Setting/overriding HOTSPOT_VERSION_STRING

[Volker Simonis]

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.
