1.1 ! root 1: #!/bin/sh ! 2: # ! 3: # NAME ! 4: # populate ! 5: # ! 6: # SYNOPSIS ! 7: # populate target-dir [ source-dir ... ] ! 8: # ! 9: # DESCRIPTION ! 10: # Adjunct script for GNU C++ to populate a directory with C++ ! 11: # compatible header files. ! 12: # ! 13: # For each header file (whose name ends in .h) which resides in one ! 14: # of the indicated source-dirs, create a corresponding file in the ! 15: # target-dir (with the same name) which looks like: ! 16: # ! 17: # #ifndef __IN_C_REGION__ ! 18: # #define __IN_C_REGION__ ! 19: # extern "C" { ! 20: # #include_next <header.h> ! 21: # } ! 22: # #undef __IN_C_REGION__ ! 23: # #else ! 24: # #include_next <header.h> ! 25: # #endif ! 26: # ! 27: # Where "header.h" is the name of the original header file in the ! 28: # source-dir. ! 29: # ! 30: # If a file with the appropriate name already exists in the target ! 31: # directory, it will not be overwritten. ! 32: # ! 33: # NOTES ! 34: # This script assumes that your native header files are already ! 35: # at least compliant with ANSI C, and that all functions declared ! 36: # therein are properly prototyped (as they must be for C++). ! 37: # ! 38: # Currently, this condition is not fully satisfied by many (if any) ! 39: # systems. On System V Release 4, most of the system header files ! 40: # do seem to be properly prototyped though, and OSF/1 also has ! 41: # prototyped header files, but some of the argument type specifica- ! 42: # tions for some function prototypes in some OSF/1 header files may ! 43: # lack `const' qualifiers in certain places where they ought to appear. ! 44: # (This is due to the fact that OSF/1 conformat to POSIX-1988 rather ! 45: # than to the newer POSIX-1990 standard.) ! 46: # ! 47: # If your system's native include files are not properly prototyped, ! 48: # that's OK. This script will still do it's normal job (in the normal ! 49: # way) but the resulting (indirect) header files will not be very useful ! 50: # for g++ programming unless (and until) somebody puts in all of the ! 51: # prototypes for all of the functions which are declared in these files. ! 52: # ! 53: # Note that in some cases, a header file with a given name may exist ! 54: # in two or more of the given source directories. That's perfectly ! 55: # alright. Only one (corresponding) header file will be placed into ! 56: # the target directory for each such group of kindred source files. ! 57: # ! 58: # This script should probably be invoked from the GCC Makefile, via: ! 59: # ! 60: # populate $(libdir)/g++-include $(libsubdir)/include /usr/include ! 61: # ! 62: # That would insure the creation of a C++ compatible set of headers ! 63: # (in the sepcial g++-include directory) corresponding to all of the ! 64: # normal GCC header files and all of the native system's header files. ! 65: # ! 66: # AUTHOR ! 67: # Ron Guilmette ([email protected]) ! 68: # ! 69: # COPYRIGHT ! 70: # This file is part of GNU CC. ! 71: # ! 72: # GNU CC is free software; you can redistribute it and/or modify ! 73: # it under the terms of the GNU General Public License as published by ! 74: # the Free Software Foundation; either version 2, or (at your option) ! 75: # any later version. ! 76: # ! 77: # GNU CC is distributed in the hope that it will be useful, ! 78: # but WITHOUT ANY WARRANTY; without even the implied warranty of ! 79: # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
