I would like to thank the Boost community for their invaluable feedback regarding the features and implementation details of Singularity. I have compiled and run Singularity on 4 different compilers: GCC 4.5, MSVC++ 2010, the Texas Instruments CL2000 compiler targeting the 2803x processor, and the Green Hills compiler targeting the Cortex-A8 ARM processor.
If I could give you a few suggestions: replace calls to throw by BOOST_THROW_EXCEPTION to allow compilation with -fno-exceptions Another suggestion would be to add support for compilers that support rvalue references but not variadic templates. Apart from that I'm afraid I don't really see the point of this against struct my_singleton { private: my_singleton() {} my_singleton(const my_singleton&); public: static my_singleton& instance() { static my_singleton ins; return ins; } }; which is simple, short, fast to compile, and thread-safe.
