<excerpt>Hi Gennadiy, thank you for your tip ! I am still on the dark
though.


I've run c++filt:


c++filt _ZTv0_n12_NSoD0Ev

virtual thunk to std::basic_ostream<<char, std::char_traits<<char>
>::~basic_ostream()


Then I tried to run just this:

<fixed><color><param>6867,3837,2120</param>#include <<iostream></color>


<color><param>7675,0F0E,504F</param>int</color> main
(<color><param>7675,0F0E,504F</param>int</color> arc,
<color><param>7675,0F0E,504F</param>char</color>** argv)

{

	std::cout <<<< <color><param>8988,1312,1514</param>"test"</color>;

</fixed>}


... and it failed with the same error. 

However, <bold>if I remove from the project the unit test framework
files</bold>, it runs fine.


I am using libstdc++.a. I don't understand what is happening.

Why when I add the unit test framework code it doesn't find the
standard library ~basic_ostream() anymore ?


It seems these last 5 years doing only Java got me really rusty with
C++ (I'd rather work with C++ but the market forced me to go to Java).


I really appreciate your help, thanks !


Best regards,

Try to run through c++filt or something similar to demandle this symbol

I had problems with an ostream when I started using Xcode. Your
problem sounds similar, maybe not exactly the same. IIRC, the fix was
simply to turn off ZeroLink. Basically, the moral of the story was
don't use ZeroLink with C++.
