When I give dmd untitled.d command in my ubuntu maverick 64 bit laptop I get
the following error.
object.d: Error: module object is in file 'object.d' which cannot be read
import path[0] = /etc/../../src/phobos
import path[1] = /etc/../../src/druntime/import
I tried all morning to solve this
OK, now I have a question about passing variables. In D, I have a
dynamic array of strings and I want C to get that array. Yet C
supports neither dynamic arrays nor strings. So is there a way to
accomplish this?

To use a D data structure from C you need first of all
Well, the situation is like this: D creates a list of names of files
that should be loaded by C. C then takes the list, uses it to load the
files, then stores both the pointers to the loaded files and the names
of the files in an array of structs. Then when C wants to access the
files, it asks D
object.d: Error: module object is in file 'object.d' which cannot be read
import path[0] = /etc/../../src/phobos
import path[1] = /etc/../../src/druntime/import
As you can see dmd.conf uses relative paths.
That guide needs an overhaul.
The easiest way is to copy the contents of the zip archive

I have compiled this little D2 program:
int[] foo() {
return [];
}
int[] bar() {
return null;
}
void main() {}
Using DMD 2.052, dmd -O -release -inline test2.d
This is the asm of the two functions:
_D5test23fooFZAicomdat
L0: pushEAX
mov EAX,offset
I'm in directory ~/root and I have 't1.d' in ~/root/src/core
directory, and nothing else.
I run: 'gdc -O3 -o t1 t1.d -B./src/core' but I get
gdc: t1.d: No such file or directory
gdc: no input files
I've tried different paths, but I can't get it work. What's the problem?

Hmm, if I was to do it from C, I would have to deal with all the
allocation, since I don't know how large the array is going to be when
it's complete, while D doesn't need to know since it uses dynamic
arrays.

There're examples in docs for phobos and other libraries.
Yeah, I saw them. Aren't there any other places? :)

Are you looking for example code explaining specific pieces of
functionality (e.g. Phobos), or just for applications/libraries written
in D so you can see

examples from TDPL: http://erdani.com/tdpl/code/
You could browse github and dsource. Some blogposts also contain examples,

[] is not null, it's an array of 0 elements, what is done exactly.
edx points to the allocated array.
I don't understand what you say. I think the caller of foo() and bar() receive
the same thing, two empty registers. I think that cast(int[])null and
cast(int[])[] are the same thing

Could it be you also deleted the dmd.conf in the local dmd/linux/bin?

Perhaps druntime got messed up then. Is

there? Or did you ever mess with your dmd.conf? If you're using the default

You don't have libz installed? Oh, you're running 64bit, you need

I've found the problem and the solution, see this post:
http://www.kvraudio.com/forum/viewtopic.php?p=4467686#4467686
I completely forgot that the VST standard has at least two different
implementations, v2.3 and v2.4. And I've also forgot that I need to
ask the DLL if it supports calling one of
import std.stdio;
import std.conv : to;
void main()
{
uint state = 1;
writeln( to!bool(state) );
}
D:\DMD\dmd2\windows\bin\..\..\src\phobos\std\conv.d(99): Error: template
std.conv.toImpl(T,S) if (!implicitlyConverts!(S,T) isSomeString!(T)
isInputRange!(Unqual!(S))
Wow not a minute later and I get bitten by my own solution. A C
function returned 1 for a supported feature, and -1 otherwise. And of
course -1 got converted to true, so then I had a bug in my code.
Damn silly C functions which return -1 when they should return 0.
Or damn me for not RTFM'ing.
