1.1 ! root 1: ! 2: ! 3: ranlib Definition ranlib ! 4: ! 5: ! 6: ! 7: ! 8: The ranlib is a ``directory'' that appears at the beginning of ! 9: each library. It contains the name of each global symbol (i.e., ! 10: function name) that appears within the library, and a pointer to ! 11: the module in which that symbol is defined. Thus, the ranlib ! 12: eliminates the need for the linker to search the entire library ! 13: sequentially to find a given global symbol, which speeds up ! 14: linking noticeably. ! 15: ! 16: If the date on the library file is later than that in the ranlib ! 17: header, the linker will ignore the ranlib and perform a sequen- ! 18: tial search through the library; the linker will also send the ! 19: warning message ! 20: ! 21: ! 22: Outdated ranlib ! 23: ! 24: ! 25: to the standard error device. This is done to prevent the ac- ! 26: cidental use of an outdated ranlib, which could be disastrous. ! 27: When you use the archiver ar to update a library or to create a ! 28: new library, be sure to employ the options that update the ranlib ! 29: as well as modify or create the library. ! 30: ! 31: ***** See Also ***** ! 32: ! 33: ar, date, ld, libraries, touch ! 34: ! 35: ! 36: ! 37: ! 38: ! 39: ! 40: ! 41: ! 42: ! 43: ! 44: ! 45: ! 46: ! 47: ! 48: ! 49: ! 50: ! 51: ! 52: ! 53: ! 54: ! 55: ! 56: ! 57: ! 58: ! 59: ! 60: ! 61: ! 62: ! 63: ! 64: COHERENT Lexicon Page 1 ! 65: ! 66:
