>Organization:
Alcatel Australia Limited
>Environment:
FreeBSD 5.0-CURRENT as of 3rd August (cvs-cur 6576)
incorporating GNU binutils 2.10.0 targeted to elf_i386
>Description:
When linking against a shared library that references another
shared library, if the implicitly referenced library cannot
be located, ld will report an error like:
/usr/libexec/elf/ld: warning: libfoo.so, needed by ./libbar.so, not found (try using --rpath)
There is no option `--rpath' documented in either ld.1 or ld.texinfo
and the message should refer to `-rpath' and/or `-rpath-link'.
(Note that ld parses `--rpath' the same as `-rpath', along with
other long options. I'm not sure whether this is a bug or a feature).
>How-To-Repeat:
echo 'foo() { }' > foo.c
echo 'bar() { foo(); }' > bar.c
echo 'main() { bar(); }' > main.c
cc -c -D_REENTRANT -fpic foo.c
cc -o libfoo.so -shared foo.o
cc -c -D_REENTRANT -fpic bar.c
cc -o libbar.so -shared bar.o -L. -lfoo
cc -o main main.c -L. -lbar
/usr/libexec/elf/ld: warning: libfoo.so, needed by ./libbar.so, not found (try using --rpath)
