Can not start STM32CubeProgrammer under Debian

Under Linux Debian Stretch:

- if I use the shortcut nothing happens

- if I type ./STMicroelectronics/STM32Cube/STM32CubeProgrammer/bin/STM32CubeProgrammerLauncher,

I have this error message: Error: Could not find or load main class com.st.app.Main

What should I do in order to run Cube Programmer ?

Regards

Cedric

I would guess it is not properly installed.

Most installations under Unix/Linux require root priviledges, usually realized via

sudo

.

I reinstalled it with sudo, but I still have the same error message:

/usr/local/STMicroelectronics/STM32Cube/STM32CubeProgrammer/bin/STM32CubeProgrammerLauncher

gives Error: Could not find or load main class com.st.app.Main

This was just an idea, I don't use this tool.

The announcement thread was flooded by a large amount of complaints and bug reports - I guess the test on Linux where flimsy as usual (to say the least...).

Hi Cédric,

You are surely using OpenJDK, which is unsupported. Please install oracle Java or install Openjfx package (sudo apt-get install openjfx).

It works after installing openjfx

Thanks a lot

As a general advice, you can always start a Linux GUI app from the terminal, which should give you indicative warnings/error messages in such cases.

I'm aware of that. This is actually how I got the error message.

Hi guys, did you resolved this error? I am getting the same (oracle jdk-11 with openjfx)...

> ./STM32CubeProgrammer

JavaFX Installed

chdir /opt/STM32CubeProgrammer/bin

current dir /opt/STM32CubeProgrammer/bin

that's your problem there - you say you have installed JavaFX - investigate _which_ JREs you have installed (and which one has access to JavaFX libraries).

On my Ubuntu box there are several and I am required to use a command called "update-java-alternatives" to select the appropriate one depending on which java based application I am using.
