Hmm, I don't know how to tell the build system otherwise that I don't want any shared library. It looks like NO_PIC is needed in bsd.lib.mk to force no .so to be built, though. Maybe it is easier to just build the .a file with -fPIC always? There is really no need for two .a files. -Dimitry --Apple-Mail=_03C65E7D-FA3B-40D1-A3BA-01E65777B791 Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.30 iEYEARECAAYFAlkh3cEACgkQsF6jCi4glqO19gCbBa7FodF+0tf/Kx2IAm2XWEEX hhoAn0li8bAoxt9nWmRLQN55pSGISXd4 =JCBu -----END PGP SIGNATURE----- --Apple-Mail=_03C65E7D-FA3B-40D1-A3BA-01E65777B791--
