Default flags for gcc compiler in Eclipse

Question

I want all my C programs to be compiled with the options -Wall -pedantic -ansi by default. Is there a way to have Eclipse add these flags to the compiler comman

Answer 1

Eclipse on Windows: For a project: Properties -> C/C++ Build -> Setting than "Tool Setting" tab. select "CGG C++ Compiler" than at the right side you will see Command : g++ modify it to Command: g++ CFLAGS for instance if you like to have C++11 support modify as Command: g++ --std=c++11

PS: This modification will valid for only current project and for only current configuration. If you want it for all configurations modify each configuration (Run, Debug) similarly.
