Hi Lou,

You may need to tell Python where to locate the escript library files by adding the escript library folder to LD_LIBRARY_PATH. You can do this by running the command

eval `run-escript -e`

in your console. (Note that you must use the back tick symbol, not an apostrophe.) If you add this command to your ~/.bashrc file then your console should run it automatically whenever you open a new console window.

I have run the command, eval `run-escript -e`,but it didn't work.
bash: cd: /home/ljc/OpenFOAM/ljc-6/run: 没有那个文件或目录(There is no such file or directory )
My escript source directory is /home/ljc/escrpt/src

And I have try to add this command to my ~/.bashrc
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/ljc/LIGGGHTS/LIGGGHTS-PUBLIC/src:/home/ljc/escript/src
but it didn't work either.

Hi Lou,

I think you may have to add this command to your ~/.bashrc file:

export LD_LIBRARY_PATH=/home/ljc/escrpt/src/lib:$LD_LIBRARY_PATH

If that does not work, can you please run this command and tell me what the output is?

/home/ljc/escrpt/src/bin/run-escript -e
