[SOLVED] java-config (Broken with strange behaviour)

Message

Thistled · Post by **Thistled** » Wed Sep 04, 2013 6:59 pm

Apologies guys if this is in the wrong section.
Having a big problem today when updating my system.

Packages ant-core and ant-nodeps fails with a strange message about being unable to find a system VM.
I went to the Gentoo documentation and looked at the java upgrade guide.
It says to set the system vm I....

Code: Select all

java-config --list-available-vms

instead of what is expected [per the documentation] I get...

Code: Select all

~ # java-config --list-available-vms
usage: java-config-2 [options] requirement_or_url ...
   or: java-config-2 --help

error: option --list-available-vms not recognized

This is freaking me out, as it is just an update and things go bad. (All the flippin time)

Looks like packages which use JRE's or JDK's are going to run into trouble because my system can't find a VM.
I don't know why my system wants JDK's because I sure as hell don't develop.
emerge --info for ant-core

Code: Select all

My system is a mixture of ~ and stable.
Over the last year or so I have been gradually dealing with pulling back some packages to stable - when possible.
Could this problem have anything to do with that.
I don't understand why the instructions in the documentation are falling over.
Any help would be appreciated.

Peace.

** UPDATE **

If I try to build any package which requires a VM then it borks straight away.

DONAHUE · Post by **DONAHUE** » Fri Sep 06, 2013 6:45 pm

Code: Select all

emerge -s java-config

both 2.1.12-r1(newest stable) and 2.2.0 (testing) respond correctly to java-config --list-available-vms and java-config-2 --list-available-vms for me.
Have you run

Code: Select all

java-config-2  --list-available-vms

as the message suggests?
Does

Code: Select all

etc-update

suggest updating any java files?

emerge java-config produces directory /etc/java-config-2. In /etc/java-config-2 is a symlink /etc/java-config-2/current-system-vm which points to a directory containing the selected virtual machine executables; in my case: /usr/lib/jvm/oracle-jdk-bin-1.7 . You may be missing lines somewhwere that say java-config = java-config-2.

error: can't create or remove files in install directory

The following error occurred while trying to add or remove files in the
installation directory:

    [Errno 13] Permission denied: '/usr/lib/python2.7/site-packages/test-easy-install-11156.write-test'

The installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

    /usr/lib/python2.7/site-packages/

Perhaps your account does not have write access to this directory?  If the
installation directory is a system-owned directory, you may need to sign in
as the administrator or "root" account.  If you do not have administrative
access to this machine, you may wish to choose a different installation
directory, preferably one that is listed in your PYTHONPATH environment
variable.

For information on other options, you may wish to consult the
documentation at:

  http://packages.python.org/distribute/easy_install.html

Please make the appropriate changes for your system and try again.

what is your java-config version? have you run

Code: Select all

emerge java-config

today? I would.
what does etc-update produce?

in my case /usr/lib/jvm/oracle-jdk-bin-1.7 is in turn a symlink to /opt/oracle-jdk-bin-1.7.0.25. so my actual executable is in the same place as (presumably) your oracle-jdk-bin-1.7.0.25 is.

The exterior is totally broke; but why and how, to know that you'll need to look at what happened to the interior. Take a look at `cat $(command -v java-config)` and see if it implements Java related functionality or not; from what I see in this forum thread, I guess not because it likely has been overwritten.

Without knowing the state of that file, a Google for "usage error option not recognized" brings us at http://docs.python.org/2/library/getopt.html which is Python; that's particularly interesting because the wrapper is actually supposed to be a shell script, as it has been for some time. Or maybe the wrapper works, and one of the files that gets wrapped is tampered with; but you can trust me on this, we don't use getopt there. Which becomes clear from simply doing a `java-config --test` that shows totally different error output.

We've had this happen before somewhere, but we couldn't pinpoint why this happens; so, if you know what you recently did related to this that would help, otherwise this is yet another unsolvable case where we can't identify the reason. Anyhow, given that java-config is tampered, you will likely just want to emerge java-config again; if emerging it again still makes things broken, then there is something odd going on with your mix of stable and unstable, but I am not sure what exactly...

Or maybe the wrapper works, and one of the files that gets wrapped is tampered with; but you can trust me on this, we don't use getopt there. Which becomes clear from simply doing a `java-config --test` that shows totally different error output.

Anyhow, given that java-config is tampered, you will likely just want to emerge java-config again; if emerging it again still makes things broken, then there is something odd going on with your mix of stable and unstable, but I am not sure what exactly...

I can't emerge xjavac and the other packages which need to be built along with it because the ebuilds fail, as they can't determine a VM.
Stuck in a rather vicious circle.

I am intrigued and confused by..

Are these what are known as environment variables? If so, how do I check if they are set properly, and where to set if not?

The wrapper itself is apparently fine; so, yes, one of the java config files is not what it is supposed to be. You cannot use, check or emerge Java things until you fix up java-config.

Thanks for the quick response TomWij.

Okay, I will now follow Donahues advice and remove what he suggests and start again.
Will update shortly.

After emerging java-config and java-config-wrapper I am left with the same.
That is, whenever I run java-config it behaves the opposite to what the documentation says.

Code: Select all

# java-config-2 --list-available-vms
usage: java-config-2 [options] requirement_or_url ...
   or: java-config-2 --help

error: option --list-available-vms not recognized

But when I try it without -- I get...

Code: Select all

# java-config-2 list-available-vms
Searching for list-available-vms
Reading http://pypi.python.org/simple/list-available-vms/
Couldn't find index page for 'list-available-vms' (maybe misspelled?)
Scanning index of all packages (this may take a while)
Reading http://pypi.python.org/simple/
No local packages or download links found for list-available-vms
error: Could not find suitable distribution for Requirement.parse('list-available-vms')

This type of error is what I am seeing when other packages are failing.
Just like when I try to build gcr, I get...

Code: Select all

usage: gdbus-codegen [options] requirement_or_url ... 
    or: gdbus-codegen --help 

 error: option --interface-prefix not recognized 
 make[2]: *** [gcr-dbus-generated.c] Error 1

Is this because I am having trouble with the VM?

This has nothing to do with Java anymore as far as I know, I'll ping the Python guys for an explanation and / or solution.

Many thanks TomWij.
Because I am not the most intelligent Gentoo user, I'm never to sure which tree I should be barking up.

Python guy here

You have overwritten your copy of /usr/bin/python-exec with easy_install. It's an easy mistake to make if you don't have the latest version of dev-python/setuptools installed.

https://bugs.gentoo.org/show_bug.cgi?id=468378

To fix it, re-install dev-python/python-exec.

Thistled · Post by **Thistled** » Sat Sep 07, 2013 3:57 pm

Hey floppymaster, great to hear from you.
I am not even sure why my python-exec would be overwritten.
I think I did see some sort of reference to Easy Install when running java-config without the -- .
I have just re-emerged python-exec-0.3.1
When you say the latest python/setuptools, do you mean the latest stable or ~ ?
I have ~setuptools-1.0 installed
Now that python-exec is rebuilt, do I need to do anything like python-updater?

Thanks in anticipation man!

Post by **floppymaster** » Sat Sep 07, 2013 4:07 pm

python-exec usually gets overwritten when a user tries to install some python software without using portage (via easy_install or pip). It's a bit difficult to figure out unless you catch it immediately.

We fixed setuptools to resolve this problem in setuptools-0.9.8-r1, so setuptools-1.0 should be fixed as well. It is possible that you have found another way to trigger the same problem.

You don't really need to run anything like python-updater. If you want to be extra paranoid, you could reinstall all python packages by running the following command:

emerge /usr/lib/python2.7/site-pacakges
