Java is installed, in listing, but execution produces “./java: No such file or directory”

Question

I just ran the script below and it fetches and unpacks the JDK into the correct location. Problem is that every java command (as copied to /urs/bin) gi

Answer 1

I was getting the

bash: /usr/bin/java: No such file or directory

The issue was I installed the i586 version of Java on a x86_64 Debian.

The fix: I removed it and install the x64 version of Java. Everything is working fine now.

Answer 2

You're running on a 64bit system without a 32bit runtime environment.

Assuming ubuntu/debian issue:

apt-get install libc6-i386

Or you should install the 64bit version of the package into this VM (which is probably the best solution).

The error message is coming from the run-time linker/loader. if you do a readelf -l java you will find a line like:

 [Requesting program interpreter: /lib/ld-linux.so.2]

Which is what you expect for a 32bit application, and you probably don't have the 32bit environment installed - check with an ls -l of that program interpreter.

and example for a 64bit program would look like (your system may vary):

 [Requesting program interpreter: /lib64/ld-linux-x86-64.so.2]

If this is not the case, and you do have the 32bit libc installed, you can try an ldd java, which will give a listing like:

linux-gate.so.1 =>  (0xf76ef000)
libpthread.so.0 => /lib32/libpthread.so.0 (0xf76b3000)
libjli.so => /home/bubba/java/jdk1.7.0_02/bin/./../jre/lib/i386/jli/libjli.so (0xf769f000)
libdl.so.2 => /lib32/libdl.so.2 (0xf7699000)
libc.so.6 => /lib32/libc.so.6 (0xf751f000)
/lib/ld-linux.so.2 (0xf76f0000)

if there are lines saying not found then you should add pagkages providing that, but as you can see from this ldd all the dependencies are core libraries that should be present on practically all linux systems.
