strange Linker errors with NCS on VScode

[jonas.woerner]

I am having strange linker problems with NCS and VScode (I really hope im not just dumb and oversee something obvious here..)

I am currently migrating from PIO to NCS, and I have some problems. One of them are the strange linker Errors. I know my code is OK, because it compiles with the PlatformIO toolchain.

suddenly with NCS I get tons of undefined reference errors, and I just don know why.. I guess it has todo with the build/cmake configuration.

I made a small demo that produces only one linker error and attached it. Could somebody tell me how to fix this?

Its really funny, I always have a problem hor hours or days, and as soon as I post it somewhere I solve it :D

I added this to cmakelists.txt

FILE(GLOB lib src/libraryOne/*.cpp)

target_sources(app PRIVATE ${lib})

is this the correct way to solve this problem, or is there a better way?

Was the issue that it cound't find the reference to Rectangle::getArea()?

If so, I guess you found the source files that had these definitions. I am not familiar with LibraryOne, but it looks like you just added all the .cpp files from the src/libraryOne/ folder, and if it works, I guess that is completely fine. 

Best regards,

yeah that was the Problem. Library one was just invented by me to showcase the problem. thanks for answering :)
