Hello. I have a source code for that I need to load into a core, but that code needs threading support.
When I try to compile the threaded code with e-gcc command it tells me that pthread_t does not denote a type. Is there a way to compile it without removing threads from the code?

Epiphany currently does not support multi-threading inside each core. Is there a reason you need real multi-threading? Each thread needs a stack, and memory is extremely limited. You might take a look at Coroutines or other ways to interleave code, but that will definitely need changes in your code.

Nightingale,

I'd strongly recommend restructuring the code so you put one thread on each core. I'm not sure that you could get a useful pthreads library onto an Epiphany core.

Sebraa's suggestion for coroutines is a good one if you don't need pre-emption. They can be implemented very efficiently, although you still have the challenge of managing multiple stacks.

Ok, thnx. Ended up doing just that.
It's not that I needed threads, I just hoped I didn't have to modify the code, since the library I'm parallelising is slightly convoluted.
