Hi there,
I have a problem compiling the following code
with g++ 2.95.3 and boost 1.28.0.
---%<---
#include
#include
struct A
{
A(boost::function0<void> const &) { }
};
void foo(boost::function0<void> const &) {}
void bar(unsigned int) {}
int main(int argc, char *argv[])
{
boost::bind(foo, boost::bind(bar, 0)); // ok
A a1(boost::bind(bar, 0)); // ok
A a2(boost::bind(foo, boost::bind(bar, 0))); // error
return 0;
}
--->%---
The line marked with error gives me a whole flood of
error messages. Is this a problem with my version of
gcc? Or am I doing a stupid mistake?
TIA, Markus
PS: Here are the errors I get:
