-------------------------------------+------------------------------
Some of the data-model in HaikuDepot (HD) uses a custom list class
{{{List<T>}}}. There is a warning in this class because it is using
{{{memmove}}} on C++ objects which is not allowed;
{{{
../haiku/src/apps/haikudepot/textview/ParagraphLayout.h:121:36: required
from here
../haiku/src/apps/haikudepot/List.h:273:11: warning: 'void* memcpy(void*,
const void*, size_t)' writing to an object of type 'class TextSpan' with
no trivial copy-assignment; use copy-assignment or copy-initialization
instead [-Wclass-memaccess]
memcpy(fItems, other.fItems, fCount * sizeof(ItemType));
}}}
The List has a notion of being able to maintain a sort ordering in order
to speed-up searches into the list.
It is possible to stop the warning from failing the build with the
following line in the Jamfile;
{{{
ObjectC++Flags Model.cpp : -Wno-error=class-memaccess ;
}}}
One this problem is resolved; remove this line from the Jamfile if it is
there.
However perhaps a better solution would be to use {{{BObjectList}}} or
{{{std::list}}}.
