Dear All,
I am testing cross compile OpenJDK-9+158 for our embedded system using
buildroot, I can build server and client variants successfully, but the
output compact1 profile file size is too big, then I tried to build
minimal
variant, failed when linking libjvm.so.
I checked build/linux-arm-normal-minimal-release/hotspot/variant-minimal/
libjvm/objs/_BUILD_LIBJVM_objectfilenames.txt, jvmtiEnvBase.o
and jvmtiEnvThreadState.o are not listed in the file (which is required
from the error message below).
Right - JVM TI is not part of the Minimal VM. At the moment it looks
like some service has either been enabled when it should not have been,
or has not been correctly if'def in the source.
As far as I can see your error messages are complaining about missing
functions that are called from the same sources as the functions that
are missing! ie.
undefined reference to
`JvmtiEnvBase::get_current_contended_monitor(JavaThread*, JavaThread*,
_jobject**)'
/tmp/cc27HS5M.ltrans0.ltrans.o: In function `VM_GetOwnedMonitorInfo::doit()
but VM_GetOwnedMonitorInfo is defined in jvmtiEnv.cpp which should be
included or excluded the same as jvmtiEnBase.cpp. Here's the logic in
the makefile that controls this:
ifneq ($(call check-jvm-feature, jvmti), true)
JVM_CFLAGS_FEATURES += -DINCLUDE_JVMTI=0
JVM_EXCLUDE_FILES += jvmtiGetLoadedClasses.cpp jvmtiThreadState.cpp
jvmtiExtensions.cpp \
jvmtiImpl.cpp jvmtiManageCapabilities.cpp jvmtiRawMonitor.cpp
jvmtiUtil.cpp jvmtiTrace.cpp \
jvmtiCodeBlobEvents.cpp jvmtiEnv.cpp jvmtiRedefineClasses.cpp
jvmtiEnvBase.cpp jvmtiEnvThreadState.cpp \
jvmtiTagMap.cpp jvmtiEventController.cpp evmCompat.cpp
jvmtiEnter.xsl jvmtiExport.cpp \
jvmtiClassFileReconstituter.cpp
endif
Can you run with LOG=trace so that each compiled file is listed in the
build log, then see if there are any jvmti* files listed there.
Thanks,
David
Can you provide the lines from your spec.gmk that define the
JVM_FEATURES_* variables please.
Thanks,
David
