Command-Line Options 495 Table C.2 Continued Option Meaning Example -Olevel Optimizes the code for execution speed gcc –O3 m1.c m2.c according to the level specified by level, –o mathfuncs which can be 1, 2, or 3. If no level is specified, as in –O, then 1 is the default. Larger numbers indicate higher levels of optimization, and might result in longer compilation times and reduced debugging capability when using a debugger like gdb. -std=standard Specifies the standard for C files. 1 Use c99 gcc –std=c99 for ANSI C99 without the GNU extensions. mod1.c mod2.c -Wwarning Turns on warning messages specified by gcc –Werror warning. Useful options are all, to get mod1.c mod2.c optional warnings that might be helpful for most programs, and error, which turns all warnings into errors, thereby forcing you to correct them. 1.The current default is gnu89 for ANSI C90 plus GNU extensions.Will be changed to gnu99 (for ANSI C99 plus GNU extensions) once all C99 features are implemented.
