Windows build problems

[zhangyu8730]

I want to build and use OpenCPN in win10 environment. Visudal studio 2017 was used and the process suggested in the manual was performed.
Unfortunately, the following CMAKE error occurs while building OpenCPN. how can i solve it?

When I run [ cmake -G "Visual Studio 15 2017" -T v141_xp ..]
it shows as below.

          You are missing dependencies. The complete instructions are available at https://opencpn-manuals.github.io/main/opencpn-dev/windows.html

The batch scripts mentioned there for either of the workflows will take care of populating the dependencies for you.

You are using outdated docs, correct ones could be found here

You are also using an outdated build environment, building these days is documented for Visual Studio 2019.

No bug to be found here, converting to discussions

EDIT: building these days is documented for Visual Studio 2019/2022

Please provide a link to the instructions that you were using. We will remove that. Thank you.

@rgleason : The complete https://opencpn.org/wiki/dokuwiki/doku.php?id=opencpn:developer_manual is probably just a source of confusion. Please consider removing it completely, at a glance I can see numerous errors that will not get fixed. if you still want it around, please mark each and every page with "DONT USE THIS OLD INFO FILLED WITH ERRORS" or so. Remember that users often finds pages using google rather than following the TOC links (that's how I found the link above)

[rgleason]

Okay, so google is the problem. I am not going to put a message on each page. Deletion requires deletion of each page so it will take awhile unless I find some other way. Give me a day.

[rgleason]

@Rasbats Okay, most of it is gone. I left the Dev Beta Plugins https://opencpn.org/wiki/dokuwiki/doku.php?id=opencpn:developer_manual:plugins
Can we delete these now? I note VDRplus which I've always hoped would become a full fledged pi.
Are these all in the new Beta Plugins catalog?
What about Autopilot Fenix?

[rgleason]

Whoops, I deleted some of those Beta PI. Sorry, can't retrieve them. Some are left however, can they be deleted now?

[oplaydo]

What about Autopilot Fenix?

Not mine.

Engine_Dashboard and Race_Start (sic) belong to Steve Adler

TideFinder, oBabel and NetCDF are mine but they can be deleted.

[Rasbats]

@oplaydo is owned by @Rasbats

[rgleason]

Ok will delete all tonight

[rgleason]

Dev manual and other is removed. Keeping part of old manual for confirmation before deletion.
Wiki is cleaned up considerably.

[rgleason]

@Rasbats I have a backup and can retrieve playdo and send to you compressed.

[Rasbats]

@rgleason Not desperate as it is well outdated. But if you make time in the future. Thanks.

[rgleason]

Thanks, I will do it.

[rgleason]

OP Used incorrect outdated documentation. This documentation is now deleted.

Hello,
using the most recent instructions for building on Windows ( VS2022)
impossible to build the debug version. any help please ?
Thx

[transmitterdan]

Yes, this is a known and reported issue. Non-debug builds are ok. I suspect it's a compiler problem but several updates of Visual Studio have not changed the situation.

When I get some time I may report it to VS developers for their opinion. Been too busy with personal matters lately.

[Hakansv]

In VS022 I build with RelWithDebInfo and can debug what's needed. Sometimes I've to change the default Optimization for a single file*) to see all values.

*) In Solution Explorer right click a source file and select Properties. In C++ Optimization change to "Disabled".

[transmitterdan]

I suspect this is a compiler bug. I believe it has to do the whether or not a compiler created function (from a template) is inlined or not. When inlined then this error does not happen. But when it creates a real function then it becomes confused as to the certain type conversions (contortions) and gives up.

This is not seen with any other compiler except Microsoft and only in Debug builds which further suggests it's a compiler bug.

If someone wanted to bring this to the attention of Microsoft it might help.
