PhotoLayer plugin - Satellite GeoTiffs with transparency

[scpeters]

Mike,

Updated catalog and it still tries to grab the 3.1.21 install image.

A few bits of other information I've gleaned related to other threads:

Hardware is 8GB Raspberry pi with an Openplotter image and OpenCPN version 5.2.4. Upgraded all software and OS to latest using apt update and apt upgrade. Seems like all is up to date.

I am fairly sure this is on 32 bit OS, given the below:

pi@openplotter:~ $ uname -m
armv7l

The head of the Opencpn.conf file has the blank lines for CompatOS etc. When I fill in 'Ubuntu' and '18.04' none of the plugins show as installable in the OpenCPN control panel. I've updated the plugin catalog with the CompatOS set to these values, and also blank. Still no luck installing photolayer, or it attempting anything other than 3.1.21. My next step was to URL hack the plugins.xml below to point to a different source. Not sure that is wise. At some point the square peg can't be forced into the round hole. See next code box below this one.

Any suggestions for next steps?

Thank you,
Steve

..Forgot to mention that I was able to install Weather Routing and Konni Logbook plugins and they both seem to work as expected.

Steve...

Could you try running this:

cat /etc/os-release

This will give us the OS you are running.

I have the same problem in Ubuntu 20.04.

The "photolayer_pi-3.1.27" is not available in the master catalog, no matter how much I update.

Also.... when using your latest git-code I get this error when compiling....

Thomas...

Thanks for the feedback. I will update my Ubuntu to 20.04 and have a look at this.

Thanks. The plugin will need some work.

Mike,

Thank you for letting me know. I can test anything you like...

Steve

scpeters et al...

PhotoLayer has been rebuilt(thanks Alec). Now runs on Ubuntu 20.04 and there are installers for other OS. Perhaps you can update the Master catalog and give this a test.

Mike

[Rasbats]

Other than Windows you need to make sure libgeotiff is installed on your system.

Hi Mike,

Thank you for speedy work on the plug-in.

I updated the catalog and gave it a try. The install proceeded very well. Version 3.3.1+3104 installed without error. When I go to enable it, however, I have an error, different from before.

From the log file:

20:25:53.758 MESSAGE pluginmanager.cpp:1174 Checking plugin candidate: /home/pi/.local/lib/opencpn/libphotolayer_pi.so
20:25:53.761 MESSAGE pluginmanager.cpp:2169 Plugin is compatible: true

20:25:53.763 MESSAGE pluginmanager.cpp:2291    PlugInManager: Cannot load library: /home/pi/.local/lib/opencpn/libphotolayer_pi.so

The plugin appears to have some trouble loading. It seems to be looking for a library called libGLU that is not found. Should I install it independently, or should it come with the plug-in?
FYI - I do have libgeotiff installed.

pi@openplotter:~ $  apt list | grep libglu

OK - so I got bored and installed libglu1-mesa-dev... And it seemed to fix the dependency.

pi@openplotter:~ $ sudo apt-get install libglu1-mesa-dev

now on to the next error. Guessing I am missing a few packages that are needed - as this one is very similar... Will wait for those who know more to point me in the right direction!

Steve... Not able to test here but from Googling:

sudo apt-get install libjsoncpp-dev

Mike

[cagney]

On Ubuntu 20.04 /64 the generated package when I compile is named .....-x86_64.deb. This is wrong and generate a "wrong architecture" error.
It's a question of naming, where the correct name (though not logical) is
...._amd64.deb. This was OK in earlier versions for ex. 2.1.2.

Thomas...

To help my sanity does the version installed from the Master catalog work?

Thanks.
