Openbci_gui: java/bin/java: not found

[brylie]

Problem

After downloading the OpenBCI GUI 3.3.2 for Linux from the website, I attempt to run the application from the command line with

• cd path/to/extracted/files/application.linux64
• sudo ./OpenBCI_GUI

At that point, I see the following error:

./OpenBCI_GUI: /home/< username >/BCI/OpenBCI/application.linux64/java/bin/java: not found

When I look inside the java folder, I see a sub-folder named java. Inside the java sub-folder is a bin folder with the java command. So, the package seems to have one level of java folders too many.

Expected

The application should start without Java error.

Operating System and Version

Ubuntu 18.04

GUI Version

3.3.2

Running standalone app

Downloaded app

Type of OpenBCI Board

Ganglion

Are you using a WiFi Shield?

No

Note, moving the contents of the java sub-folder to the java parent folder fixes the issue.

@brylie We just updated the GUI to 3.4.0! If updating doesn't fix the issue, I'm sure it can be resolved since you've found the solution.

@andrewjaykeller is there an easy solution by changing the distribution?

@retiutut this is still an issue in the latest edition. Also moving the contents solved the issue of it not loading, however the gui is blank and white when I run it.

@winsteadworks Going to try and test

Confirmed this issue and fix using Ubuntu 18.04.1 and OpenBCI_GUI v3.4.0-beta on a MacBook Air

however the gui is blank and white when I run it.

I did not experience this issue. Make sure that the appropriate version of the OpenBCI Hub is set up correctly and run the GUI with sudo

I also noticed characters not drawing correctly in the title bar.

It seems this issue has been resolved in the latest release 3.4.0!

@retiutut ok nice this worked for me. Thanks!

[cosmobille]

ya it's a trivial fix. just edit the script & add an extra /java

[andrewjaykeller]

Did you update your hub with GUI?

[cosmobille]

I don't know what the hub is. I edited the bash script.
