Question

I’m trying to compile a hello-world app:

8g test1.go -o test1.8

Error:

open -o: No such file or directory

Irony here being that this works fine when I leave off -o:

8g test1.go

How do you specify an object filename to go command line compiler 8g?

(8g version release.r60 9481)

Answer 1

When 8g is run without arguments, it prints something like this:

gc: usage: 8g [flags] file.go...
flags:
  ...
  -m print optimization decisions
  -o file specify output file
  -p assumed import path for this code
  ...

Notice that [flags] are positioned in front of file.go. This ordering needs to be respected when passing arguments. This is unlike gcc which accepts options and files in any order.
