/* Jim Blandy <jimb@occs.cs.oberlin.edu> - September 1992
|
|
|
|
When using GCC 2 as the linker in the build process, options
|
|
intended for the linker need to be prefixed with the "-Xlinker"
|
|
option. If an option takes an argument, we need to use -Xlinker
|
|
twice - once for the option and once for its argument. For
|
|
example, to run the linker with the options "-Bstatic" "-e"
|
|
"_start", you'd need to pass the following options to GCC:
|
|
|
|
-Xlinker -Bstatic -Xlinker -e -Xlinker _start.
|
|
|
|
The Emacs makefile used to use a Bourne Shell `for' loop to prefix
|
|
each linker option with "-Xlinker", but 1) the for loop was hairier
|
|
than one might hope because it had to work when there were no
|
|
arguments to pass to the linker - the shell barfs on a loop like
|
|
this:
|
|
|
|
for arg in ; do echo -Xlinker "$arg"; done
|
|
|
|
and 2) the whole compilation command containing this loop seems to
|
|
exit with a non-zero status and halt the build under Ultrix.
|
|
|
|
If I can't write a completely portable program to do this in C,
|
|
I'm quitting and taking up gardening. */
