 Ergo, you didn't link in tango.core.Memory, which it wants.

Thanks a lot.But may I ask...so I have to use Tango's runtime in D2 other than 
D2's runtime,or,to use both?

 Ah yes,I once translated most of Tango's tango.util.container.* into D2 
 excluding one or two modules  which heavily depends on Tango other modules.It 
 get compiled.However,the test program crashed with below error message:
 Error 42:Symbol Undefined _D5tango4core6Memory2GC6addrOfFpvZPv 
 ---errorlevel 1 
 
 I have no clue what this means and where to restart.

Greeting to everybody,

If this is too silly a question,please just ignore it.

I was wondering what if GC is turned off during the lifetime of the 
application?Just as if D is a better,safer/unsafer C with class?Can't work?Or 
some special stuff need to handle?

Thanks for your help in advance.

Hello Sam,

There are some parts of D (like AA) that allocate memory from the GC but 
for which it would be hard to impossible for the programmer to tell when 
to deallocate. If you use these features while the GC is off, you will leak 
memory untill you turn it back on (at that point the GC will clean it up). 
In some short lived programs this is no problem.



Thanks for your help in advance.
