Bug ID: 17558
Summary: ld will follow DT_NEEDED when it is not necessary
Product: binutils
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: rafael.espindola at gmail dot com
$ cat test3.c
void h(void) {
}
$ cat test2.c
void h(void);
void f(void) {
h();
}
$ cat test.c
void f(void);
int main(void) {
f();
}
$ gcc test3.c -fPIC -shared -o test3.so
$ gcc test2.c -fPIC -shared -o test2.so test3.so
$ gcc test.c -o test test2.so -fuse-ld=gold
$ gcc test.c -o test test2.so -fuse-ld=bfd
/home/espindola/inst/binutils/bin/ld.bfd: warning: test3.so, needed by
test2.so, not found (try using -rpath or -rpath-link)
test2.so: undefined reference to `h'
collect2: error: ld returned 1 exit status
But test.c doesn't use h or anything from test3.so at all. All that it needs is
test2.so and that has already been created.
