AIX build not generating a jre image

Tue Oct 24 14:44:53 UTC 2017

  *   Do you get to this stage at all? I.e, can you see "Createing jre jimage" in the output?

Hi Magnus, when comparing the linux and aix logs  of our openjdk9 builds  ,   I see for Linux at some point :

gmake[3]: Entering directory ` . . . /nightly/jdk9/make'

/bin/echo Creating jre jimage

While on AIX it says :

make[3]: Entering directory ` . . . /nightly/jdk9/make'

make[3]: Nothing to be done for `jre'.

make[3]: Leaving directory ` . . . /nightly/jdk9/make'

this Looks wrong to me !

(  the   . . .   in the output has been removed by me it points to the build dir).

Best regards, Matthias

Hi Goetz,

How do our nightly builds look like? Do they create the JRE image?

Goetz is in a meeting.

None of our AIX builds creates a JRE image. Works on other platforms. Looks
like a bug.

I tried to build jre explicitly (make jre-image); build finishes
sucessfully but still no jre.
Since I don't have access to any AIX machines, it's difficult to for me to do much about this. Let me know if you need assistance in tracking this down.

Some suggestions:
run "make LOG=info,cmdlines" to track the progress of the build.

If you get lost in the log files, try running "make jre-image" and then "rm build/$BUILD/images/jre", and then "make LOG=info,cmdlines jre-image" to see only the output for the jre-image target.

Thanks for the hints! I'll try that. I played around last week with make -d --print-data-base but got lost in the information.

Last week I burned some time on this problem without much success. I got stuck understanding the rule in Images.gmk:

$(JRE_IMAGE_DIR)/$(JIMAGE_TARGET_FILE): $(JMODS) \
    $(call DependOnVariable, JRE_MODULES_LIST) $(BASE_RELEASE_FILE)
$(ECHO) Creating jre jimage
$(RM) -r $(JRE_IMAGE_DIR)
   $(JLINK_JRE_EXTRA_OPTS) \
$(JLINK_TOOL) --add-modules $(JRE_MODULES_LIST) \
   --output $(JRE_IMAGE_DIR)
$(TOUCH) $@

and its brethren.

It seems this rule just does not get executed for jre-image. So, trying to understand this (I am no makefile expert):

$(JRE_IMAGE_DIR)/$(JIMAGE_TARGET_FILE) is one file from the target dir, in this case jre/java, whose non-existence or out-of-dateness triggers the rule

Dependencies:
 - $(JMODS) is <outputdir>/jmods, which gets built and does exist
 - $(call DependOnVariable, JRE_MODULES_LIST)
This is just a macro that creates a dependency on the contents of the variable JRE_MODULES_LIST.

$(BASE_RELEASE_FILE) is a text file which, if it exists and it contains the value of $JRE_MODULES_LIST, will result false (not out of date), otherwise it will update the file with the value of $JRE_MODULES_LIST and return true, triggering the target, yes? If I got this right, why do we use the same output file for all targets (jre, jdk) etc?
No, this is a separate dependency. It's the file named "release" in the image that is to be included. If it has changed we need to trigger a new image.

Do you get to this stage at all? I.e, can you see "Createing jre jimage" in the output? If not, there's a problem before we even get to this rule. Otherwise, the jlink command is likely broken. Try copy-pasting the full jlink command and running it from the shell directly to see what happens.

I created https://bugs.openjdk.java.net/browse/JDK-8189618 to track this.

Hi Steve,

I think this is an error.
We never decided not to generate a jre image as far as I know.

Best regards,
   Goetz.

Subject: AIX build not generating a jre image

Hi all,

When building OpenJDK9 on AIX should the build generate a JRE image ie
build/aix-ppc64-normal-server-release/images/jre/bin as well as a JDK
image
ie build/aix-ppc64-normal-server-release/images/jdk/bin?  When I try
building on my AIX system it is only generating a JDK image. Is this a
issue or is
it working correctly?

Thanks
