Read up on name mangling.
The problem is that the symbols you have in libtar.a are "plain-C"
unmangled symbols, but the symbols you need are C++-mangled ones.

In C++ code, don't do this:

  extern int tar_extract_all(TAR*, char*);

do this instead:

  extern "C" int tar_extract_all(TAR*, char*);

If you are not prototyping these symbols yourself, but include a
header with prototypes, then the bug is in that header (it's not
C++-compatible). The fix:

extern "C" {
  #include "tar.h"
}
