That won't do good unless you also remove the argument to -soname, i.e.,
remove -Wl,  Could you please try merging this, i.e.,
instead of 
  -Wl,-soname -Wl,


and also add -v to see whether gcc happens to reorder arguments for ld?

Just to be sure: the .libs directory does exist, no?

Typically that's because you need to add -no-undefined.
