Я пытаюсь собрать duktape, используя профиль low_memory.yaml и включив параметры сжатия указателя. В частности, я раскомментировал следующие строки:
DUK_USE_STRTAB_PTRCOMP: true # sometimes useful with pointer compression
DUK_USE_REFCOUNT16: true
DUK_USE_REFCOUNT32: false
DUK_USE_STRHASH16: true
DUK_USE_STRLEN16: true
DUK_USE_BUFLEN16: true
DUK_USE_OBJSIZES16: true
DUK_USE_HSTRING_CLEN: false
DUK_USE_HSTRING_LAZY_CLEN: false
DUK_USE_HOBJECT_HASH_PART: false
DUK_USE_HEAPPTR16
DUK_USE_HEAPPTR_DEC16
DUK_USE_HEAPPTR_ENC16
Остальные строки остаются нетронутыми. Когда я использую утилиту Python, как это:
python tools/configure.py --output-directory ~/duktape-src/low_mem_t --option-file config/examples/low_memory_t1.yaml
Я получил много исключений:

Спасибо за совет.
