Assuming llvm-tblgen has already been built (it's a bootstrap-tool), and you have a regular setup, it should be in: = /usr/obj/usr/src/amd64.amd64/tmp/obj-tools/usr.bin/clang/llvm-tblgen/llvm-= tblgen You could try setting LLVM_TBLGEN to that path, then first build libllvm just to be sure, then usr.bin/clang/lld: export = LLVM_TBLGEN=3D/usr/obj/usr/src/amd64.amd64/tmp/obj-tools/usr.bin/clang/llv= m-tblgen/llvm-tblgen make -C /usr/src/lib/clang/libllvm make -C /usr/src/usr.bin/clang/lld If that works, you can run make install from usr.bin/clang/lld. -Dimitry --Apple-Mail=_EACB1B30-8690-4903-AE71-997401390EDA 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 v2.2 iF0EARECAB0WIQR6tGLSzjX8bUI5T82wXqMKLiCWowUCY/JowgAKCRCwXqMKLiCW o33SAKCctMa74JkhE+Id3cbKmfoFNDT3sgCg2slzcgTf1YN5LLsG7mjXjRKBoBM= =z8yc -----END PGP SIGNATURE----- --Apple-Mail=_EACB1B30-8690-4903-AE71-997401390EDA--
