Compiling OCPN on Windows (VS 2010)

[Mollymawk]

I'm trying to build OCPN on Windows, using Visual Studio 10, following the instructions at Compiling - Windows | Official OpenCPN Homepage.

I've followed the instructions to the letter, but when I get as far as building OCPN I get an error because Cmake can't find wxWidgets.

C:\Users\Administrator\code\OpenCPN\build>cmake -G "Visual Studio 10" ..

I'm probably being stupid but I can't work out why it can't find it...
I have added the vc_dll dir to the PATH and created the WXWIN env variable. Restarted a couple of times. No joy.

My PATH:

I built wxWidgets according to the instructions on the wiki page, and yes, I did change the two config lines in setup.h. (I forgot the first time, but then I changed and rebuilt.)

Doesn't work with Cmake-GUI either, though the correct paths to wxWidgets DLLs and wxWidgets root are shown.

Any ideas anyone?

Caesar i don't see a path to wxwidgets-2.8.12 but maybe i am missing it. I believe my setup has a path setting for wxwidgets. I will check my setup when i get home.

Rick, it's on the last line there, C:\wxWidgets-2.8.12\lib\vc-dll

[rgleason]

Sorry now i see it. Be very careful editing PATH as any little mistake trips you such as period instead of comma or leaving a space etc. I cant pick this stuff up with small text.

Have you compiled wxwidgets or did you download the binary?

[rgleason]

Yes you did build wxwigets. It is a problem with wxwidgets. Is your path right?

I followed the instructions on the Wiki page, which seems to be a kind of hybrid - download the setup.exe package, but then change some config and compile.
I suppose the setup.exe doesn't actually install a binary, it just copies the sources onto the disk.

Well, it seems right, as it does contain C:\wxWidgets-2.8.12\lib\vc-dll which is thecorect paht to the location of the wxWidgets DLLs.

Caesar...
Try changing it to just

C:\wxWidgets-2.8.12

[Mollymawk]

Pavel, thanks, that worked!

(Also no need for WXWIN variable, it seems, as I deleted that and it still works.)

Shall I update the build instructions on the wiki, or is there some situation when using the full path to vc_dll would be right?

[nohal]

Yes, please...
Might be that the logic got changed in recent cmake versions - my cache is populated for years, so the instructions were actually not checked for quite some time.

Hmm...
It doesn't build.
Takes a long time, seems to build loads of stuff, then finally a massive number of errors.

Seems the Windows command prompt doesn't have a very long scrollback, so I can't see the first errors, but what's on the screen at the end is this:

Are you absolutely sure that you built wxWidgets correctly? = you cleaned all the build products before doing it last time

Yes actually I uninstalled and deleted the whole wxWidgets folder and installed and compiled from scratch.

[nohal]

Did you build both debug and release configs for WX? Looks like you are exactly at the same spot as https://forums.wxwidgets.org/viewtopic.php?f=19&t=36381
Remember that OpenCPN builds Debug by default.

[Mollymawk]

Oh, no, is it necessary to build both? That wasn't clear from the wiki, it just says "If you want to fully debug OpenCPN you must build the wxWidgets debug DLLs also".
So no, I only built release. I will try debug too now.
