Windows build problem

[JohnGC]

I'd be grateful for a little help please.

I have been following the instructions here;

https://opencpn.org/wiki/dokuwiki/do...piling_windows

Everything ran smoothly until I tried to build OpenCPN. This line;

cmake -G "Visual Studio 15 2017" -T v141_xp ..

results in;

Z:\opencpn_dev\OpenCPN\build>cmake -G "Visual Studio 15 2017" -T v141_xp ..

See also "Z:/opencpn_dev/OpenCPN/build/CMakeFiles/CMakeOutput.log".

Z:\opencpn_dev\OpenCPN\build>

I've attached the log file which is renamed as a PDF.

I have added the wxWidgets path to both the user variables and the system variables.
wxWIDGETS_ROOT_DIR Z:\opencpn_dev\wxWidgets

I'm using Windows 10 64-bit, it's fully up-to-date.

Thanks,

John

I'm a bit further on now.

Still following the instructions here;
https://opencpn.org/wiki/dokuwiki/do...piling_windows

I added another environment variable;
wxWidgets_INCLUDE_DIRS Z:\opencpn_dev\wxWidgets\include

It would be a good idea to add this to the instructions in the link above.

This means that I can build OpenCPN either with the command line shown in the link above or via VS17 IDE.

VisualStudio 17 gives the following error when I try to debug OpenCPN in the IDE.

Unable to start program
'Z:\opencpn_dev\OpenCPN\build\Debug\ALL_BUILD'.
The system cannot find the file specified.

Examination of the build\Debug folder confirms there are no files or sub-folders named ALL_BUILD.

But there are three ALL_BUILD files one level above in build;

ALL_BUILD.vcxproj
ALL_BUILD.vcxproj.filters
ALL_BUILD.vcxproj.user

In the VS17 IDE, ALL_BUILD is the first entry in the Object Browser.

This looks like a path configuration issue or perhaps another environment variable is needed.

I'd be grateful for a pointer to fixing this as I'm new to VS.

Try release? wxWidgets debug versions may not have been made.

I'm afraid I get exactly the same message in release mode.

The message is in a popup window and it looks as though there might be more information which isn't displayed. Any idea where that might be located?

John...

Tried to build 5.2 here and I am having big problems as well.

John...

Got there. Instead of using the command line I used CMake-gui. This allowed me to check that I was making a unicode build. It can be set up in VS but it never seems to work for me. Also the wxWidgets libraries I use are in 'vc-dll' instead of 'vc-lib', but that may be my setup.

When making the package I found I had the wrong setting for 'dialog_pi' - 'utility' instead of 'dll', so the 'dll' was not made. Rebuilt that plugin and the 'OpenCPN' installer package could then be made.

Hi Mike,

I've been trying to build from the VS17 IDE and then run in the IDE debugger. Is this a mistake?

There are loads of build warnings and trawling though them will take quite a while. Mostly they are for explicit casts and unchanged variables and can probably be ignored. But among them maybe something important!

I don't have dialog_pi in my solution explorer, should I?

The build process creates build\Debug\opencpn.exe

But when I try to run it I get a message to say wxmsw312ud_gl_vc_custom.dll can't be found. It is in wxWidgets\lib\vc_dll but I don't know how to let opencpn.exe find it. Is there an environment variable that control this or should it simply be copied to the opencpn.exe folder?

I'll persist when I have time.

John

Sorry... my mistake, should have written 'dashboard_pi'. Have not tried a debug build yet, only release.
