Issue
I know that these are some common/basic libraries, but what do they mean exactly?
For example, I know, that -lm is some math library, but is this the standard math library or what?
-lz for compression? What compression?
And I don't have any idea what -lrt is.
What are these things?
- math library. Is it the same that we use when we include
<cmath>or<math.h>? - compress library. What does this mean? Does it provide some tools that we can use to compress files, or does it help the compiler/linker to do some compress things?
Solution
-lz- is zlib, http://zlib.net/-lm- is the math library as you've worked out (implementation defined AFAIK)-lrt- provides POSIX realtime extensions: http://www.s-gms.ms.edus.si/cgi-bin/man-cgi?librt+3LIB
