combination not supported: Threaded/Profiling when building NDP library

[Ben Gaster]

H Shelarcy,

Thanks for your reply.

I have removed the -threaded when building the library and now
everything builds correctly and the examples are all working. However, I
would like to explore porting the library to use a small FFI library
which will allow exporting flattened data parallel operations to a
vector array processor that I'm working with. With this in mind I wanted
to check that as this the library is not concerned with SMP and thus I
will not expect the ported version of NDP to call GHC's SMP concurrency
primitives, as I believe it does at the moment, then I need not be
concerned with this option not being enabled, even at link time?

Regards,

Ben
