Comment (by arvindsraj):
There's a small issue in setting value of HAIKU_BOARD_LOADER_ENTRY_NBSD
relative to HAIKU_BOARD_LOADER_BASE. Jam doesn't support arithmetic which
makes assigning a value to LOADER_ENTRY_NBSD slightly tricky. I tried
invoking Add from build/jam/MathRules as
{{{
HAIKU_BOARD_LOADER_ENTRY_NBSD = [ Add $(HAIKU_BOARD_LOADER_BASE) + 8 ]
}}}
but that doesn't work because a hex value is passed to Add, which is
classified as NaN by the rule Num. I don't think the other rules(AddNumAbs
and AddNum) are meant to be invoked directly. One solution is to add a
rule that accepts hex values but that might be too much work right now.
Another solution is to perhaps perform all computations in sh using printf
and bc perhaps. The problem is that this variable is passed directly to
mkimage and thus should be a hex string.
