2.2.2 File Name Conventions

The suffix attached to a file name appearing on the command line determines how the compiler processes the file. A file name with a suffix other than those listed in the following table, or without a suffix, is passed to the linker.

Table 2–1 File Name Suffixes Recognized by the C++ Compiler


Suffix	Language	Action
`.c`	C++	Compile as C++ source files, put object files in current directory; default name of object file is that of the source but with an `.o` suffix.
`.C`	C++	Same action as `.c` suffix.
`.cc`	C++	Same action as `.c` suffix.
`.cpp`	C++	Same action as `.c` suffix.
`.cxx`	C++	Same action as `.c` suffix.
`.c++`	C++	Same action as `.c` suffix.
`.i`	C++	Preprocessor output file treated as C++ source file. Same action as `.c` suffix.
`.s`	Assembler	Assemble source files using the assembler.
`.S`	Assembler	Assemble source files using both the C language preprocessor and the assembler.
`.il`	Inline expansion	Process assembly inline-template files for inline expansion. The compiler will use templates to expand inline calls to selected routines. (Inline-template files are special assembler files. See the `inline`(1) man page.)
`.o`	Object files	Pass object files through to the linker.
`.a`	Static (archive) library	Pass object library names to the linker.
`.so` .`so`.n	Dynamic (shared) library	Pass names of shared objects to the linker.
