NAME
cc - front-end to the C compilerSYNOPSIS
[-cEgkLMPOStvXx [-fPIC ] ] [-fpic ] [-m option ] [-nostartfiles ] [-nostdinc ] [-nostdlib ] [-pg ] [-pthread ] [-static ] [-B prefix ] [-D macro[=value] ] [-d option ] [-I directory ] [-include path ] [-isystem path ] [-o outfile ] [-Wl flags ] [file ... ]DESCRIPTION
The utility provides a front-end to the ``portable C compiler'' Multiple files may be given on the command line. Unrecognized options are all sent directly to ld(1).Filenames that end with .c are passed via cpp(1) -> ccom(1) -> as(1) -> ld(1).
Filenames that end with .i are passed via ccom(1) -> as(1) -> ld(1).
Filenames that end with .s are passed via as(1) -> ld(1).
Filenames that end with .S are passed via cpp(1) -> as(1) -> ld(1).
Filenames that end with .o are passed directly to ld(1).
The options are as follows:
- -B prefix
- Define alternate prefix path for cpp(1), ccom(1), as(1), or ld(1) executables.
- -C
- Passed to the cpp(1) preprocessor to not discard comments.
- -c
- Only compile or assemble and then stop. Do not link. The resulting object output is saved as a filename with a ``.o'' suffix unless -o option is used. Note: cannot be combined with -o if multiple files are given.
- -D macro[=value]
- Passed to the cpp(1) preprocessor to define macro
- -d option
- Passed to the as(1) assembler.
- -E
- Stop after preprocessing with cpp(1). Do not compile, assemble, or link. Output is sent to standard output unless the -o option is used.
- -fPIC
- Generate PIC code.
- -fpic
- Tells C compiler to generate PIC code and tells assembler that PIC code has been generated.
- -g
- Send -g flag to ccom(1) to create debug output. This unsets the -O option.
- -I path
- Passed to the cpp(1) preprocessor to add header search directory to override system defaults.
- -include file
- Tells the cpp(1) preprocessor to include the file during preprocessing.
- -isystem path
- Defines path as a system header directory for the cpp(1) preprocessor.
- -k
- Generate PIC code. See -fpic option.
- -L
- TODO
- -M
- Pass -M flag to cpp(1) to generate dependencies for make(1).
- -m options
- Target-dependent option.
- ARM
- -mlittle-endian -mbig-endian -mfpe=fpa -mfpe=vpf -msoft-float -march=armv1 -march=armv2 -march=armv2a -march=armv3 -march=armv4 -march=armv4t -march=armv4tej -march=armv5 -march=armv6 -march=armv6t2 -march=armv6kz -march=armv6k -march=armv7
- HPPA
- i386
- MIPS
- -mlittle-endian -mbig-endian -mhard-float -msoft-float
- PDP-10
- PowerPC
- Sparc64
- VAX
- -nostartfiles
- Do not link with the system startup files (crt0.c, etc.)
- -nostdinc
- Do not use the system include paths (/usr/include, etc.)
- -nostdlib
- Do not link with the system C library (libc).
- -O
- Enable optimizations. Currently passes -xdeljumps and -xtemps to ccom(1). Note: this is unset if the -g option is used.
- -o outfile
- Save result to outfile
- -P
- TODO
- -pg
- Enable profiling on the generated executable.
- -pthread
- Defines _PTHREADS preprocessor directive for cpp(1). Uses -lpthread for the ld(1) linker.
- -S
- Stop after compilation by ccom(1). Do not assemble and do not link. The resulting assembler-language output is saved as a filename with a ``.s'' suffix unless the -o option is used. Note: cannot be combined with -o if multiple files are given.
- -static
- Do not use dynamic linkage. By default, it will link using the dynamic linker options and/or shared objects for the platform.
- -shared
- Create a shared object of the result. Tells the linker not to generate an executable.
- -t
- Passes -t to cpp(1) for traditional C preprocessor syntax.
- -U macro
- Passes to the cpp(1) preprocessor to remove the initial macro definition.
- -v
- Outputs the version of and shows what commands will be run with their command line arguments.
- -Wl flags
- Options for the linker.
- -X
- Don't remove temporary files on exit.
- -x
- May be used to give separate optimization flags to ccom, see -O for options.
- -x c
- Gcc compatibility option; specify that the language in use is c
Predefined Macros
A few macros are predefined by when sent to cpp(1).- __PCC__
- Set to the major version of pcc(1). These macros can be used to select code based on pcc(1) compatibility. See the -v option.
- __PCC_MINOR__
- Set to the minor version.
- __PCC_MINORMINOR__
- Set to the minor-minor version --- the number after the minor version.
- _PTHREADS
- Defined when -pthread switch is used.
Also system- and/or machine-dependent macros may also be predefined; for example: __NetBSD__ __ELF__ and __i386__
