I've been working with a different processor and development environment for a few months now, and have come back to Pico RP2040 to make some program mods to an existing project. I noticed a new SDK was available and decided to give it a try.
My development environment is using Windows with MS Visual Studio 2022 Community Edition, and VisualGDB. In the past, I was able to change the PICO_SDK_PATH system environment variable to whatever SDK version I want to use; I also tell VisualGDB to use the same SDK directory path. I would delete the build directory, reload the Cmake project, and everything would compile with 0 warnings and 0 errors.
This time, with the 2.0.0 SDK, I end up with hundreds of compile errors, not just in my own code, but in SDK files as well. Here's just a small snip of the errors I get...
So, apparently it can't find the basic C types? Why would this behaviour be different from one SDK version to another? If I re-point the PICO_SDK_PATH back to 1.5.1 and tell VisualGDB to use that one ( after zapping the build directory ) I once again get a perfect clean compile.
I have a feeling that I'm missing something very simple, like a newly required variable in cmakelists.txt; but darned if I can figure it out. Is there any document for porting from SDK 1.5.1 to 2.0.0? I looked, but didn't find any.
I'll stay at SDK 1.5.1 for this current build, but would like to keep current with the latest SDK at some point.
Any ideas?
By the way, I was just able to build the entire Pico examples project with the same development environment; with only one error...so it must be something missing in my CMakelist.txt.
