Any tips for setting up vscode for native module development?

[lerouxb]

Starting with a new project that's just the basic factorial natmod example from here https://docs.micropython.org/en/latest/develop/natmod.html

I have that open in a workspace in vscode. I'm getting a lot of expression must have struct or union type but it has type "const int" errors. I'm wondering if anyone's done the work of configuring vscode to work with this?

I found the vscode page on the wiki https://github.com/micropython/micropython/wiki/VS-Code but it doesn't seem to deal with setting things up for c.

I'd love some pointers if possible.

@lerouxb The problem here is that whatever is powering the vscode popup doesn't understand the magic of where mp_fun_table comes from, because it doesn't know which preprocessor flags need to be set. (in this case MICROPY_ENABLE_DYNRUNTIME)

See the end of py/nativeglue.h -- it sees extern const int mp_fun_table; but it should see extern const mp_fun_table_t mp_fun_table;.

I'm not sure the best way to fix this... are you able to configure vscode to know about the following flags that py/dynruntime.mk sets:

CFLAGS += -DNO_QSTR
CFLAGS += -DMICROPY_ENABLE_DYNRUNTIME
CFLAGS += -DMP_CONFIGFILE='<$(CONFIG_H)>'
