Hi,
I found the problem, but don't know the cause or how to fix it.
First of all, my main code (project1.lpr) has just added the tree unit into
"uses", but not actually use any of it.
The problem occurs if I compile it using the Lazarus settings:
fpc -MObjFPC -Scghi -O1 -g -gl -vewnhi -Filib/x8

Hi,
"Missing -T" is not the problem, the problem is "undefined reference",
which caused fatal error.
I filed a bug report: http://bugs.freepascal.org/view.php?id=25001
I am pretty sure this is a bug, becuase while I continue to add code to my
TTree class, this problem is gone! In another word,

Is it feasible to use lnet for a simple TCP daemon on Linux, i.e. wait
for a connection on a predefined port, read as much data as is
available, repeat? And if so, what does the SerSock parameter to
Accept() represent?
I'd normally use a thread for this, but I've already got lnet's telnet

On Windows, too:
C:\>cd \backup\\\///\\\sich
C:\backup\sich>
Only the first backslash has to be (only one) backslash;
no slash allowed.

Anyway, isn't better if the children itself is generic? See my gtree

Ehm... Who says that TStringTree is available for the generic? Also not
every TTree would be a TStringTree?!
