Cmake and Ninja Error on Windows about swift-cmake-examples HOT 10 CLOSED

This is expected given the incorrect invocation. You need to ensure that -sdk <path to sdk> (which should be something like -sdk C:\Library\Developer\Platforms\Windows.platform\Developer\SDKs\Windows.sdk). There is the %SDKROOT% environment variable that has the path, and you can do something like:

set SWIFTFLAGS=-sdk %SDKROOT%
cmake -B build -D CMAKE_BUILD_TYPE=Release -D BUILD_TESTING=YES -D CMAKE_Swift_FLAGS=%SWIFTFLAGS% -G Ninja -S .

Note that the need for release builds is due to the debug Swift standard library not being included, and that will cause run time issues due to a mismatch between the C library ABI.

Bleh; I didn't realize that the instructions didn't cover Windows. I've updated the documentation at https://github.com/compnerd/swift-cmake-examples/tree/main/HelloWorld that you likely grabbed the commands from. Could you please report if they help?

from swift-cmake-examples.

After I used the command set SWIFTFLAGS=-sdk %SDKROOT， get result of echo %SWIFTFLAGS% is -sdk C:\Library\Developer\Platforms\Windows.platform\Developer\SDKs\Windows.sdk
But when I used cmake -B build -D CMAKE_BUILD_TYPE=Release -D BUILD_TESTING=YES -G Ninja -S ., the failure is comming.

Likely, there is nothing changed.

from swift-cmake-examples.

Yes, nothing has changed because you need to do a clean build. You should clear away build (rd /s /q build) first. I should've mentioned that. Its a quirk of how cached variables work with CMake.

from swift-cmake-examples.

thanks. But there is still report that error. Even I restart my pc, the error still exists.
Could I use the vscode's cmd terminal to execute cmds?

from swift-cmake-examples.

I had do my best to try, but i can't find the right way. could you do me a favour?

from swift-cmake-examples.

The VSCode terminal could work, but it may require additional setup to ensure that the VS setup is complete. If the output is identical, it implies that the swift flags have not been passed to CMake. Note that you are missing the required argument in the CMake invocation:

cmake -B build -D CMAKE_BUILD_TYPE=Release -D BUILD_TESTING=YES -D CMAKE_Swift_FLAGS=%SWIFTFLAGS% -G Ninja -S .

from swift-cmake-examples.

Thanks. I am using the vscode cmd terminal to do this.
Now, I execute set SWIFTFLAGS=-sdk %SDKROOT% and cmake -B build -D CMAKE_BUILD_TYPE=Release -D BUILD_TESTING=YES -D CMAKE_Swift_FLAGS=%SWIFTFLAGS% -G Ninja -S .
This error changed. Now the error is:

and the CMakeLists.txt:4 in Hellow world project is project(SwiftDemo LANGUAGES C Swift)

My VS individual component is the all in swift.org quick start page.

Do you have any idea about this?

from swift-cmake-examples.

There is something wrong with your invocation still. I cannot tell what it is because it doesn't show up in the snippets that you've posted.

The swift flags are incorrect. You are missing -sdk in front of the SDKROOT.

from swift-cmake-examples.

Bingo, i succeed finally.
I find the right way to run it at your other github repo:swift-build

Thank you very very very much.
