Hi Boost users! Is there a way for boost.ublas to warn of type conversions with ublas::bounded_vector's? I'm using this library for scientific computations and I came across this problem, I have quite a large code so I would be useful to know if this mistake occurs elsewhere. Here is a code example: int main() { double d = M_PI; unsigned u = d; cout << "d = " << d << endl; cout << "u = " << u << endl; bounded_vector<double,3> dVec = ublas::scalar_vector<double>(3,M_PI); bounded_vector<unsigned,3> uVec = dVec; // ATTENTION: type conversion! cout << "dVec = " << dVec << endl; cout << "uVec = " << uVec << endl; return 0; } When I compile this using g++ 4.6.1: g++ -g3 -Wall -Wextra -ansi -pedantic -Wconversion -std=c++0x test.cpp -o test I get the following warnings: test.cpp: In function ‘int main()’: test.cpp:11:22: warning: conversion to ‘unsigned int’ from ‘double’ may alter its value [-Wconversion] Program output: $ ./test d = 3.14159 u = 3 dVec = [3](3.14159,3.14159,3.14159) uVec = [3](3,3,3) The compiler produced a warning for the conversion of the scalars but there was no warning for the ublas conversion, is there a way of having the compiler write a warning in that case? -Wconversion or any of the other options don't do this. Best, Matija
