<pre>libtool has some rather fragile code to check the linker in use, based on the
output from -v:
# Check to see if the program is GNU ld. I'd rather use --version,
# but apparently some variants of GNU ld only accept -v.
# Break only if it was the GNU/non-GNU ld that we prefer.
case `"$lt_cv_path_LD" -v 2>&1 </dev/null` in
ld.bfd -v and ld.gold -v (with no other args) reports the version and then
exits:
% ld.bfd -v
GNU ld 2.17.50 [FreeBSD] 2007-07-03
ld.lld emits an error:
% build-nodebug/bin/ld.lld -v
LLD 4.0.0 (<a href="http://llvm.org/git/lld">http://llvm.org/git/lld</a> 6a0a1412fb7e571c8d7843ab7ecf802291bff4c5)
build-nodebug/bin/ld.lld: error: no input files
build-nodebug/bin/ld.lld: error: target emulation unknown: -m or at least one
.o file required
See also the resolved PR 31057 for the same issue with the related --version
arg. With --version all three linkers (lld, bfd, gold) currently print the
version and exit, even if provided with a link command line.
With -v all three linkers print the version and then carry on with the link if
specified by remaining cmdline args:
% ld.bfd -v foo.o
ld.bfd: warning: cannot find entry symbol _start; defaulting to
0000000000400078
The only differing case is ld.lld -v with no other args.</pre>
