION_STRING comes from configure. In your build directory you can do:
grep VERSION_STRING spec.gmk
VERSION_STRING := 9-internal+0-2016-06-29-155201.d046063.jdk9-hs-comp
-DVERSION_STRING='"$(VERSION_STRING)"' \
You can influence this version number with various configure options:
configure --help | grep "with-version"
--with-version-string Set version string [calculated]
--with-version-pre Set the base part of the version 'PRE' field
--with-version-opt Set version 'OPT' field (build metadata)
--with-version-build Set version 'BUILD' field (build number) [not
--with-version-major Set version 'MAJOR' field (first number) [current
--with-version-minor Set version 'MINOR' field (second number) [current
--with-version-security Set version 'SECURITY' field (third number) [current
--with-version-patch Set version 'PATCH' field (fourth number) [not
Regards,
Volker
PS: the correct list for build related questions is build-dev.
build-infra-dev was for the development of the new build system.
