It is called a macro processor because it allows +you to define \fImacros\fR, which are brief abbreviations for longer +constructs. +.PP +The C preprocessor is intended to be used only with C and \*(C+ source +code. In the past, it has been abused as a general text processor. It +will choke on input which does not obey C's lexical rules. For +example, apostrophes will be interpreted as the beginning of character +constants, and cause errors. Also, you cannot rely on it preserving +characteristics of the input which are not significant to C\-family +languages. If a Makefile is preprocessed, all the hard tabs will be +removed, and the Makefile will not work. +.PP +Having said that, you can often get away with using cpp on things which +are not C. Other Algol-ish programming languages are often safe +(Pascal, Ada, etc.) So is assembly, with caution. \fB\-traditional\-cpp\fR +mode preserves more white space, and is otherwise more permissive. Many +of the problems can be avoided by writing C or \*(C+ style comments +instead of native language comments, and keeping macros simple. +.PP +Wherever possible, you should use a preprocessor geared to the language +you are writing in. Modern versions of the \s-1GNU\s0 assembler have macro +facilities. Most high level programming languages have their own +conditional compilation and inclusion mechanism. If all else fails, +try a true general text processor, such as \s-1GNU\s0 M4. +.PP +C preprocessors vary in some details. This manual discusses the \s-1GNU\s0 C +preprocessor, which provides a small superset of the features of \s-1ISO\s0 +Standard C. In its default mode, the \s-1GNU\s0 C preprocessor does not do a +few things required by the standard. These are features which are +rarely, if ever, used, and may cause surprising changes to the meaning +of a program which does not expect them. To get strict \s-1ISO\s0 Standard C, +you should use the \fB\-std=c89\fR or \fB\-std=c99\fR options, depending +on which version of the standard you want. To get all the mandatory +diagnostics, you must also use \fB\-pedantic\fR. +.PP +This manual describes the behavior of the \s-1ISO\s0 preprocessor. To +minimize gratuitous differences, where the \s-1ISO\s0 preprocessor's +behavior does not conflict with traditional semantics, the +traditional preprocessor should behave the same way. The various +differences that do exist are detailed in the section \fBTraditional +Mode\fR. +.PP +For clarity, unless noted otherwise, references to \fB\s-1CPP\s0\fR in this +manual refer to \s-1GNU\s0 \s-1CPP\s0. +.SH "OPTIONS" +.IX Header "OPTIONS" +The C preprocessor expects two file names as arguments, \fIinfile\fR and +\&\fIoutfile\fR. The preprocessor reads \fIinfile\fR together with any +other files it specifies with \fB#include\fR. All the output generated +by the combined input files is written in \fIoutfile\fR. +.PP +Either \fIinfile\fR or \fIoutfile\fR may be \fB\-\fR, which as +\&\fIinfile\fR means to read from standard input and as \fIoutfile\fR +means to write to standard output. Also, if either file is omitted, it +means the same as if \fB\-\fR had been specified for that file. +.PP +Unless otherwise noted, or the option ends in \fB=\fR, all options +which take an argument may have that argument appear either immediately +after the option, or with a space between option and argument: +\&\fB\-Ifoo\fR and \fB\-I foo\fR have the same effect. +.PP +Many options have multi-letter names; therefore multiple single-letter +options may \fInot\fR be grouped: \fB\-dM\fR is very different from +\&\fB\-d\ \-M\fR. +.IP "\fB\-D\fR \fIname\fR" 4 +.IX Item "-D name" +Predefine \fIname\fR as a macro, with definition \f(CW1\fR. +.IP "\fB\-D\fR \fIname\fR\fB=\fR\fIdefinition\fR" 4 +.IX Item "-D name=definition" +The contents of \fIdefinition\fR are tokenized and processed as if +they appeared during translation phase three in a \fB#define\fR +directive. In particular, the definition will be truncated by +embedded newline characters. +.Sp +If you are invoking the preprocessor from a shell or shell-like +program you may need to use the shell's quoting syntax to protect +characters such as spaces that have a meaning in the shell syntax. +.Sp +If you wish to define a function-like macro on the command line, write +its argument list with surrounding parentheses before the equals sign +(if any). Parentheses are meaningful to most shells, so you will need +to quote the option. With \fBsh\fR and \fBcsh\fR, +\&\fB\-D'\fR\fIname\fR\fB(\fR\fIargs...\fR\fB)=\fR\fIdefinition\fR\fB'\fR works. +.Sp +\&\fB\-D\fR and \fB\-U\fR options are processed in the order they +are given on the command line. All \fB\-imacros\fR \fIfile\fR and +\&\fB\-include\fR \fIfile\fR options are processed after all +\&\fB\-D\fR and \fB\-U\fR options. +.IP "\fB\-U\fR \fIname\fR" 4 +.IX Item "-U name" +Cancel any previous definition of \fIname\fR, either built in or +provided with a \fB\-D\fR option. +.IP "\fB\-undef\fR" 4 +.IX Item "-undef" +Do not predefine any system-specific or GCC-specific macros. The +standard predefined macros remain defined. +.IP "\fB\-I\fR \fIdir\fR" 4 +.IX Item "-I dir" +Add the directory \fIdir\fR to the list of directories to be searched +for header files. +.Sp +Directories named by \fB\-I\fR are searched before the standard +system include directories. If the directory \fIdir\fR is a standard +system include directory, the option is ignored to ensure that the +default search order for system directories and the special treatment +of system headers are not defeated +\&. +.IP "\fB\-o\fR \fIfile\fR" 4 +.IX Item "-o file" +Write output to \fIfile\fR. This is the same as specifying \fIfile\fR +as the second non-option argument to \fBcpp\fR. \fBgcc\fR has a +different interpretation of a second non-option argument, so you must +use \fB\-o\fR to specify the output file. +.IP "\fB\-Wall\fR" 4 +.IX Item "-Wall" +Turns on all optional warnings which are desirable for normal code. +At present this is \fB\-Wcomment\fR, \fB\-Wtrigraphs\fR, +\&\fB\-Wmultichar\fR and a warning about integer promotion causing a +change of sign in \f(CW\*(C`#if\*(C'\fR expressions. Note that many of the +preprocessor's warnings are on by default and have no options to +control them. +.IP "\fB\-Wcomment\fR" 4 +.IX Item "-Wcomment" +.PD 0 +.IP "\fB\-Wcomments\fR" 4 +.IX Item "-Wcomments" +.PD +Warn whenever a comment-start sequence \fB/*\fR appears in a \fB/*\fR +comment, or whenever a backslash-newline appears in a \fB//\fR comment. +(Both forms have the same effect.) +.IP "\fB\-Wtrigraphs\fR" 4 +.IX Item "-Wtrigraphs" +Most trigraphs in comments cannot affect the meaning of the program. +However, a trigraph that would form an escaped newline (\fB??/\fR at +the end of a line) can, by changing where the comment begins or ends. +Therefore, only trigraphs that would form escaped newlines produce +warnings inside a comment. +.Sp +This option is implied by \fB\-Wall\fR. If \fB\-Wall\fR is not +given, this option is still enabled unless trigraphs are enabled. To +get trigraph conversion without warnings, but get the other +\&\fB\-Wall\fR warnings, use \fB\-trigraphs \-Wall \-Wno\-trigraphs\fR. +.IP "\fB\-Wtraditional\fR" 4 +.IX Item "-Wtraditional" +Warn about certain constructs that behave differently in traditional and +\&\s-1ISO\s0 C. Also warn about \s-1ISO\s0 C constructs that have no traditional C +equivalent, and problematic constructs which should be avoided. +.IP "\fB\-Wimport\fR" 4 +.IX Item "-Wimport" +Warn the first time \fB#import\fR is used. +.IP "\fB\-Wundef\fR" 4 +.IX Item "-Wundef" +Warn whenever an identifier which is not a macro is encountered in an +\&\fB#if\fR directive, outside of \fBdefined\fR. Such identifiers are +replaced with zero. +.IP "\fB\-Wunused\-macros\fR" 4 +.IX Item "-Wunused-macros" +Warn about macros defined in the main file that are unused. A macro +is \fIused\fR if it is expanded or tested for existence at least once. +The preprocessor will also warn if the macro has not been used at the +time it is redefined or undefined. +.Sp +Built-in macros, macros defined on the command line, and macros +defined in include files are not warned about. +.Sp +\&\fINote:\fR If a macro is actually used, but only used in skipped +conditional blocks, then \s-1CPP\s0 will report it as unused. To avoid the +warning in such a case, you might improve the scope of the macro's +definition by, for example, moving it into the first skipped block. +Alternatively, you could provide a dummy use with something like: +.Sp +.Vb 2 +\& #if defined the_macro_causing_the_warning +\& #endif +.Ve +.IP "\fB\-Wendif\-labels\fR" 4 +.IX Item "-Wendif-labels" +Warn whenever an \fB#else\fR or an \fB#endif\fR are followed by text. +This usually happens in code of the form +.Sp +.Vb 5 +\& #if FOO +\& ... +\& #else FOO +\& ... +\& #endif FOO +.Ve +.Sp +The second and third \f(CW\*(C`FOO\*(C'\fR should be in comments, but often are not +in older programs. This warning is on by default. +.IP "\fB\-Werror\fR" 4 +.IX Item "-Werror" +Make all warnings into hard errors. Source code which triggers warnings +will be rejected. +.IP "\fB\-Wsystem\-headers\fR" 4 +.IX Item "-Wsystem-headers" +Issue warnings for code in system headers. These are normally unhelpful +in finding bugs in your own code, therefore suppressed. If you are +responsible for the system library, you may want to see them. +.IP "\fB\-w\fR" 4 +.IX Item "-w" +Suppress all warnings, including those which \s-1GNU\s0 \s-1CPP\s0 issues by default. +.IP "\fB\-pedantic\fR" 4 +.IX Item "-pedantic" +Issue all the mandatory diagnostics listed in the C standard. Some of +them are left out by default, since they trigger frequently on harmless +code. +.IP "\fB\-pedantic\-errors\fR" 4 +.IX Item "-pedantic-errors" +Issue all the mandatory diagnostics, and make all mandatory diagnostics +into errors. This includes mandatory diagnostics that \s-1GCC\s0 issues +without \fB\-pedantic\fR but treats as warnings. +.IP "\fB\-M\fR" 4 +.IX Item "-M" +Instead of outputting the result of preprocessing, output a rule +suitable for \fBmake\fR describing the dependencies of the main +source file. The preprocessor outputs one \fBmake\fR rule containing +the object file name for that source file, a colon, and the names of all +the included files, including those coming from \fB\-include\fR or +\&\fB\-imacros\fR command line options. +.Sp +Unless specified explicitly (with \fB\-MT\fR or \fB\-MQ\fR), the +object file name consists of the basename of the source file with any +suffix replaced with object file suffix. If there are many included +files then the rule is split into several lines using \fB\e\fR\-newline. +The rule has no commands. +.Sp +This option does not suppress the preprocessor's debug output, such as +\&\fB\-dM\fR. To avoid mixing such debug output with the dependency +rules you should explicitly specify the dependency output file with +\&\fB\-MF\fR, or use an environment variable like +\&\fB\s-1DEPENDENCIES_OUTPUT\s0\fR. Debug output +will still be sent to the regular output stream as normal. +.Sp +Passing \fB\-M\fR to the driver implies \fB\-E\fR, and suppresses +warnings with an implicit \fB\-w\fR. +.IP "\fB\-MM\fR" 4 +.IX Item "-MM" +Like \fB\-M\fR but do not mention header files that are found in +system header directories, nor header files that are included, +directly or indirectly, from such a header. +.Sp +This implies that the choice of angle brackets or double quotes in an +\&\fB#include\fR directive does not in itself determine whether that +header will appear in \fB\-MM\fR dependency output. This is a +slight change in semantics from \s-1GCC\s0 versions 3.0 and earlier. +.IP "\fB\-MF\fR \fIfile\fR" 4 +.IX Item "-MF file" +When used with \fB\-M\fR or \fB\-MM\fR, specifies a +file to write the dependencies to. If no \fB\-MF\fR switch is given +the preprocessor sends the rules to the same place it would have sent +preprocessed output. +.Sp +When used with the driver options \fB\-MD\fR or \fB\-MMD\fR, +\&\fB\-MF\fR overrides the default dependency output file. +.IP "\fB\-MG\fR" 4 +.IX Item "-MG" +In conjunction with an option such as \fB\-M\fR requesting +dependency generation, \fB\-MG\fR assumes missing header files are +generated files and adds them to the dependency list without raising +an error. The dependency filename is taken directly from the +\&\f(CW\*(C`#include\*(C'\fR directive without prepending any path. \fB\-MG\fR +also suppresses preprocessed output, as a missing header file renders +this useless. +.Sp +This feature is used in automatic updating of makefiles. +.IP "\fB\-MP\fR" 4 +.IX Item "-MP" +This option instructs \s-1CPP\s0 to add a phony target for each dependency +other than the main file, causing each to depend on nothing. These +dummy rules work around errors \fBmake\fR gives if you remove header +files without updating the \fIMakefile\fR to match. +.Sp +This is typical output: +.Sp +.Vb 1 +\& test.o: test.c test.h +.Ve +.Sp +.Vb 1 +\& test.h: +.Ve +.IP "\fB\-MT\fR \fItarget\fR" 4 +.IX Item "-MT target" +Change the target of the rule emitted by dependency generation. By +default \s-1CPP\s0 takes the name of the main input file, including any path, +deletes any file suffix such as \fB.c\fR, and appends the platform's +usual object suffix. The result is the target. +.Sp +An \fB\-MT\fR option will set the target to be exactly the string you +specify. If you want multiple targets, you can specify them as a single +argument to \fB\-MT\fR, or use multiple \fB\-MT\fR options. +.Sp +For example, \fB\-MT\ '$(objpfx)foo.o'\fR might give +.Sp +.Vb 1 +\& $(objpfx)foo.o: foo.c +.Ve +.IP "\fB\-MQ\fR \fItarget\fR" 4 +.IX Item "-MQ target" +Same as \fB\-MT\fR, but it quotes any characters which are special to +Make. \fB\-MQ\ '$(objpfx)foo.o'\fR gives +.Sp +.Vb 1 +\& $$(objpfx)foo.o: foo.c +.Ve +.Sp +The default target is automatically quoted, as if it were given with +\&\fB\-MQ\fR. +.IP "\fB\-MD\fR" 4 +.IX Item "-MD" +\&\fB\-MD\fR is equivalent to \fB\-M \-MF\fR \fIfile\fR, except that +\&\fB\-E\fR is not implied. The driver determines \fIfile\fR based on +whether an \fB\-o\fR option is given. If it is, the driver uses its +argument but with a suffix of \fI.d\fR, otherwise it take the +basename of the input file and applies a \fI.d\fR suffix. +.Sp +If \fB\-MD\fR is used in conjunction with \fB\-E\fR, any +\&\fB\-o\fR switch is understood to specify the dependency output file, but if used without \fB\-E\fR, each \fB\-o\fR +is understood to specify a target object file. +.Sp +Since \fB\-E\fR is not implied, \fB\-MD\fR can be used to generate +a dependency output file as a side-effect of the compilation process. +.IP "\fB\-MMD\fR" 4 +.IX Item "-MMD" +Like \fB\-MD\fR except mention only user header files, not system +header files. +.IP "\fB\-x c\fR" 4 +.IX Item "-x c" +.PD 0 +.IP "\fB\-x c++\fR" 4 +.IX Item "-x c++" +.IP "\fB\-x assembler-with-cpp\fR" 4 +.IX Item "-x assembler-with-cpp" +.PD +Specify the source language: C, \*(C+, or assembly. This has nothing +to do with standards conformance or extensions; it merely selects which +base syntax to expect. If you give none of these options, cpp will +deduce the language from the extension of the source file: \&\fB.c\fR, +\fB.cc\fR, or \fB.S\fR.

As with +\&\fB\-fexec\-charset\fR, \fIcharset\fR can be any encoding supported +by the system's \f(CW\*(C`iconv\*(C'\fR library routine; however, you will have +problems with encodings that do not fit exactly in \f(CW\*(C`wchar_t\*(C'\fR. +.IP "\fB\-finput\-charset=\fR\fIcharset\fR" 4 +.IX Item "-finput-charset=charset" +Set the input character set, used for translation from the character +set of the input file to the source character set used by \s-1GCC\s0. If the +locale does not specify, or \s-1GCC\s0 cannot get this information from the +locale, the default is \s-1UTF\-8\s0. This can be overridden by either the locale +or this command line option.
