Unable to build in Visual Studio Code about pico-sdk HOT 11 CLOSED

you need to run it from a visual studio developer command prompt (or whatever it is called)

from pico-sdk.

Just for the sake of completeness (not that it really matters, because our instructions say to use nmake), but it turns out that the problem with ninja is that GCC outputs dependency-information in a slightly-incorrect format that ninja can't understand.

EDIT: ...which in turn has been fixed in the master version of ninja, ninja-build/ninja#1774 but seems like it isn't yet included in a released-version of ninja.

from pico-sdk.

The fix for ninja-build/ninja#1774 are included in ninja release 1.10.1 and later

from pico-sdk.

I think there is a problem with the ninja CMake generator and pico-examples, can you try setting "NMake Makefiles" as the preferred/default build generator in CMake plugin settings?

Excellent, that fixed it, many thanks kilograham :). So for everyone else, you need to add the "NMake Makefiles" to the Settings tab of the extension under the entry labelled:
Cmake: Generator
The CMake generator to use

Should look like this

from pico-sdk.

Also if you are using VS Code on something other than Windows you likely need to change this to "Unix Makefiles"

from pico-sdk.

I've now updated the documentation to reflect this, will be available in the next docs release expected today.

'nmake' is not recognized as an internal or external command,
operable program or batch file.

I follow the instructions in pdf running on Windows. All good until trying to run nmake.

Thanks a lot. It works. You save me a lot of time and headaches. I still have to figure out how to use VSCode. Is it possible to use J-Link for debugging on Windows?

from pico-sdk.

I've now updated the documentation to reflect this, will be available in the next docs release expected today.

You may also have to specify not to skip installing the Windows 10 SDK from VS build tool installation step. Because not installing the SDK will cause NMAKE to fail. Installing the Windows 10 SDK solved an error I encountered later.

I'll add a note to the Getting Started book to this effect.
