Project for compiling math.h under eclipse

Linux, if the program contains MATH.H, you must add LM to GCC for example: Gcc-lm-o main MAIN.C
However, compiled under Eclipse, the project automatically generates makefile, which, in any case, modifies the makefile, and is modified by eclipse in its original form at compile time.

J The problem-solving approach is as follows:

Right-key Item "Properties" > "C + + Build" > "Settings" Options > "Tool Settings" tab >

GCC cllinker option >

"Libraries" option >

Add an "M" Inside "libraries (L)"

So eclipse will generate GCC-lm parameters in the makefile it automatically survives, and when you compile the project again, the math function inside the MATH.H library will not be able to find the answer.
