problem maybe caused by PAGE_SIZE definition both inside of :
src/db/dbAttrTable.h
src/db/dbPageVector.h
rename each PAGE_SIZE by add a prefix, e.,g C_PAGE_SIZE and V_PAGE_SIZE
the problem is gone in my case.

@ic-starter Hi there and sorry for the late reply. The problem is that Alpine linux is based on musl which already defines PAGE_SIZE as a macro. This means that you cannot use PAGE_SIZE as a variable name, because the pre-processor replaces any "PAGE_SIZE" with its predefined value (it does not understand that it is not the same scope).
For now, using the docker should always work fine.
@maliberty if we want to support misc distribution, we need to rename PAGE_SIZE.

@osamahammad21 yuck. Let's rename to page_size & page_shift.
