Right, and this is not supported. Code linked into shared object must be compiled PIC. An .a library usually does not contain objects compiled by PIC, ld just dutifully reported back. >=20 > I'm much more confused now, since I thought the last time I compiled > that piece of software, I never got any error like that.

It might have worked by accident (because libstdc++.a objects referenced=20 during the link did not carried unsupported relocations), or, much more likely, the build system has changed and started doing stupid things. It must not link static libraries into shared objects. You should examine why it does this, and fix it. Changing compilers is just wasting a time. --M6R/iNHleSlW4Gwu Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (FreeBSD) iEYEARECAAYFAk77J+UACgkQC3+MBN1Mb4jLqACgqmZ+kfdT2b/UZ3LSXK9oQOpA siQAoPZuCMqkkDqFz90xGH3vZpBXSXTA =dv5v -----END PGP SIGNATURE----- --M6R/iNHleSlW4Gwu--
