It then optionally runs make - * on the Makefile. - * Options: - * -D define. Same as cpp -D argument. - * -U undefine. Same as cpp -U argument. - * -W warning. Same as cpp -W argument. - * -I Include directory. Same as cpp -I argument. - * -T template. Designate a template other - * than Imake.tmpl - * -f specify the Imakefile file - * -C specify the name to use instead of Imakefile.c - * -s[F] show. Show the produced makefile on the standard - * output. Make is not run is this case. If a file - * argument is provided, the output is placed there. - * -e[F] execute instead of show; optionally name Makefile F - * -v verbose. Show the make command line executed. - * - * Environment variables: - * - * IMAKEINCLUDE Include directory to use in addition to "." - * IMAKECPP Cpp to use instead of /lib/cpp - * IMAKEMAKE make program to use other than what is - * found by searching the $PATH variable. - * Other features: - * imake reads the entire cpp output into memory and then scans it - * for occurences of "@@". If it encounters them, it replaces it with - * a newline. It also trims any trailing white space on output lines - * (because make gets upset at them). This helps when cpp expands - * multi-line macros but you want them to appear on multiple lines. - * It also changes occurences of "XCOMM" to "#", to avoid problems - * with treating commands as invalid preprocessor commands. - * - * The macros MAKEFILE and MAKE are provided as macros - * to make. MAKEFILE is set to imake's makefile (not the constructed, - * preprocessed one) and MAKE is set to argv[0], i.e. the name of - * the imake program. - * - * Theory of operation: - * 1. Determine the name of the imakefile from the command line (-f) - * or from the content of the current directory (Imakefile or imakefile). - * Call this <imakefile>. This gets added to the arguments for - * make as MAKEFILE=<imakefile>. - * 2. Determine the name of the template from the command line (-T) - * or the default, Imake.tmpl. Call this <template> - * 3. Determine the name of the imakeCfile from the command line (-C) - * or the default, Imakefile.c. Call this <imakeCfile> - * 4. Store lines of input into <imakeCfile>: - * - A c-style comment header (see ImakefileCHeader below), used - * to recognize temporary files generated by imake. - * - If DEFAULT_OS_NAME is defined, format the utsname struct and - * call the result <defaultOsName>. Add: - * #define DefaultOSName <defaultOsName> - * - If DEFAULT_OS_MAJOR_REV is defined, format the utsname struct - * and call the result <defaultOsMajorVersion>. Add: - * #define DefaultOSMajorVersion <defaultOsMajorVersion> - * - If DEFAULT_OS_MINOR_REV is defined, format the utsname struct - * and call the result <defaultOsMinorVersion>. Add: - * #define DefaultOSMinorVersion <defaultOsMinorVersion> - * - If DEFAULT_OS_TEENY_REV is defined, format the utsname struct - * and call the result <defaultOsTeenyVersion>. Add: - * #define DefaultOSTeenyVersion <defaultOsTeenyVersion> - * - If DEFAULT_MACHINE_ARCITECTURE is defined, format the utsname struct - * and define the corresponding macro. (For example on the amiga, - * this will define amiga in addition to m68k). - * - If the file "localdefines" is readable in the current - * directory, print a warning message to stderr and add: - * #define IMAKE_LOCAL_DEFINES "localdefines" - * #include IMAKE_LOCAL_DEFINES - * - If the file "admindefines" is readable in the current - * directory, print a warning message to stderr and add: - * #define IMAKE_ADMIN_DEFINES "admindefines" - * #include IMAKE_ADMIN_DEFINES - * - The following lines: - * #define INCLUDE_IMAKEFILE < <imakefile> > - * #define IMAKE_TEMPLATE " <template> " - * #include IMAKE_TEMPLATE - * - If the file "adminmacros" is readable in the current - * directory, print a warning message to stderr and add: - * #define IMAKE_ADMIN_MACROS "adminmacros" - * #include IMAKE_ADMIN_MACROS - * - If the file "localmacros" is readable in the current - * directory, print a warning message to stderr and add: - * #define IMAKE_LOCAL_MACROS "localmacros" - * #include IMAKE_LOCAL_MACROS - * 5. Start up cpp and provide it with this file. - * Note that the define for INCLUDE_IMAKEFILE is intended for - * use in the template file. This implies that the imake is - * useless unless the template file contains at least the line - * #include INCLUDE_IMAKEFILE - * 6. Gather the output from cpp, and clean it up, expanding @@ to - * newlines, stripping trailing white space, cpp control lines, - * and extra blank lines, and changing XCOMM to #. This cleaned - * output is placed in a new file, default "Makefile", but can - * be specified with -s or -e options. - * 7. Optionally start up make on the resulting file. - * - * The design of the template makefile should therefore be: - * <set global macros like CFLAGS, etc.> - * <include machine dependent additions> - * #include INCLUDE_IMAKEFILE - * <add any global targets like 'clean' and long dependencies> - */ -#if defined(__FreeBSD__) || defined(__NetBSD__) || defined(__DragonFly__) -/* This needs to be before _POSIX_SOURCE gets defined */ -# include <sys/param.h> -# include <sys/types.h> -# include <sys/sysctl.h> -#endif -#include <stdlib.h> -#include <stdio.h> -#include <stdarg.h> -#include <X11/Xfuncproto.h> -#include <X11/Xosdefs.h> -#include <string.h> -#include <ctype.h> -#ifdef WIN32 -# include "Xw32defs.h" -#endif -#include <sys/types.h> -#include <fcntl.h> -#ifdef X_NOT_POSIX -# ifndef WIN32 -# include <sys/file.h> -# endif -#else -# include <unistd.h> -#endif -#ifdef ISC -# include <unistd.h> -#endif -#if defined(X_NOT_POSIX) || defined(_POSIX_SOURCE) -# include <signal.h> -#else -# define _POSIX_SOURCE -# include <signal.h> -# undef _POSIX_SOURCE -#endif -#if !defined(SIGCHLD) && defined(SIGCLD) -# define SIGCHLD SIGCLD -#endif -#include <sys/stat.h> -#ifndef X_NOT_POSIX -# ifdef _POSIX_SOURCE -# ifdef __SCO__ -# include <sys/procset.h> -# include <sys/siginfo.h> -# endif -# include <sys/wait.h> -# else -# define _POSIX_SOURCE -# include <sys/wait.h> -# undef _POSIX_SOURCE -# endif -# define waitCode(w) WEXITSTATUS(w) -# define waitSig(w) WTERMSIG(w) -typedef int waitType; -#else /* X_NOT_POSIX */ -# ifdef SYSV -# define waitCode(w) (((w) >> 8) & 0x7f) -# define waitSig(w) ((w) & 0xff) -typedef int waitType; -# else /* SYSV */ -# ifdef WIN32 -# include <process.h> -typedef int waitType; -# else -# include <sys/wait.h> -# define waitCode(w) ((w).w_T.w_Retcode) -# define waitSig(w) ((w).w_T.w_Termsig) -typedef union wait waitType; -# endif -# endif -# ifndef WIFSIGNALED -# define WIFSIGNALED(w) waitSig(w) -# endif -# ifndef WIFEXITED -# define WIFEXITED(w) waitCode(w) -# endif -#endif /* X_NOT_POSIX */ -#include <stdlib.h> -#include <errno.h> -#ifdef __minix_vmd -# define USE_FREOPEN 1 -#endif - -#ifndef WIN32 -# include <sys/utsname.h> -#else -# include <windows.h> -#endif -#ifndef SYS_NMLN -# ifdef _SYS_NMLN -# define SYS_NMLN _SYS_NMLN -# else -# define SYS_NMLN 257 -# endif -#endif -#if defined(linux) || defined(__GNU__) || defined(__GLIBC__) -# include <limits.h> -# include <stdio.h> -#endif -#ifdef __QNX__ -# include <unix.h> -#endif - -#if defined(__NetBSD__) /* see code clock in init() below */ -# include <sys/utsname.h> -#endif - -typedef unsigned char boolean; -#define TRUE 1 -#define FALSE 0 - -#include "imakemdep.h" -#ifdef CROSSCOMPILE -# include "imakemdep_cpp.h" -#endif - -#if defined CROSSCOMPILE || defined FIXUP_CPP_WHITESPACE -int InRule = FALSE; -#endif -#if defined CROSSCOMPILE || defined INLINE_SYNTAX -int InInline = 0; -#endif -#if defined CROSSCOMPILE || defined MAGIC_MAKE_VARS -int xvariable = 0; -int xvariables[10]; -#endif - -#ifndef PATH_MAX -# define PATH_MAX 1024 -#endif - -/* - * Some versions of cpp reduce all tabs in macro expansion to a single - * space.
