Getting an error "error while loading shared libraries: libmpi.so.1: cannot open shared object file: No such file or directory"

Question

Getting an error "error while loading shared libraries: libmpi.so.1: cannot open shared object file: No such file or directory" while running veins simulation in Omnet++

EDIT:

I reinstalled the omnet++ and now I am getting this error:

Answer 1

First error:

Either of two things may be happening (or both):

1 – You do not have the specific lib (unlikely because the compiler and linker would have built and linked with the library symbols).

2 – The path is not correct and the binary at runtime cannot locate the lib correctly.

I assume you are using a Linux flavour, I also noticed that you have a double set of colons appended within both your environment variables i.e. ( :: )

$PATH
$LD_LIBRARY_PATH

Which could be the result of you appending the paths to the variables incorrectly (try removing one of the colons by appending the environment variable again without a colon).

For example:

Appending to existing environment variable

print my current environment variable to console: (same for LD_LIBRARY_PATH)

VirtualBox:~$ echo $PATH
/usr/local/polysync/utils/x86_64.linux/bin:/usr/local/polysync/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

Append a new path to the end of $PATH

export PATH=$PATH:/boom/yea

VirtualBox:~$ echo $PATH

/usr/local/polysync/utils/x86_64.linux/bin:/usr/local/polysync/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/boom/yea

Scroll along to see the appended path.

The following post describes the process very well:

https://unix.stackexchange.com/questions/26047/how-to-correctly-add-a-path-to-path

Also check you have the lib by using:

VirtualBox:~$ sudo find / lib | grep libmpi.so.1

Hope this helps. You will need to log out and back in for Eclipse to see the changes. Would also be helpful if you posted strings instead of a screen shot (copy and paste the console output for eaxmple).

Answer 2

Second error:

The almost certainly a Java SDK/JDK version problem or path problem preventing the Eclispe enviroment from starting.

Check your Java version:

$ java -version

Because of the

-Dosgi.requiredJavaVersion=1.7

output in the error log suggest its looking for 1.7.

Then check this post describing many solutions to this problem:

Can't start Eclipse - Java was started but returned exit code=13
