[swift-users] Is there a simple direct way to compile with libdispatch on Ubuntu?

[Isaac Gouy]

I guess I'm still doing something wrong?


module CBlock [system] {   header "/usr/include/Block.h"
   link "BlocksRuntime"
   export *
}

module Cdispatch [system] {
   header "/usr/include/dispatch/dispatch.h"
   link "dispatch"
   export *
}

$ ls /usr/include/Block.h
/usr/include/Block.h

$ ls /usr/include/dispatch/dispatch.h
/usr/include/dispatch/dispatch.h

$ ls
CBlock  Cdispatch  mandelbrot.swift

mandelbrot.swift
    import Glibc
    import CBlock

    import Cdispatch

$ /usr/local/src/swift-2.2-SNAPSHOT-2016-01-25-a-ubuntu15.10/usr/bin/swiftc -o mandelbrot -Ounchecked -whole-module-optimization mandelbrot.swift -Xcc -F-module-map=CBlock/module.modulemap -Xcc -F-module-map=Cdispatch/module.modulemap -Xcc -fblocks -I /usr/include -I ./CBlock -I ./Cdispatch

mandelbrot.swift:23:20: error: use of undeclared type 'dispatch_io_t'

mandelbrot.swift:24:5: error: use of unresolved identifier 'dispatch_io_write'

etc etc
