Ok, that works. Thank you very much for taking the time and explaining it.

Hi,
Thanks for that answer, but I still don't think I understand. This sample test code builds with and without the -features=tmplrefstatic argument, so
I
guess I need a code example to clarify it, if you don't mind.
Thank you, -Sid Sacek
template< typename Ty > struct XYZ { static int si; static void foo( void ); XYZ( void ) { si = 555; foo(); } };
int XYZ< int >::si = 333; template<> void XYZ< int >::foo( void ) { return; }
int main( void ) { XYZ< int > xyz; }

The short answer is very simple. By default Sun C++ compiler does not allow to refer static symbols from templates. -features=tmplrefstatic turns on this ability.

To whom it may concern,
When compiling Boost code using the Sun compiler, the Boost
makes this statement.
Quote: When using this compiler on complex C++ code, such as the Boost C++
documentation library,
it is recommended to specify the following options when intializing the sun module: -library=stlport4 -features=tmplife -features=tmplrefstatic End-Quote:
I don't understand the effect of the 'tmplrefstatic' argument on the compiled code. Why is that option recommended, ie. What does it do?
I searched the web for a couple of hours for an explanation and couldn't find an answer to my question. I'm hoping somebody on this list knows because Boost is recommending it.
Thanks in advance, -Sid Sacek
