Risc-V Debian OS

[verkerkbr]

Risc-V board. Just did some test with the Starfive 2 Risc-V board.

Installed the Gnome version. Most of the applications work.

Installed the flatpak enviroment. This works. Tried to install the Flatpak OpenCPN version. No OpenCPN Risc-v version available.

Then installed the OpenCPN version from the repo of Debian.

O installed well without errors. But there was a problem with starting of O. From the terminal:

O. symbol lookup error:
/usr/lib/riscv-linux-gnu/libwebkit2gtk-4.0.so.37

undefined symbol: gst_codec_utils_caps_get_mime_codec

Hier nog een schermafdruk van het RiscFive boardje.

This symbol is from one of the gstreamer libraries, but I'm not sure which one.

I have not solved the OpenCPN start problem. Most of the applications work on this new computer trend. The XYgrib app works without problems. Internet browser, Libre office etc all work in the Ubuntu version for Risc-V Starfive board. Not yet tried the NMVe HD .

Any idea what to try next to get OpenCPN running ? Installation of OpenCPN generates no error. It is only the start error.

Interesting to note that the ARM processor on other RPI boards becomes very hot and the Riscv processor stays rather cool.

I'm not arguing just inform about an observation:
On my RPi400 the CPU temp never exceeds 45 °C whatever I let it do. How they did it with this closely fitted CPU without a fan I don't know.

Hi Hakan,

I did a simple finger-test with a CM4 board RPI4 with 16 GB EMMC on board. No SD.

In comparison with the Risc-V Starfive 2 board running from an SD.

NMVe slot on this board not yet fitted with an SSD.

Bram..
Yes the RPi4 is really hot and need a fan when in a close case.
I was though referring to a RPi400. I huge difference.

Looked at /usr/lib/riscv-linux-gnu. This folder is not available.


Avalable is /usr/lib/riscv64-linux-gnu.

Try

sudo ln -s /usr/lib/riscv64-linux-gnu /usr/lib/riscv-linux-gnu

to work it around

Still no OpenCPN on my Riscv system. However the SignalK server can be installed and works well.

Is it of any use to do a compilation on the RiscV board to get a working version of OpenCPN?

The basic Debian OpenCPN version installs without errors but does not start.

Not yet found a solution.

If you want to pursue this, you need to start debugging where the problem actually is. At some point you will probably need to build from source, but before that:
Start opencpn from commandline, any interesting output?
Look into the logfile if any is created, any interesting info?
If the program actually crashes, run

gdb -ex=r opencpn

and look at the backtrace, any interesting info?

Hi Nohal,


thanks for your reply. Took this action and the reply was the same as before. Searching on the internet gave the impression it has what to do with Gstreamer apps.


Removed most of the Gstreamer entries and now OpenCPN 5.6.2 starts !


The SignalK server was allready working on my RiscV Starfive 2 board.


Must do some further tries. And I have to switch off the OpenGL setting.


The RiscV is an interesting development.


Regards,


Bram

Here screenprint of the Risc-V running with OpenCPN 5.6.2. Os is Debian SiID.


Risc-V will certainly a new standard for computing.

[verkerkbr]

Any idea how to get the Oesenc plugin working ? Also version OpenCPN 5.8 is missing some dependensies. Although there is a version available from Debian.
