how can I change build configuration to Release for Blinkly example in eclipse IDE.

[saiteja]

I have a downloaded blinkly project for nRF51 build it and flashed the code on PCA10028 board. Added my own custom library to project to accomplish a feature (For which I had to change Makefile), Every thing works till now. The only problem is the binary size is quite high, the reason I infer is Blinkly project being in a Default configuration while compiling the project.

How can I change the build configuration from Default mode to Release mode? In other words the question is How do I reduce my Binary size, what compiler options should I be concentrating on? Any help is appreciated.

I thought that the flags in the Makefile

CFLAGS += -Wall -Werror -O3 -g3

make sure that the compiler uses maximum optimizations possible, in other words, it should be equivalent to release mode.

When you are adding new project to eclipse, it does give you an option to select debug or release. Not sure how the underlying implications of this are.
