Problem with entry pointsHi, I’ve built the Math library on Windows using bjam using
this... bjam toolset=msvc --with-math --build-type=complete stage I’m using P/invoke to call functions from managed code
in C#. Generally it works fine (e.g. functions ‘beta’ and ‘ibeta’
work well) – but some of the functional entry points don’t seem to
be found (e.g. ‘ibeta_inv’). I’ve tried using dumpbin
/exports to examine the .dll but it seem to list only a subset of the total
functions. Below are a couple of the c# function definitions... This one works... [DllImport("boost_math_tr1-vc90-mt-1_40.dll",
EntryPoint = "beta", ExactSpelling
= false, CallingConvention = CallingConvention.Cdecl)] public static extern double beta(double a, double b); This one doesn’t.... [DllImport("boost_math_tr1-vc90-mt-1_40.dll",
EntryPoint = "ibeta_inv",
ExactSpelling = false, CallingConvention = CallingConvention.Cdecl)] public static extern double
ibeta_inv(double a, double
b, double p); It gives a System.EntryPointNotFoundException saying that
the entry point ‘ibeta_inv’ is not found in boost_math_tr1-vc90-mt-1_40.dll. Can anyone help ? Thanks, Charles _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost-build |

Generally it > works fine (e.g. functions 'beta' and 'ibeta' work well) - but some of the > functional entry points don't seem to be found (e.g. 'ibeta_inv'). ibeta_inv is defined like this: template <class T1, class T2, class T3, class T4, class Policy> inline typename tools::promote_args<T1, T2, T3, T4>::type ibeta_inv(T1 a, T2 b, T3 p, T4* py, const Policy& pol) So, it's not a function, it's function template and unless it's instantiated for specific types, you won't have anything to call.
