ld fails when -L/lib is on the command line

ld fails when -L/lib is on the command line

[Nathan Thern]

A complicated project I'm building fails on this call to gcc:
gcc -shared <object files> -L<lib_path_in_build_tree> -L/lib
-L/usr/lib <build_libs> <std_libs> -o .libs/cyg<lib>.dll
-Wl,--enable-auto-image-base -Xlinker --out-implib -Xlinker
.libs/lib<lib>.dll.a

If I remove the -L/lib, the call succeeds. Using the -v option to gcc,
I see that it's actually a call to
/usr/lib/gcc/i686-pc-cygwin/4.3.4/collect2.exe (which claims to be
ld.exe) that fails. Unfortunately, the gcc command is actually called
from "libtool --mode=install", so can't see any way to expunge the
offending -L/lib. How do I get this build to succeed?

regards,
NT

P.S. Also, is this a bug in the gcc-4.3.4 linker, or is it some other problem?

You're going to have to clue us in on what "fails" means in this context.

In other words, we need the error message.

Check the makefile. My suspicion is that there is a
-L$(SOME_VARIABLE)/lib there, but the variable is not defined and so
it's expanded to empty.
