How to add EXTRA_CFLAGS to indigo eclipse cdt?

  • 772

I used the instructions here to install eclipse and the here to create an eclipse project but I suspect the instructions were written for an older version of eclipse. Specifically, there is no Build (Incremental Build): build install EXTRA_CFLAGS+=-g... in this version of eclipse. I have created the project without the EXTRA_CFLAGS and have been poking around in it looking for a place to add or set them. I see a number of things that look close in Project Properties but nothing that seems like a match.

10.04 eclipse eclipse-cdt

    It's not all one line item in eclipse...looking at your link it wants you to do something like this:

    gcc -g EXTRA_CFLAGS+=-O0 EXTRA_CFLAGS+=-fno-omit-frame-pointer
    Let's take that apart: -g Default debug level so
    Project Properties->C/C++ Build->Settings->Tool Settings->Debugging and select Debug Level Default (-g)
    enter image description here
    -O0 Optimization level so
    Same tab Optimization None(-O0)
    enter image description here
    -fno-omit-frame-pointer so
    Same tab Miscellaneous Other flags add -fno-omit-frame-pointer enter image description here
    You may or may not want to remove the other flags, but I wouldn't.
    So you check in gcc c compiler and it looks like this
    enter image description here
    Apply and OK.
    Repeat the same(disabling debug completely) for your release build. Done and done.
