Eclipse C/C++ (CDT) add -l option (linking math module) gcc -lm

I am trying to have eclipse on linux (Ubuntu) link the math module. Normally I would link with gcc -lm. How do I get eclipse to add this? Is it in library paths under Project->Properties? Where does the math module reside on a linux Ubuntu system?

Solution

  • Somewhere along this path: Project->Properties->C/C++ Build->Settings, then under the Tools tab: GCC Linker->Libraries

    As for where it is in the system, usually /usr/lib/libm.so.

    FYI, this is all true of my system, but may differ slightly on yours for any number of reasons. Shouldn't be hard to adjust if needed.
