OK, I've racked my brain enough and need help. Using 0.17.2 on Linux, I have
this `proc` below.
proc segcount(row, Kn: int): int =
var cnt = 0
for k in 0..<Kn: cnt += seg[row + k].int
result = cnt
It works when I use it as below.
proc segsieve(Kn: int) = # for Kn resgroups in segment
...
...
var cnt = 0 # count for the segment primes '1'
bytes
for i in 0..<rescnt: # count Kn resgroups|bytes each
restrack
cnt += segcount(i*KB, Kn)
primecnt += cnt.uint # update primecnt for the segment
But when I try to parallelize this using spawn I get this error.
proc segsieve(Kn: int) = # for Kn resgroups in segment
...
...
var cnt = 0 # count for the segment primes '1'
bytes
for i in 0..<rescnt: # count Kn resgroups|bytes each
restrack
cnt += spawn segcount(i*KB, Kn) <-- error points to start of '+='
sync()
primecnt += cnt.uint # update primecnt for the segment
