If an option takes an argument, we need to use -Xlinker 27 twice - once for the option and once for its argument. For 28 example, to run the linker with the options "-Bstatic" "-e" 29 "_start", you'd need to pass the following options to GCC: 30 31 -Xlinker -Bstatic -Xlinker -e -Xlinker _start. 32 33 The Emacs makefile used to use a Bourne Shell `for' loop to prefix 34 each linker option with "-Xlinker", but 1) the for loop was hairier 35 than one might hope because it had to work when there were no 36 arguments to pass to the linker - the shell barfs on a loop like 37 this: 38 39 for arg in ; do echo -Xlinker "$arg"; done 40 41 and 2) the whole compilation command containing this loop seems to 42 exit with a non-zero status and halt the build under Ultrix. 43 44 If I can't write a completely portable program to do this in C, 45 I'm quitting and taking up gardening. */ 46 47#ifdef HAVE_CONFIG_H 48# include <config.h> 49#endif 50 51#if STDC_HEADERS 52# include <stdlib.h> /* for proper declaration of `exit' */ 53#endif 54 55#include <stdio.h> 56 57int 58main (argc, argv) 59 int argc; 60 char **argv; 61{ 62 char *progname; 63 char *prefix; 64 65 progname = argv[0]; 66 argc--, argv++; 67 68 if (argc < 1) 69 { 70 fprintf (stderr, "Usage: %s PREFIX ARGS...\n\ 71Echo each ARG preceded by PREFIX and a space.\n", progname); 72 exit (2); 73 } 74 75 prefix = argv[0]; 76 argc--, argv++; 77 78 for (; argc > 0; argc--, argv++) 79 printf ("%s %s%c", prefix, argv[0], (argc > 1) ?
