Enum problem:
/usr/local/include/ev++.h:79: error: comma at end of enumerator list
That is the single case where we indeed rely on the next c++ standard,
and g++ (and most other compilers) support it, so this is your
problem to
deal with. I won't change correct code because you think you have to
use
compiler switches that are not recommended by the compiler vendor.
Ok. I can't build own C++ project with libev on FreeBSD 7.2 (gcc
4.2.1), because enum contains last comma.
It so is critical to leave the comma?
Warnings generated by -Wextra:
Please read the libev documentation regarding this first.
EV_P_ is "struct ev_loop *loop,". And it generates warning of unused
loop variable.
That's a problem with your compiler (more specifically your
settings) -
the code is valid C++.
If that is indeed a real problem for you, then you are the only one
who
cna fix it, as the problem is outside of libev's code.
I don't understand... The header ev++.h generates warnings and errors
(standard gcc in FreeBSD 7.2). Is it my problem? :-) Do you support
this OS?
Prototype of IOEventManager::Cleanup is "void
(*IOEventManager::Cleanup)()";
That is not part of libev. Since ev++.h works with a lot of toher
packages, this is most likely a bug in your program - see for example
rxvt-unicode for actual uses of ev++.h that are correct.
Example code:
--snip--
#include <ev++.h>
#include <iostream>
const double kTimeout = 1.0;
class Timer {
public:
Timer() {
timer.set<Timer, &Timer::TimerCallback>(this);
timer.set(0., kTimeout);
timer.again();
}
private:
void TimerCallback() {
std::cerr << "Timer works!" << std::endl;
}
ev::timer timer;
};
int main(int argc, char **argv) {
Timer a;
ev::default_loop loop;
loop.loop();
return 0;
}
