How to change the optimization level with Eclipse + CDT + MinGW?

Question

I am writing some C code with Eclipse + CDT + MinGW.

The compilation output always shows:

Info: Internal Builder is used for build
gcc -O0 -g3 -Wall -c -fmessage-length=0 -o Math.o "..\\Math.c" 

How can I change the command line parameters such as -O0, -Wall?

(I am new to Eclipse IDE.)

Answer 1

For GCC, the setting is in project properties => C/C++ Build => Settings => GCC C Compiler => Optimization.
