OpenCPN SIMRAD/LOWRANCE Radar Overlay PlugIn

Robbie...
What's even more puzzling is that AFAIK there never was a 0.95 version. Are you sure it does not complain about the "AIS radar" plugin, which had a 0.95 version (now blacklisted because it contains errors)?

Figured out how to do a screen capture...

... so I dont think its the AIS plugin.

EDIT: I ran the uninstall option for the br24radar_pi_1.0-1_i386 package and restarted OCPN. The error message no longer appears. The only non-standard plugin is the Weather Fax one which I'd not seen before

Robbie...
It definitely is a conflict with blacklisting the AIS radar plugin...
Actually more a bug in the OpenCPN core.

Ok, thanks Pavel - can I leave that one with you then please

[nohal]

Yes. What's puzzling though is that 1.0 evaluates as less than 0.95... That should never happen and actually does not for me. Weird.

Pavel..
What's also weird is that BR24radar_pi is black listed at all. Kees couldn't use any minor number than 96 without getting thrown out.
Pluginmamanger:602 is checking name, major and minor version but the name itself should be enough to not evaluate true?
But, I'm not sure of the "EndsWith" below. Could it be that BR242Radar_pi and AISRadar_pi are enough to make them equalised? In that case we may consider another logic?

if( ( PluginBlacklist[i].all_lower &&  name.EndsWith(PluginBlacklist[i].name) &&  PluginBlacklist[i].version_major >= major &&  PluginBlacklist[i].version_minor >= minor )

Hakan...
Exactly. This, in combination with https://github.com/OpenCPN/OpenCPN/b...nmanager.h#L84
Still it does not explain the message though, if you look at the conditions, 1.0 simply is more than 0.95 and the message should not be displayed...

Pavel

[Hakan]

Pavel.. No I can't either see why. I know it's working in Windows although DOS are not known for a logic sorting of numbers, but it can't ever be that Linux have some equal mismatch --or??

This thing is pretty platform dependent. As you can see in the fix at https://github.com/nohal/OpenCPN/com...f4d53434417256
Anyway, it should be solved, I hope...

Pavel

[Hakan]

Pavel..
Yes, I've debug tested your change in W and the way you got rid of "Class " is working so this would be a nice fix.
Thanks

Hi Pavel,
Just tried the latest beta, 2330, but I guess your fix isnt in that. If there is a binary I can use to test with I'm happy to do that but I'm not set up to extract & build OCPN.

Cheers ... Robbie

[Hakan]

All for info...
Thanks to Douwe's tips I've tried tcpreply, a Linux program to broadcast a Wireshark capture on my local network to simulate a radar scanner.
Using: sudo tcpreplay --loop=5 --intf1=eth0 Test3W.pcapng
Results in a nice scanner picture on my Win PC connected to the same local network.
See the picture where I use a VDR play to get a heading and as you may see the VDR and radar capture are not from the same location.

I've been with a Ubuntu on a spare PC! Rather fun actually and I thought some struggling should end, at least based on you Linux "natives" sometime indulgence comments to other OS's
I've installed the official 3.3.2330 and Canboat's BR24Radar_pi.deb and received the blacklist version <= 0.95 message! Are your changes not included in 2330 or is my memory not up to date?
The log says: "Cannot open shared object file: Permission denied"
I haven't yet started handling source in Linux so I can't see what's going on.
Thanks for info/

Pavel..
Yes I will copy that but meanwhile:
On github.... pluginmanager.cpp:611
The sorting out of Windows "Class " is there but he "all_lower" are there again? And the message in Ubuntu was complaining about: Radar_pi

for (int i = 0; i < len; i++) {                                        if( ( PluginBlacklist[i].all_lower && name == PluginBlacklist[i].name && PluginBlacklist[i].version_major >= major && PluginBlacklist[i].version_minor >= minor ) ||                                            ( !PluginBlacklist[i].all_lower && name == PluginBlacklist[i].name && PluginBlacklist[i].version_major == major && PluginBlacklist[i].version_minor == minor ) )

Didn't you changed to something name = name ??
