Hello , while adjusting the jspawnhelper build settings with 8174086,
it has been noticed that the jexec build settings need some
simplification as well.
The bug
https://bugs.openjdk.java.net/browse/JDK-8174242
has been created for this.
When looking into it, I had some questions :
http://hg.openjdk.java.net/jdk10/jdk10/jdk/file/ae7afa9abe67/make/launcher/Launcher-java.base.gmk
The makefile (make/launcher/Launcher-java.base.gmk ) handles Solaris
32bit, but is this really supported in jdk 9 or 10 ( I think it
was removed in 9 and only 64bit Solaris support remains ) ?
We do not support 32bit Solaris. The issue with jexec for Solaris was
raised a while back and the conclusion was to scrap support, so no need
to build it for Solaris at all.
ifeq ($(OPENJDK_TARGET_OS), solaris)
ifeq ($(OPENJDK_TARGET_CPU_BITS), 32)
BUILD_JEXEC := 1
endif
endif
ifeq ($(OPENJDK_TARGET_OS), linux)
BUILD_JEXEC := 1
endif # OPENJDK_TARGET_OS
#
# jdk/make/java/jexec/Makefile
#
ifeq ($(BUILD_JEXEC), 1)
Then there is handling for macosx left , but the build is not enabled
for macosx, does it still make sense to include the macosx handling
(there is even a separate jexec.c for macosx) :
This is indeed weird. I don't think we ever built jexec for macosx so
the source file should likely be removed. That is however a question for
core-libs I think.
The makefile logic shouldn't need to be that specific though. Our modern
pattern for this is something like this:
SRC := $(call uniq, $(wildcard \
$(JDK_TOPDIR)/src/$(MODULE)/$(OPENJDK_TARGET_OS)/native/launcher \
$(JDK_TOPDIR)/src/$(MODULE)/$(OPENJDK_TARGET_OS_TYPE)/native/launcher \
$(JDK_TOPDIR)/src/$(MODULE)/share/native/launcher))
This will automatically look in all the directories where source files
are supposed to be and pick the most specific one if there are any with
the same name. Since the share launcher dir contains more src files, you
will need to leave the INCLUDE_FILES := jexec.c this time.
For libraries, we have abstracted this construct in the macro
FindSrcDirForLib (LibCommon.gmk) but we haven't done the same for
launchers yet.
/Erik
ifeq ($(OPENJDK_TARGET_OS), windows)
else ifeq ($(OPENJDK_TARGET_OS), macosx)
BUILD_JEXEC_SRC := $(JDK_TOPDIR)/src/java.base/macosx/native/launcher
else
BUILD_JEXEC_SRC := $(JDK_TOPDIR)/src/java.base/unix/native/launcher
endif
Should I remove the solaris 32bit / macosx handling for jexec from
make/launcher/Launcher-java.base.gmk ?
