What's happening? clang is using it's internal assembler instead of calling the system one. It chokes on the syntax. Why is it happening? There's a flag to stop it - "-no-integrated-as". This should be set in /usr/share/mk/bsd.sys.mk: ---- # We need this conditional because many places that use it # only enable it for some files with CLFAGS.$FILE+=3D${CLANG_NO_IAS}. # unconditionally, and can't easily use the CFLAGS.clang=3D # mechanism. .if ${COMPILER_TYPE} =3D=3D "clang" CLANG_NO_IAS=3D -no-integrated-as .endif ---- For some reason, on the Azure version, it isn't. I have a nasty feeling that the make code that figures out which compiler it should be using isn't actu= ally working, and COMPILER_TYPE may not be setting properly. I'll find out if it= 's worse after building the kernel, which takes AGES on Azure. Work around? You can over-ride CC --=20 You are receiving this mail because: You are the assignee for the bug.=
