763 :: standalone 32-bit?

• arisi (orginal) [2015-01-18T00:39:53+01:00] view original

  Hello,

  just found Nim. This is nice -- CoffeeScript made js-stuff fun, this can make the same for gold old C !

  Despite a long session of google-fu, I have not figured out:

  howto make compile standalone for arm cpus?

  when one tries combination:

  --os:standalone --cpu:arm
  Run

  results in:

  /home/arisi/projects/Nim/lib/nimbase.h:385:13: error: size of array 'assert_numbits' is negative
  typedef int assert_numbits[sizeof(NI) == sizeof(void*) && NIM_INTBITS == sizeof(NI)*8 ? 1 : -1];

  which according the header is indication of mismatch in word length -- as expected.

  It seems one must decipher configuration scripts to remove 16-bit setting from standalone option ?

  --os:standalone should not imply a 16bit architecture. My guess it's a 32bit vs 64bit mismatch. Setup your GCC properly for ARM and it should work.

  Well... I do have compiled successfully with gcc for arm cortex..

  And nim docs say:

  "The standard library can be avoided to a point where C code generation for 16bit micro controllers is feasible. Use the standalone target (--os:standalone) for a bare bones standard library that lacks any OS features."

  Standalone option seems to be hardwired for 16-bits.. which is not quite useful.

  Standalone is not hardwired to 16 bits. When I compile tests/manyloc/standalone/barebone with --cpu:arm it clearly emits #define NIM_INTBITS 32. In fact, the test breaks with cpu:avr (now fixed in devel).
