Hello!
I'm using dCode IDE for compiling the Exemple in Pop3Client.d

I have this error:

but i dont understant why POPConnection provocate this error.

Before this, my question is: how can i understand this error string
"_D5tango3net4pop310Pop3Client14POP3Connection7__ClassZ" for example.
I think "tango...net...pop3..." rapresent the hierarchy folders, but
"_D.....3......4......14......7__ClassZ"???????

Thank you

It's the mangled version of 
"tango.net.pop3.Pop3Client.POP3Connection.__Class". In other words, the 
ClassInfo data[1] for the class POP3Connection in module 
tango.net.pop3.Pop3Client.
(Phobos' std/demangle.d contains an example on how to use it to 
automatically demangle such names)

The other string means class "tango.net.pop3.Pop3Client.POP3Connection 
tango.net.pop3.Pop3Client.POP3Connection._ctor(char[], char[], char[], 
int, <this-ptr>)", i.e. the constructor taking three char[]s and an int 
(and an implicit this pointer) for that same class.

Are you sure you compiled and linked the tango.net.pop3.Pop3Client module?
(A note for others who couldn't find that module: the Pop3Client module 
seems to only be available under trunk/patches/proposals in the SVN 
repository)

If the above doesn't help:
What version of Tango are you using and what version of DMD?
AFAIK Tango hasn't yet been updated for DMD v1.010. I'm not sure if it 
needs to be, but I haven't tried it either.

"Are you sure you compiled and linked the tango.net.pop3.Pop3Client module?"

In my test-program i have "import tango.net.pop3.Pop3Client;" and in Pop3Client
ther is the POP3Connection class (this class extends Telnet)



List step-by-step of my installation (Windows):

1)dmc.zip & dmd.zip ==extract==> result:C:\dm
                                                             C:\dmd

  Version: Digital Mars D Compiler v1.010

  (source: http://www.prowiki.org/wiki4d/wiki.cgi?EvaluationGuide#Installation)

2)C:\dmd\bin & C:\dm\bin added to path.


=====>Now the D compiler work with Phobos
      then...

3)Now for the installation of Tango i've tried 2 way:

   3.1) The "Automated Windows Installer"
        
        Just download the installer and launch.
        With this way the installation create a tango's folder in C:\dmd\
        Now in "MyPrograms" ther is Tango with "Switch to Tango" and "Switch to
Phobos" tools.

   3.2) The "Step By Step" (I've tried this way finally)
        
        Download the zip archive from
http://www.dsource.org/projects/tango/browser/trunk
        and extract into C:\dmd\import\tango
        result: C:\dmd\import\tango\doc
                                   \example
                                   \install
                                   \lib
                                   \patches\proposal (here we fond the
Pop3Client.d)
                                   \std
                                   \tango
        
        
        then i copy this in sc.ini:

        [Environment]
        ; LIB="% P%\..\lib";\dm\lib
        LIB="% P%\..\import\tango\lib;% P%\..\lib;% P%\..\..\dm\lib"
        ; DFLAGS="-I% P%\..\src\phobos"
        DFLAGS="-I% P%\..\import\tango" -version=Tango
        LINKCMD=% P%\..\..\dm\bin\link.exe

        for using Tango

        i run build-dmd.bat 

        when i run build-dmd.bat i have some errors!!!:
        it not found C:\dmd\import\tango\lib\compiler\dmd\aaA.obj
                     C:\dmd\import\tango\lib\compiler\dmd\util\console.obj
                     C:\dmd\import\tango\lib\compiler\dmd\typeinfo\ti_AC.obj
                     C:\dmd\import\tango\lib\common\tango\core\Exception.obj
                     ...and some other
        
        i run generate-usergdi32.bat

        

Now i've placed C:\dmd\import\tango\doc\patches\proposal\Pop3Client.d (and
Exception.d)
in C:\dmd\import\tango\tango\net\pop3.

Is correct if i think thet the cause of my problems is the not-corretly work ok
build-dmd.bat?

I don't know what to do with this "Error 42: Symbol Undefined
_D5tango3net4pop310Pop3Client14POP3Connection7__ClassZ"

That's not enough. You also need to explicitly compile that module and 
specify the .o file on the DMD command line (or specifying the .d file 
on the command line to compile it anew every time).
A tool like bud/build or rebuild will do this for you automatically, see 
http://dsource.org/projects/build or 
http://dsource.org/projects/dsss/wiki/Rebuild, respectively.
An alternative option would be to manually compile all the stuff that 
build-*.{bat,sh} doesn't and pack it into a library to specify on the 
command line. That may for instance be helpful with IDEs that aren't 
aware of the build tools I mentioned above.

No, I don't think that would cause this particular problem. However if 
you didn't install Tango correctly that may cause some other problems 
later on.


 I don't know what to do with this "Error 42: Symbol Undefined
_D5tango3net4pop310Pop3Client14POP3Connection7__ClassZ"


As mentioned above, I'd suggest using either bud/build or rebuild to 
compile your programs.
