Hi Fabio,

Right, the PyInterpreterState structure is now opaque. You need to include pycore_pystate.h which requires to define the Py_BUILD_CORE_MODULE macro. That's the internal C API which "should not be used", but it's ok to use it for very specific use cases, like debuggers.

Maybe we should provide an interpreter method to set interp->eval_frame, to avoid to pull the annoying internal C API.

Hi Victor, Thank you very much, that did the trick! I agree it'd be nicer to have some method to set up the frame evaluation function instead of pulling up the internal C API, but it's also *very* specialized, so, I'm not sure how much it's worth it (I'm happy with just being able to do it, even if it's not very straightforward).

Hi All,

I'm trying to upgrade the pydevd debugger to the latest version of

CPython (3.8), however I'm having some issues being able to access `PyInterpreterState.eval_frame` when compiling, so, I'd like to ask if someone can point me in the right direction.

...

What I'm trying to do is compile something like:

#include "pystate.h" ... PyThreadState *ts = PyThreadState_Get(); PyInterpreterState *interp = ts->interp; interp->eval_frame = my_frame_eval_func;

and the error I'm having is:

_pydevd_frame_eval/pydevd_frame_evaluator.c(7534): error C2037: left of

'eval_frame' specifies undefined struct/union '_is'

...

So, it seems that now "pystate.h" only has a forward reference to "_is"

and a typedef from " PyInterpreterState" to "_is" and "_is" is defined in "include/internal/pycore_pystate.h", which doesn't seem like I should be including (in fact, if I try to include it I get an error saying that I would need to define Py_BUILD_CORE)... so, can someone point me to the proper way to set the frame evaluation function on CPython 3.8?

...

Thanks,
