What's your favorite g++ option? [closed]

Question

I am a newbie in C++ programming. When compiling I never use any option.

This is my day to day command:

g++ MyCode.cc -o MyCode

For safety practice what's the best option to use?

Answer 1

Actually, it's a set: -Wall -pedantic -std=c++98

Answer 2

g++ -W -Wall -Werror

Will display all errors and warnings possible and treat them as errors.

Answer 3

g++ -Wall -Weffc++ -Werror -pedantic

When I'm using Boost, though, I drop it down to:

g++ -Wall -Werror

I'm anxiously awaiting GCC 4.4 and 4.5, though. There are some features coming that I really badly need.

Answer 4

I like -march=athlon -O2 -pipe for building most programs (I run Gentoo at home), and I use -ansi -pedantic -Wall for code I write myself.

Answer 5

g++ -g 

I really need that debug information....

Answer 6

If you thought you caught everything, try -Wextra
