Package: binutils-gold
Version: 2.19.1-1
Severity: normal
See this simple example (with the old GNU ld):
$ cat a.c
#include <stdio.h>
void hello(void)
{
printf("hello\n");
}
$ cat b.c
void hello(void);
void say_hello(void)
{
hello();
}
$ cat c.c
void say_hello(void);
int main()
{
say_hello();
return 0;
}
$ gcc -fPIC -shared -o liba.so a.c
$ gcc -fPIC -shared -L. -la -o liba.so a.c
$ LD_LIBRARY_PATH=. gcc -lb -L. -o c c.c
$ LD_LIBRARY_PATH=. ./c
hello
Now when using gold, it fails to link the "c" program because it can't find the
reference to 'hello', found in liba.so:
$ gcc -fPIC -shared -o liba.so a.c
$ gcc -fPIC -shared -L. -la -o liba.so a.c
$ LD_LIBRARY_PATH=. gcc -lb -L. -o c c.c
/usr/bin/ld: ./libb.so: undefined reference to 'hello'
collect2: ld returned 1 exit status
Thanks.
