hi guys,

installed jdk on my centos7 box

but when i type javac i get:
bash: javac: command not found...
Similar command is: 'java'

and when i go whereis javac i get:
/opt/jdk1.8.0_91/bin/javac

i added the above to my path:
]$ echo $PATH
/usr/lib64/qt-3.3/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin:/home/wbrandt/.local/bin:/home/wbrandt/bin:/opt/jdk1.8.0_91/bin/javac

dont think its a path thing
when i:
[wbrandt@localhost bin]$ javac
bash: javac: command not found...
Similar command is: 'java'
[wbrandt@localhost bin]$ ./javac
bash: ./javac: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory

the above is when im in the opt directory:
/opt/jdk1.8.0_91/bin/


why cant it work?
also if i need it to run everytime do i need to add it to another config file?

It has to be on your search path to find it - Make sure the path to the command is in the PATH environment variable list.

You might also check to see if there is a module command that will set up your environment for java. I believe RH has the module command that is used to evaluate configuration scripts for various facilities.

There is also google - that shows http://introcs.cs.princeton.edu/java...linux-cmd.html

thanks jpollard,

turned out i was missing a glibc package of some sort,installed it
changed the path in my .bash_profile
javac is working fine
