4628 :: standalone with strings

• markprocess (orginal) [2019-02-05T21:40:21+01:00] view original

  Is it possible to create a standalone project that uses string operations like concatenation? I am trying to link nim to a unikernel (Ultibo) on the raspberry pi which has more resources (especially 1GB memory) than a microcontroller but in this case is being used like an embedded system Thanks, Mark.

  The real question is here why you need --os:standalone. What feature/implementation detail of system.nim prevents you from using it in its standard setting?

  Well, I started with os:standalone because Ultibo does not have a linux api so I can’t use os:linux nor any of the other choices. Perhaps what I don’t know is how to link a memory-only (no os calls) nim program to ultibo. What would be easiest would be for the nim entry point to receive a large one-time memory allocation for its heap with no os calls at all. The benefit is being able to use the nim language calling the rich ultibo raspberry pi resources through importc calls.

  I will look at system.nim. Thanks.
