This turns off certain features of GCC that are incompatible with ISO C89, such as the asm and typeof keywords, and some predefined macros that identify the type of system you are using. GCC enables this option by default. If you want to force the compiler to check if a variable is referenced, regardless of whether or not optimization is turned on, use the -fno-keep-static-consts option. -fmerge-constants.

So, -vc is different from -v -c. Example. Assuming a single source file named main.cpp, the command to compile and link an non-optimized executable is as follows (Compiling without optimization is useful for initial development and debugging, although -Og is officially recommended for newer GCC versions)..

The gcc program accepts options and file names as operands. Many options have multi-letter names; therefore multiple single-letter options may not be grouped: -dv is very different from -d -v. You can mix options and other arguments. For the most part, the

Not all systems support this option. For predictable results, you must also specify the same set of options used for compilation (-fpic, -fPIC, or model suboptions) when you specify this linker option. As per Difference between -shared and -Wl,-shared of the GCC options Passing -shared to GCC may enable or disable other flags at link time.

gcc -Wall enables all compiler's warning messages. This option should always be used, in order to generate better code.

Option Index. GCC’s command line options are indexed here without any initial ‘-’ or ‘--’.Where an option has both positive and negative forms (such as -foption and -fno-option), relevant entries in the manual are indexed under the most appropriate form; it may sometimes be useful to look up both forms. If the -v option is also specified then --help is also passed on to the various processes invoked by gcc, so that they can display the command-line options they accept. If the -Wextra option has also been specified (prior to the --help option), then command-line options that have no documentation associated with them are also displayed. 15 Most Frequently Used GCC Compiler Command Line Options 1.
