OK... This error message has me totally confused: src/com/neuralnexus/nnengine/nodeweb.d(436): function com.neuralnexus.nnengine.nodeweb.nnWebNode.getImmediateChildren cannot access frame of function __funclit9 ???? I'm running DMD 0.113 on Linux. Thanks John

Sounds like you're trying to do something strange with a function literal. Can you show the body of nnWebNode.getImmediateChildren ? -- Chris S John Demme wrote:OK...

nnWebNode[] cRels = pcRel.getLinkedCRelChildren();
foreach(nnWebNode cRel; cRels)
foreach(nnWebNode lNode; cRel.getLinkedNodes())
if (pcRel.isLinkedTo(lNode))
ret ~= lNode;
}
if (this == nodes.Rel)
ret ~= nodes.pcRel;
return ret;
}
}
I was going to post it originally, but it's a pretty mundane function.
Also of note is that this compiled no problem with previous versions of
DMD. I haven't touched the code in awhile, so I'm not sure when it
stopped working.

Hmm... wow, now I'm confused. Don't see any use of func literals in there at all. Suddenly I see why you asked about it on the newsgroup. And is there a special reason (just something I noted when scanning it and mentally compiling) why 'nnWebNode[] ret' is defined seperately in the if and else blocks? -- Chris S

To implement the foreach, the compiler internally generates some function literals. Is it possible for you to try whacking out bits of this function to see what the minimum that triggers the error is?
Feb 14 2005
Commenting out the foreaches does nothing. What triggers it is using
nodes. This is also what's triggering my "Weird Linking Error".
With:
public struct Nodes
{
nnWebNode Root;
nnWebNode Null;
nnWebNode String;
nnWebNode Name;
nnWebNode[nnNodeID] nodes;
void init()
{// Stuff
}
}
And:
public Nodes nodes;
I get the compiler error in any function that does something like:
public nnWebNode[] getImmediateChildren()
{
nnWebNode[] ret;
if (this == nodes.Null) {}
}
And it likes that function if I change it to not use nodes.Null.
It'll also compile if I change the:
public Nodes nodes;
line to:
public static Nodes nodes;
However, when I change that line, I get the weird linking issues that
I've detailed in that post, as if the static keyword works like it does
in C when it's used in the module scope.
Is this two seperate bugs, both out to screw with my head, or two
symptoms of the same problem?

Walter,
I've got a test case for it all. With the first line commented out, it
doesn't compile. With the second line commented out, and the first
uncommented, it compiles but doesn't work. I can't get around this one.
TIA,
John
------------------------------
module test2;
//public static Nodes nodes;
public Nodes nodes;
public struct Nodes {
Object Null;
Object Name;
void init(){}
}
class A {
public int b() {
return (this == nodes.Null);
}
}
--------------------------------------
module test3;
import test2;
void main() {
nodes.init();
A a = new A();
a.b();
}

Alright.. I've got another clue, although I haven't been able to boil it down to a short test case. I've got a struct, called "Nodes" and then, first thing in the module, I've got: Nodes nodes; To create a global instance of the struct. Any function that uses this struct seems to fail on this error. Any suggestions? Please? John John Demme wrote:OK...

Hmm. Odd. A) I wouldn't think that would have to be static... but oh well, that shouldn't hurt it any at all. B) The error message sure didn't give /any/ clues at all. Obviously, considering my initial intuitive response was, "Oh, something wrong with a function literal?" I think maybe the compiler misdiagnosed. Bug. -- Chris S John Demme wrote:OK...

Strange. I wonder why the non-static version causes the "funclit" error. As for the Node struct, perhaps, without the static designation, it can't be accessed properly outside of its module; the d manual states: "Static data has only one instance for the entire program, not once per object." So what does this imply for non-static module level instances of a struct? Is access to them limited to the module only? It would be nice to know a few more nitty gritty details here about how the compiler works. -John R. John Demme wrote:OK...
