How to link math.h library in geany?

问题

SO I startedd coding with geany but every time i use the library math.h and then use somthing like pow or powf it marks me an error.

I do realize that when compiling i have to use -lm in the terminal but is there a way to make it so that geany will automatically use -lm when compiling in geany?

Thank you! c:

回答1:

Add -lm to compiler command configuration done under Build->Set Build Commands. you could also build a a makefile your file.

回答2:

You can't add the math.h to your program since it is a header file. But the functions defined in math.h are implemented in the libm.a.

You should add -lm to your compiler call to avoid this link error.
