While powerpc64-gcc (and so powerpc64-xtoolchain-gcc) fails to build = when portmaster'd on powerpc64 it does build on powerpc. So I portmaster'd powerpc64-xtoolchain-gcc in the powerpc (non-64) = 11.0-CURRENT context to attempt a "cross" compile back to powerpc... The problem: (Or is the below attempt a form of abuse of powerpc64-xtoolchain-gcc?) (Remember: no clang exists beforehand.) For... make CROSS_TOOLCHAIN=3Dpowerpc64-gcc toolchain KERNCONF=3DGENERICvtsc = TARGET=3Dpowerpc TARGET_ARCH=3Dpowerpc or make CROSS_TOOLCHAIN=3Dpowerpc64-gcc buildworld buildkernel = KERNCONF=3DGENERICvtsc TARGET=3Dpowerpc TARGET_ARCH=3Dpowerpc Either way the result fails to complete by attempting to use = clang-tblgen when it does not exist (yet?): > ... > -------------------------------------------------------------- > >>> stage 1.2: bootstrap tools > -------------------------------------------------------------- > ... > =3D=3D=3D> lib/clang/libllvmx86instprinter (buildincludes) > =3D=3D=3D> lib/clang/libllvmx86utils (buildincludes) > =3D=3D=3D> lib/clang/include (buildincludes) > clang-tblgen -gen-arm-neon -d arm_neon.d -o arm_neon.h = /usr/src/lib/clang/include/../../../contrib/llvm/tools/clang/include/clang= /Basic/arm_neon.td > make[6]: exec(clang-tblgen) failed (No such file or directory) > *** Error code 1 >=20 > Stop. > make[6]: stopped in /usr/src/lib/clang/include > *** Error code 1 >=20 > Stop. > make[5]: stopped in /usr/src/lib/clang > *** Error code 1 >=20 > Stop. > make[4]: stopped in /usr/src/lib > *** Error code 1 >=20 > Stop. > make[3]: stopped in /usr/src/lib > *** Error code 1 >=20 > Stop. > make[2]: stopped in /usr/src > *** Error code 1 >=20 > Stop. > make[1]: stopped in /usr/src > *** Error code 1 >=20 > Stop. > make: stopped in /usr/src Even if overall this style of bootstrap should not work it seems odd to = me that clang-tblgen use was attempted before it was built. =3D=3D=3D Mark Millard markmi at dsl-only.net
