Where do I put this code?

Hi. I'm trying to make a MicroPython build with btree included for the Pico W. But can't get it to work, has anybody had any success with it? I added diff --git a/ports/rp2/CMakeLists.txt b/ports/rp2/CMakeLists.txt

I don't know why it crashes, haven't had the time to look into it. Would be nice if it worked though. |

I did some debugging and it looks like the Pico W is running out of memory when trying to allocate the btree structure. Attaching a terminal I get the following output. *** PANIC ***
Out of memoryWhich is caused by this line in bt_open.c: https://github.com/micropython/berkeley-db-1.xx/blob/85373b548f1fb0119a463582570b44189dfb09ae/btree/bt_open.c#L190

I'm a day late and a dollar short here, but I had an interest in btree and ran into this same problem. It took me an embarrassingly long time to realise it's the classic problem of MicroPython module calling
Other than setting if(NOT MICROPY_C_HEAP_SIZE)
- set(MICROPY_C_HEAP_SIZE 0)
+ set(MICROPY_C_HEAP_SIZE 32768)
endif()Which will steal 32k from MicroPython's heap so regular C has some memory to work with. This, at least, does not hang immediately! If you want to reimplement btree's I left memory debug output in |

Uh oh!
There was an error while loading. Please reload this page.

I see btree is part of micropython libraries https://docs.micropython.org/en/latest/library/btree.html
But I cannot import btree on my Pico W.
Is the doc incorrect? Or am I missing the library somehow?
