Hi,
when compiling the following code
<snip>
#include
#include
int main()
{
return 0;
}
</snip>
with g++ -Wall -Wextra, a bunch of warnings are produced, see below. The
first two seem trivial to solve, but I don't know about the third.
Is there a workaround to get rid of the warnings (other than to turn of
the -Wall and -Wextra) and/or should I file a bug report?
System information:
Ubuntu 8.04, 64bit
gcc 4.2.4
boost 1.36
Regards,
Roland
PS: Here are the warnings I get:
g++ -Wall -Wextra test.cpp -c -I ~/include/
