No.

2. What is the preferred (aka easiest) Linux distro to use for compiling and testing new plugins ?

Any you are familiar with. If none, Ubuntu.

3. Related to 2. Does a Raspberry Pi have sufficient memory and processing power to compile and test plug-in's ? It is a potentially attractive platform as there a number of CAN bus hats available for the Raspberry Pi.

[/QUOTE]
Yes, given you have sufficient time. Of course it is by at least an order of magnitude less powerful than any modern x86 machine.

Hi stevead. Pavel, I've set up VM box with Windows10 and a dev for 4.99, should I use ubuntu for a linux vm? Should i use most current stable?

Not sure if this is the right place, so please point me to one if appropriate. I've made a ton of KAPs for SE Asia (charts here are shocking) but I'm finding that OCPN is getting less stable with recent versions, especially when I have lots of KAPs loaded. Generally have CM93v2 as normal charts, but will sometimes have maybe 15,000 KAPs loaded (12GB). Recently I've noticed OCPN getting unresponsive or showing a continuous circle (for the mouse) after scrolling around while navigating for a while. It usually recovers if I shut it down & restart it, but sometimes I have to nuke the CHRTLIST.DAT file & let it rebuild its chart database, or even edit the OpenCPN.INI file to reduce the number of KAPs I have loaded before it starts behaving again.

I'm sorry I can't give better repro here, but I've got my KAPs available on our Downloads page if anyone wants to futz with them. Loading up, say, all of Raja Ampat (NE Indonesia) & then scrolling around & in/out will often produce problems. Setup here is Win10, Acer Aspire V17, Intel i7 quad, 16GB (more details on request). I'm not using OpenGL (so not sure if the GeForce GTX 860M is doing anything) but I do set the Raster Zoom/Scale weighting to +5.

I guess what I really want to know is if there's a limit on how many KAPs I can load up? And if so, is there anything I can do to increase that? TIA!

There is a feature called something like "texture caching" in advanced display options. Try turning it off and on to see if anything changes. Without OpenGL it may be off already.

I think you will want to use OpenGL for faster response. Why do you have it off?

[Jon Hacking]

Dan, it defaults to Off, so I left it. I'd also heard negative comments about OpenGL, but they weren't from truly knowledgeable sources, so I'll happily try it on. And yes, texture caching is only available with OpenGL enabled.

What are the pros & cons of using OpenGL with OpenCPN?

[transmitterdan]

Jon,

OpenGL is hundreds of times faster than drawing using the main cpu. I think texture caching is available with OpenGL off. Please have a look.

OpenGL sometimes doesn’t work right. But when it works (95% of the time is does) it speeds up OpenCPN drawing a lot.

I will have a look at the problem after the 12 hour download from your web site.

[Jon Hacking]

Thanks, Dan. I'll try it with OpenGL & see if that helps.


Yeah, those KAPs are huge, but I've had so many requests for them that I put that page together just a few days ago. And if it will keep cruisers safer...

Have installed VirtualBox and made several VM with Win10pro + MS Visual Studio 2017 + Poedit, + Cmake + NSIS + Git + Git Desktop, etc. I've downloaded the latest Opencpn/Opencpn master from 6 days ago and run cmake from the build directory.

I see that MS is trying to use my OneDrive. I had not intended that.
Is this normal? I am a bit confused about this. Should I change it?

Does anyone know what is causing this?

I have installed POEDIT and added the path to Poedit.

[rgleason]

I corrected the path to be "C:\Program Files (x86)\Poedit\GettextTools\bin"

and now get other errors:

[rgleason]

The message says " Could NOT find Gettext (missing: GETTEXT_MSGMERGE_EXECUTABLE
GETTEXT_MSGFMT_EXECUTABLE)"

There is an "xgettext.exe" in C:\Program Files (x86)\Poedit\GettextTools\bin" directory.
Is that what is needed?

no, msgmerge.exe is what is needed. And it is there, so your problem is something different - either you have the path still wrong or did not refresh your environment, which in your case is probably easiest to do by a reboot and of course cleaning your build directory completely.

[rgleason]

This is the file that issued the error:

include(${CMAKE_CURRENT_LIST_DIR}/FindPackageMessage.cmake)

# internal helper macro
macro(_FPHSA_FAILURE_MESSAGE _msg)
if (${_NAME}_FIND_REQUIRED)
message(FATAL_ERROR "${_msg}")

Ah ah, I have to shutdown and restart.

[rgleason]

Reboot worked, and it is compiling now, but why oh why is it on onedrive?
Won't that create lots of upload/download that is unnecessary?
Is this what MS does now for some "sharing code" reason?
It's a lot slower with one processor in a VM.

Pavel, just saw your message. You nailed it. reboot. Thanks.

It is on OneDrive because you put it there, nothing to do with Microsoft. Put it elsewhere if you like.
