How do I use cinterop on windows?

headers = Python.h
package = python
compilerOpts.windows = /I 'C:\\Program Files\\Python39\\Include'

# ignore this one, it's autogenerated from python sysconfig
compilerOpts.linux = -I'C:\\Program Files\\Python39\\Include'
linkerOpts.linux = -L/usr/lib -l python3

struct KtPyObject {
    PyObject base;
    void* ktObject;
};

I tried this but I get

Just a simple test: try lowercase file name

[martmists]

Same error. The file is also called Python.h in the path specified.

[hfhbd]

Are you sure, its called windows and not mingw_x64?

[hfhbd]

At least this is used by Ktor: https://github.com/ktorio/ktor/blob/main/ktor-client/ktor-client-curl/desktop/interop/libcurl.def

[hfhbd]

You could also take a look at https://github.com/ktorio/ktor/blob/main/ktor-client/ktor-client-curl/build.gradle.kts

[martmists]

changing it to mingw_x64 also didn't fix it

[martmists]

I also tried converting the flags from msvc to gcc but no success so far

[hfhbd]

Sorry, I dont use windows/cinterop in detail, I can't help you 😐

[martmists]

looks like I had to use double quotes
