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).. g++ -o app -Wall main.cpp -O0 To produce an optimized executable for use in production, use one of the -O options (see

Do you know the -Wall option that you use for generating warnings doesn't cover some specific warnings? There are many command line gcc options that are

Options for Debugging Your Program or GCC GCC has various special options that are used for debugging either your program or GCC:-g. Produce debugging information in the operating system's native format (stabs, COFF, XCOFF, or DWARF 2). GDB can work with this debugging information.

gcc -I adds include directory of header files. Syntax $ gcc -Idir [options] [source files] [object files] [-o output file] Example. gcc -L / -l option flags.

GCC offers a host of options, some even for the AMD-K62 processor. The common syntax is gcc [option] [filename]. All options listed below are case sensitive. The option -v differs completely from -V . Also options may be put together in pairs. So, -vc is different from -v -c.
