23 | |
24 | When using GCC 2 as the linker in the build process, options | |
25 | intended for the linker need to be prefixed with the "-Xlinker" | |
26 | option. 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. */ | |
