August 15, 2007 string not aliased | ||||
---|---|---|---|---|
| ||||
Hi all,
I'm a complete newbie to D, and tried the examples on the Wikipedia page. the example 2 shows a main function like this:
int main(string[] args) // string is a type alias for const(char)[]
But, I get this error on compile:
hello.d:3: Error: identifier 'string' is not defined
hello.d:3: Error: string is used as a type
hello.d:3: function hello.main parameters must be main() or
main(char[][] args)
Is the guy writing the example wrong? Or is it my environment? (gdc
0.23, on Mac OSX 10.4)
Thanks,
--
Charles

Or is it my environment? (gdc > 0.23, on Mac OSX 10.4) The string alias was added in DMD 1.016: http://www.digitalmars.com/d/1.0/changelog.html#new1_016 GDC 0.21 was based on DMD 1.000, but I have no idea what GDC 0.23 is based on as I cannot see that info on the GDC page. I suspect it's still based on DMD 1.000 and therefore has no aliases. However, the aliases are defined in phobos and I suspect if you grab the latest phobos source and build it you will solve your problem. Regan |

The example is using D 2.0, while GDC supports D 1.0 at the moment.
(the language was split into two different versions a while ago...)
int main(char[][] args)

Or is it my environment? (gdc > 0.23, on Mac OSX 10.4) This is example of D 2, code. Who the hell published this on Wikipedia? use: int main(char[][] args) { ... } or put "alias char[] string;" before main -- Witold Baryluk MAIL: baryluk@smp.if.uj.edu.pl, baryluk@mpi.int.pl JID: movax@jabber.autocom.pl |

GDC 0.23 is based on DMD 1.007, see http://gdcmac.sf.net --anders |

Technically I guess it's D 1.016 or D 2.0 code. Am I correct about rebuilding phobos (in my reply to the OP) or will that fail utterly?

I was looking here: http://dgcc.sourceforge.net/#doc I saw the link to gdcmac and gdcwin but I didn't follow them. Regan |

GDC 0.23 is based on DMD 1.007, so that explains my problem. Thank you very much, -- Charles |

You are right, it'll probably be fixed in GDC 0.24 then. (DMD 1.018)
The aliases can probably be added to the object.d manually meanwhile
alias char[] string;
alias wchar[] wstring;
alias dchar[] dstring;
