Hello,
I'm working with a team of different developers on different systems.
I'm using the g++ 4.4.5 and some colleagues the version 4.0.5. With the
same command line options, they get more warnings/errors (-Werror) than
me. The most annoying is:
warning: converting to 'int' from 'double'
How can I enable this warning in g++ 4.4.5 too? I tried -Wconversion,
but I get also warnings when converting int-to-float, which would force
me to cast each "float = float * int" statement, which is quite common.
Also many Qt headers create now warnings, which I cannot fix. So this
option is no solution for me...
Thanks a lot,
Charly
