eclipse cdt command line input

I'm 开发者_C百科new to eclipse cdt. I'm wondering how can i add command line argument (e.g.-lm) for compiling

Debug-> Debug-Configurations. Select Arguments

-lm include the math library. This is a linker parameters.

Project Proprerties -> C/C++ build -> Settings -> GCC Linker -> Libraries -> "add the library" m

The "correct" way is probably to include these parameters in your Makefile.

But if you're invoking the compiler manually, you should be able to set arguments by right-clicking on the project, selecting "Properties", choosing the "C/C++ Build" entry on the menu at the left, and editing the "Build command" text field.

Depending on the system you're in, you could potentially also choose the 'Build Variables' subentry under "C/C++ Build" and set them in CFLAGS/CPPFLAGS. Not every setup takes those into account, though.
