Hello folks,
I've just wanted to try out the new release and noticed that the Thread
library was not building.
Assuming this code:
#include
int main( void )
{
return 0;
}
When compiled with -std=c++0x the compilation fails with:
In file included from
./boost/boost_1_62_0/boost/exception/detail/exception_ptr.hpp:20:0,

Compilation works if I don't use -std=c++0x.
The exact compiler version is "g++ (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3".
I'm aware that g++ 4.6.3 is not among the compilers tested for C++11,
but it is for pre-Cpp11;
I'm wondering if there is a reason for that which I might not be aware
of (any known problems?).
Best regards,
Andreas
