2014-02-14 15:48 GMT+08:00 Alex Hornung <[email protected]>:
In the relevant CALL_MMAP in src/lj_alloc.c, luajit tries to mmap at
a specific address (MMAP_REGION_START). It then checks whether the
address returned by mmap() is between MMAP_REGION_START and
MMAP_REGION_END. If it isn't, it fails.
However, our mmap() will not try to actually allocate at the passed
address without MAP_TRYFIXED (for right or wrong - haven't looked at
our mmap yet). Adding MAP_TRYFIXED to the MMAP_FLAGS solves the
problem and luajit starts up.

OK,I find the reason.
ktrace must be config in kernel
I will build the custom kernel and try again.
2014-02-14 15:06 GMT+08:00 lhmwzy <[email protected]>:
I'd like to provide,but how to
#cd cd LuaJIT-2.0.2.patch/src
#ktrace luajit
ktrace: ktrace.out: Function not implemented
2014-02-14 14:50 GMT+08:00 Alex Hornung <[email protected]>:
Can you provide a ktrace(1) output? Just ktrace luajit, and then
kdump and get the output.
Cheers,
Alex

It looks like it's trying something specific; assuming it's really
not supported on DragonFly, you could look in the file and see if
it
has a fallback for other operating systems that don't support this
feature and add DragonFly to that fallback.
