After some detective work, it looks like libstdc++ needs to be done b= efore libsupc++ is done. I=E2=80=99ve added this dependency in r268377 and = was able to do a full xdev build with a clean obj dir: >=20 > rm -rf $HOME/F $MAKEOBJDIRPREFIX/mips-freebsd > mkdir $HOME/F > make xdev DESTDIR=3D$HOME/F XDEV=3Dmips XDEV_ARCH=3Dmips WITHOUT_CLANG= =3Dt WITHOUT_CLANG_BOOTSTRAP=3Dt WITH_GCC=3Dt WITH_GCC_BOOTSTRAP=3Dt WITH_G= NUCXX=3Dt -j 20 We can avoid most of the above by using a patch like the following: http://people.freebsd.org/~bapt/Makefile.inc1.diff Extending the same thing xi-cross-tools and xb-cross-tools (expect the WITH_GNUCXX=3Dt because it it not set in src.opts.mk when it imho should.) regards, Bapt --CEUtFxTsmBsHRLs3 Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iEYEARECAAYFAlO7MsUACgkQ8kTtMUmk6EyJ8wCff7XMATfK4j4N77smru0Nl5D8 geIAoIARwHUNcwecZemz27EUiWIyH/rN =In69 -----END PGP SIGNATURE----- --CEUtFxTsmBsHRLs3--
