[SOLVED] System not finding libjava.so

f000l · 10-29-2009, 05:32 AM

Hello

I'm using slackware13 (32bit), and just installed the jre package to be able to use java programs, but when i try to execute the java command, it complains about not finding libjava.so

Code:

Error: could not find libjava.so
Error: could not find Java 2 Runtime Environment.

libjava is located at

Code:

/usr/lib/java/lib/i386/libjava.so

And i've added the dir to ld.so.conf

I've tried symlinking the lib to /usr/lib but that doesn't work. I tried installing on another slack13 comp and there's no problem there :/

I need some help getting java to find it's lib.

You probably still need to logout and login again to re-initialize your enviroment. Or run

Code:

 . /etc/profile

in a shell right before running "java" if a reboot is not convenient at the time.

Still can't find libjava, so I need to reboot? :/

EDIT: Rebooting now.

Ok, so reboot did'nt help :/

What happens if you define the full path to java while executing the program?
/usr/lib/java/bin/java program

echo $PATH
Make sure java is in your path.

Are you using ssh by any chance? As Slackware does not explicitly export the java home with ssh. Normal ssh clients do not have an issue with this. I use an ssh client that does, and had to recompile ssh and add the java home to the default path.

f000l · 10-29-2009, 06:52 AM

hmm. If i specify the whole path it works...

Code:

echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/games:/usr/lib/java/bin:.:/sbin:/usr/sbin

I am using SSH, yes. PuTTy from a machine running windows. I don't have to use the absolute path when i SSH to another local machine though.

Maybe check your environment like so:

Code:

env |grep -i java

You should find /usr/lib/java/bin {and / or} /usr/lib/java/jre/bin in your PATH and you should have JAVA_HOME in your environment as well. This is the output from the env-pipe-grep command from my laptop:

Code:

MANPATH=/usr/local/man:/usr/man:/usr/lib/java/man:/usr/lib/java/man:/usr/share/texmf/man
PATH=/usr/local/bin:/usr/bin:/bin:/usr/games:/home/konrad/bin:/opt/apache-ant/bin:/usr/lib/java/bin:/usr/lib/java/jre/bin:/usr/lib/qt/bin:/usr/share/texmf/bin
JAVA_HOME=/usr/lib/java

If not, you can add /usr/lib/java/bin (for the JDK) {and / or} /usr/lib/java/jre/bin (for the JRE) to the PATH varb in /etc/profile to set it up for all users:

Code:

PATH="$PATH:/usr/lib/java/bin:/usr/lib/java/jre/bin"
JAVA_HOME="/usr/lib/java"
export PATH JAVA_HOME

or add the same lines to ~/.profile to set it up for individual users.

HTH.

I have java in my path according to the env listing.

Code:

env |grep -i java
MANPATH=/usr/local/man:/usr/man:/usr/lib/java/man
PATH=/usr/local/bin:/usr/bin:/bin:/usr/games:/usr/lib/java/bin:.:/sbin:/usr/sbin:/usr/lib/java/bin:/usr/lib/java/jre/bin
JAVA_HOME=/usr/lib/java

Code:

PATH="$PATH:/usr/lib/java/bin:/usr/lib/java/jre/bin"
JAVA_HOME="/usr/lib/java"
export PATH JAVA_HOME

Did'nt work for me

Give this a try on the command line:

Code:

LD_LIBRARY_PATH=/usr/lib/java/lib/i386 program_name

Substitute "program_name" accordingly.

Shucks. One difference I have (looking back at your first post) is that I did not add java.so to /etc/ld.so.conf, so there are no libraries from my JAVA_HOME Tree:

As root:

Code:

[root@kjhlt4 ~]# ldconfig -p |grep -i java
        libqtjavasupport.so.1 (libc6) => /usr/lib/libqtjavasupport.so.1
        libqtjavasupport.so (libc6) => /usr/lib/libqtjavasupport.so
        libqtjava.so.1 (libc6) => /usr/lib/libqtjava.so.1
        libqtjava.so (libc6) => /usr/lib/libqtjava.so
        libkjava.so.1 (libc6) => /usr/lib/libkjava.so.1
        libkjava.so (libc6) => /usr/lib/libkjava.so
        libkdejava.so.1 (libc6) => /usr/lib/libkdejava.so.1
        libkdejava.so (libc6) => /usr/lib/libkdejava.so

As 'me':

Code:

[konrad@kjhlt4 TaxMap]$ /sbin/ldconfig -p |grep -i java
        libqtjavasupport.so.1 (libc6) => /usr/lib/libqtjavasupport.so.1
        libqtjavasupport.so (libc6) => /usr/lib/libqtjavasupport.so
        libqtjava.so.1 (libc6) => /usr/lib/libqtjava.so.1
        libqtjava.so (libc6) => /usr/lib/libqtjava.so
        libkjava.so.1 (libc6) => /usr/lib/libkjava.so.1
        libkjava.so (libc6) => /usr/lib/libkjava.so
        libkdejava.so.1 (libc6) => /usr/lib/libkdejava.so.1
        libkdejava.so (libc6) => /usr/lib/libkdejava.so

Maybe ?

As me:

Code:

$ ldconfig -p |grep -i java
        libbeecrypt_java.so.0 (libc6) => /usr/lib/libbeecrypt_java.so.0
        libbeecrypt_java.so (libc6) => /usr/lib/libbeecrypt_java.so

And as root:

Code:

# ldconfig -p |grep -i java
        libbeecrypt_java.so.0 (libc6) => /usr/lib/libbeecrypt_java.so.0
        libbeecrypt_java.so (libc6) => /usr/lib/libbeecrypt_java.so
# cat /etc/ld.so.conf
/usr/local/lib
/usr/i486-slackware-linux/lib
/usr/lib

Sorry about the ldconfig wild-goose-chase ...

I thought said that you had added /usr/lib/java/lib/i386 to /etc/ld.so.conf ...

I am stumped ... ??? ...

Are you running the jdk java or the jre java (or something else) ?

Code:

$ which -a java
/usr/lib/java/bin/java
/usr/lib/java/jre/bin/java

I have both installed so I see both ...

Code:

$ /usr/lib/java/bin/java -version
java version "1.6.0_16"
Java(TM) SE Runtime Environment (build 1.6.0_16-b01)
Java HotSpot(TM) Server VM (build 14.2-b01, mixed mode)

$ /usr/lib/java/jre/bin/java -version
java version "1.6.0_16"
Java(TM) SE Runtime Environment (build 1.6.0_16-b01)
Java HotSpot(TM) Server VM (build 14.2-b01, mixed mode)

Sorry 'bout that, I did have /usr/lib/java/lib/i386 when i first posted but then tested some stuff and later removed it, either way it doesn't solve ma problem.

$ which -a java

Code:

/bin/java
/usr/lib/java/bin/java
/usr/lib/java/bin/java

$ /usr/lib/java/bin/java -version

Code:

java version "1.6.0_16"
Java(TM) SE Runtime Environment (build 1.6.0_16-b01)
Java HotSpot(TM) Client VM (build 14.2-b01, mixed mode, sharing)

Ok, so i renamed /bin/java to java.bak and created a symlink to /usr/lib/java/bin/java instead.. And now i can execute java from cmd-line :/
Problem solved i guess

No Problem !

I wonder where /bin/java came from ?

I am still running Slackware 12.1 on my Laptop and I can't get at my brother's Slack 13.0-32 system right now ( logging out of KDE Kills his wireless

so I can't ssh in until he logs in again )

Now that 'we' have KDE 4.3.2 in current, I happen to have Slackware-Current downloaded and ready to install on my laptop but I can't run tar -tvf ~/extra/jdk-6u16-i586-1.txz to see the contents of the package ...

Anyhow ... Thanks for the morning diversion before I get back into my 'day job' !

-- kjh

p.s. Anybody know how one would extract a .txz package on a Slackware 12.1 system without breaking tar and *pkg* on 12.1 ?

For the future ...

I built and installed the xz binary on my Slackware 12.1 system from ~/slackware-13.0-32/source/a/xz/xz-4.999.8beta.tar.bz2

Now that I have xz, I can browse the .txz packages like so:

Code:

xz -cd <<some_package>>.txz |tar -tvf - |less -eX

I am interested in the jdk because I do a bit of Java Development so I wanted to make sure the upgrade to 13.0-32 would not break my system ...

I looked at ~/slackware-13.0-32/slackware/l/jre-6u16-i586-1.txz and ~/slackware-13.0-32/extra/jdk-6/jdk-6u16-i586-1.txz and the install.sh in each and there are no references to bin/ in the package or install.sh.
