Assuming using a 64-bit version, some i in signature should be changed to x in
eg, c_lseek=: 'lseek i i i i' api
Did you get the changed done or can shared it with us?
find_dll need some work in 64-bit Linux. because there are both 32 and 64 bit
library installed, eg there are /lib /lib32 /lib64 , so you may want to check
the file 'libc.so.6' (without absolute path) returned by find_dll 'c' is
actually a 64-bit libc.so.6

I tried your suggestion about ulimit, and changing -v to "unlimited"

this is still far from the 200GB file I can mmap in Windows. There
might be another setting that must be changed in order to get rid of
this limitation.
Kernel tuning seems to be the best solution, since breaking the file
into smaller pieces would require extra --and complex-- code to handle
such pieces as a whole array.

It looks like linux is not designed to mmap large files, by default.
You might be able to tune your kernel, or you might have to
break the file down into smaller pieces (or hope that some day
J will introduce a bunch of complex code to work around this
problem).
But the first thing to check is whether whether ulimit -a says that
you have any memory limits active.
