2006-09-27 Chapter 4. GCC Command Options When you invoke GCC, it normally does preprocessing, compilation, assembly and linking. The "overall options" allow you to stop this process at an intermediate stage. For example, the -c option says not to run the linker. Then the output consists of … The option -fgnu89-inline tells GCC to use the traditional GNU semantics for inline functions when in C99 mode. Using this option is roughly equivalent to adding the gnu_inline function attribute to all inline functions. This option is accepted by GCC versions 4.1.3 and up.

This option should always be used, in order to generate better code. To compile a file without linking it, use the -c option: g++ -o file.o -Wall -c file.cpp This produces an object file named file.o which can later be linked with other files to produce a binary: g++ -o app file.o otherfile.o More about optimization options can be found at gcc.gnu.org. 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.

However, while I can find lots of information using e.g. --help=common and --help=separate, I can't find any section describing -L and -l for specifying libraries. Since -L and -l have been critical for application development for many years, they must be present in some help section. 2017-04-06 GCC was originally written as the compiler for the GNU operating system. The GNU system was developed to be 100% free software, free in the sense that it respects the user's freedom .
