Global compiler flags in CDT

Question

We are using the -Werror -Wextra -Wall -pedantic compiler flags, and C++11 diaelect. We want to use these for all of our projects. Currently we are setting these to each project by Project properties -> C/C++ Build -> Settings -> Tool Settings -> GCC C++ Compiler .

But this is a project-level setting.

I read lots of questions, i tried lots of things, but i did not found a working solution for setting the flags globally. Is there a way to do this? I am using the latest Eclipse (4.4 Luna), and the latest CDT (8.4).

Answer 1

I am also using eclipse luna.

In top menu : Window -> Preferences -> C/C++ -> Build -> Settings

Select Discovery tab, and change the CDT GCC Built-in settings (if you use gcc).

Default is like :

${COMMAND} -E -P -v -dD "${INPUTS}"

change to

${COMMAND} -E -P -v -dD "${INPUTS}" -Werror -Wextra -Wall -pedantic
