How To build OpenCPN x64 ??

[JeongYun Kang]

I'm drawing a lot of tracks and routes, so I can see that process memory is almost at limit, as x86 (which is about 3~4GB).

So I really need to build in x64, but somehow I have several errors.

Is there any specific way to do this? or
Is it just solved in general way and it's just my problem..?

Please help

(I'm using CMAKE on Window OS,
and OpenCPN version is 5.6.0, wxWidget version is 3.1.2)

Nobody builds OpenCPN on 64bit Windows at the moment and we don't support it.
Your problems will mostly be related to Winsock, which is quite different there from Win32.
We will gladly accept a pull request resolving this stuff.

We might be investing some core team effort in this direction in the next development cycle, but the priorities are not yet set and the demand in this particular area, except your current request, has been none.

Your other option of course is to use any other platform, where 64bit builds have been supported for a very long time.
