Hi All, This is an anomaly I experienced with Portland Group C++ compiler. Well OK, Boost doesn't support this compiler... But so far for Lambda and Function libraries I was able to run all of the tests in the 1-33-1 distribution with success, and it seems pgCC is doing a real good job. There is this one exception though: pgCC generates assembly errors on this arguably weird code that I have. gcc, msvc and hpCC worked fine... So obviously this seems to be an issue for PG itself and not Boost; but the code under question is really a bit weird and I am not 100% sure if it is correct use of boost or even C++. Before I carry on with bug reports to PG I'd like to ask for your suggestions on it... Here is the code. Briefly, a boost::function is being passed to some function template that expects a functor to apply on its second argument. Another level of indirection is added where the boost::function itself is generated from a lambda expression inside another function. I wasn't able to narrow it down any further.. (highlighted code is here: http://rafb.net/p/28TknK25.html) (compiler error messages follow) // ======================================== #include <boost/function.hpp> #include <boost/lambda/lambda.hpp> #include <boost/lambda/bind.hpp> #include <boost/lambda/casts.hpp> #include <iostream> // Some struct of only double members struct A { double a; double b; }; // The "complicated" function that expect a functor to // operate on an instance of A template< class Func > void foo(const Func& f, const A& a) { std::cout << f(a) << std::endl; } // A function object generator. // It returns a functor which in turn returns some // double member of A accessed via address offset boost::function<double(const A&)> getmem ( const A* obj, const double* mem ) { ptrdiff_t shift = mem - reinterpret_cast<const double*>(obj); using namespace boost::lambda; return *(ll_reinterpret_cast<const double*>(&_1) + constant(shift) ); } // int main() { A obj; obj.a = 1.; obj.b = 2.; // foo( getmem(&obj, &obj.b), obj ); return 0; } // wherever this compiles, it prints out "2". // ========================================== Here is the compiler output: PGCC-W-0155-No va_start() seen (/opt/pgi/6.1.4/linux86-64/6.1/include/CC/iostream: 689) PGCC/x86 Linux/x86-64 6.1-4: compilation completed with warnings /tmp/pgCCbaaaasxqap.s: Assembler messages: /tmp/pgCCbaaaasxqap.s:2499: Error: junk `(%rbx)' after expression /tmp/pgCCbaaaasxqap.s:2500: Error: junk `(%rbx)' after expression The assembly lines under question is pasted here: http://rafb.net/p/LW5IX765.html -- lines 7 and 8. The va_start() warning is probably irrelevant (this is not the only place I have seen it, and never failed before with these warnings) any guidance will be appreciated, thanks -- Server Levent Yilmaz Mechanical Engineering @ PITT
