Visual studio code cmake causes error ld.exe: unrecognized option '--major-image-version' - visual-studio-code

Question

Using windows 10, I am trying to build example code for a W5100S-EVB-Pico.
I started in https://datasheets.raspberrypi.com/pico/getting-started-with-pico.pdf section 9.2 which sets you up to build on windows. I was able to build the examples files there using visual studio code.
Now I want to use the Wiznet. Starting in https://github.com/Wiznet/RP2040-HAT-C I follow directions in the file getting_started.md I then go to vs code, and follow the pattern from 9.2. I open the folder ...\RP2040-HAT-C\examples\http\server select the appropriate compiler, and click build. I get an error which leads me to add the line
cmake_minimum_required(VERSION 3.25)
to CMakeLists.txt Build now results in the following:

Some googling also led me to add the line
set(CMAKE_SYSTEM_NAME Generic)
to CMakeLists.txt, which now looks like
set(TARGET_NAME w5x00_http_server)
cmake_minimum_required(VERSION 3.25)
set(CMAKE_SYSTEM_NAME Generic)
add_executable(${TARGET_NAME}
${TARGET_NAME}.c
)
target_link_libraries(${TARGET_NAME} PRIVATE
pico_stdlib
hardware_spi
hardware_dma
ETHERNET_FILES
IOLIBRARY_FILES
HTTPSERVER_FILES
)
pico_enable_stdio_usb(${TARGET_NAME} 1)
pico_enable_stdio_uart(${TARGET_NAME} 0)
pico_add_extra_outputs(${TARGET_NAME})
I tried to fix the broken compiler error, which made things worse, and returning CMakeLists.txt to its former state did not get back to what is shown above. Is there some kind of 'clean' function I can do?

Answer 1

EDIT2: Tsyvarev made a very good point in the discussion under this answer. Because your CMakeLists.txt is missing a project(...) line it most likely gets implicitly called by CMake on the first line. Specific variables such as CMAKE_CXX_COMPILER or for example CMAKE_SYSTEM_NAME require to be set before the project() line. It is worth trying to update the CMakeLists.txt accordingly. However the first EDIT still holds place (which was also Tsyvarevs finding). You are most likely trying to build from an insufficient CMakeLists.txt
EDIT: I didn't notice what Tsyvarev mentioned in the comments, after looking at the appropriate CMakeLists.txt I have to agree with him. You are definitely also missing some targets and you've probably didn't give us the whole (new) error message. The missing targets here are (for example):
ETHERNET_FILES
IOLIBRARY_FILES
HTTPSERVER_FILES
You will most likely encounter errors regarding this as well. However the original error is truly tied to the set(CMAKE_SYSTEM_NAME Generic).
Original post:
A missing cmake_minimum_required() should just throw a warning not an error IIRC.
The only clean function that exists in CMake is rm [path-to-build-directory]. When you issue the cmake -S. -Bbuild command (or similar) you create a build folder where CMake generates the file needed to compile the project.
As to your issue. The set(CMAKE_SYSTEM_NAME Generic) should be added to the toolchain file or at the very least be the first variable set in your CMakeLists.txt. I believe (and this is a wild guess) that it should be before the cmake_minimum_required() this is the same for variables like CMAKE_CXX_COMPILER etc.
What I would recommend is:
Move the set(CMAKE_SYSTEM_NAME Generic) to the top of the CMakeLists.txt file
Remove the build folder.
Run cmake and build it again.
If the above won't help then I need you to clarify for me this:
By "I went back to VSCode" you mean you opened it up via the Developer prompt like the book you linked suggested.
What commands do you pass to run cmake/build it, i.e. what happens if you run from the Developer powershell/command prompt: cmake -S. -BbuildForStackOverflow -DCMAKE_SYSTEM_NAME=Generic and then build it from these generated files?

Answer 2

My mistake was opening the 'server' folder and assuming that everything was there. I never could figure out where the 'toolchain file' was. The solution is to open the folder RP2040-HAT-C in VS code first and select the appropriate compiler. VS code then does the initial cmake with the .txt file in that directory. Now, on the status line in VS code, I can click 'all' next to build, select my desired target (server) and build. Success!
Thanks to everyone who helped me with this.
