The 2 powerpc (non-64) build attempts for clang 3.6 did not get this = problem. So this specific problem is powerpc64 specific. Bootstrapping powerpc (non-64) clang 3.6 via gcc 4.8.4 (the current = lang/gcc) works fine. (In absence of any c++ port lang/clang36 = automatically installed lang/gcc (currently gcc 4.8.4) in order to = bootstrap itself.) Bootstrapping powerpc (non-64) clang 3.6 via gcc5 (by having lang/gcc5 = already installed first) still reports an error for not declaring = ::sscanf, just like powerpc64 based on gcc5 for bootstrapping did. (This might be llvm/clang making use of only <cstdio> where an include = of <stdio.h> would be required to be involved in order to guarantee the = :: (global) declaration/definition. The way the C++ standard (all = vintages) is written gcc 4.8.4 and gcc5 could be this different and both = be valid/conforming.) =3D=3D=3D Mark Millard markmi at dsl-only.net On 2015-Mar-16, at 05:04 PM, Mark Millard <markmi at dsl-only.net> = wrote: Basic context (more context details listed later): # freebsd-version -ku; uname -ap 11.0-CURRENT 11.0-CURRENT FreeBSD FBSDG5C0 11.0-CURRENT FreeBSD 11.0-CURRENT #0 r279514M: Wed Mar = 11 19:23:14 PDT 2015 = root@FBSDG4C0:/usr/obj/powerpc.powerpc64/usr/srcC/sys/GENERIC64vtsc-NODEBU= G powerpc powerpc64 The problem: portmaster -tDK --no-confirm lang/clang36 is how I started the build. The error report was after it reported entering the directory: = /usr/obj/portswork/usr/ports/lang/clang36/work/llvm-3.6.0.src/tools/clang/= lib/Driver/ The report was: llvm-build: error: invalid native target: 'powerpc64' (not in project) I'd be surprised if 11.0-CURRENT vs. 10.1-STABLE matters. But powerpc64 = likely does. I've not yet tried from a powerpc (non-64) FreeBSD build. I'll note that with top -PaSCHopid I watched it compile the PowerPc code = generator software: it shoudl be able to handle PowerPCs fine. My guess is a conversion of naming conventions is required someplace: FreeBSD using powerpc64 vs. clang using ppc64. (Big endian context.) This likely would matter for little endian naming as well (ppc64le on = the clang end of things I expect).=20 Context details: # svnlite info /usr/ports/lang/clang36 Path: lang/clang36 Working Copy Root Path: /usr/ports URL: https://svn0.us-west.freebsd.org/ports/head/lang/clang36 Relative URL: ^/head/lang/clang36 Repository Root: https://svn0.us-west.freebsd.org/ports Repository UUID: 35697150-7ecd-e111-bb59-0022644237b5 Revision: 381120 Node Kind: directory Schedule: normal Last Changed Author: brooks Last Changed Rev: 380295 Last Changed Date: 2015-03-02 12:21:38 -0800 (Mon, 02 Mar 2015) It used gcc5 to bootstrap as there was no clang present and that is the = only gcc port installed: # svnlite info /usr/ports/lang/gcc5 Path: lang/gcc5 Working Copy Root Path: /usr/ports URL: https://svn0.us-west.freebsd.org/ports/head/lang/gcc5 Relative URL: ^/head/lang/gcc5 Repository Root: https://svn0.us-west.freebsd.org/ports Repository UUID: 35697150-7ecd-e111-bb59-0022644237b5 Revision: 381120 Node Kind: directory Schedule: normal Last Changed Author: gerald Last Changed Rev: 380943 Last Changed Date: 2015-03-10 10:00:25 -0700 (Tue, 10 Mar 2015) # more /etc/make.conf #CPP=3Dclang-cpp #CC=3Dclang #CXX=3Dclang++ WRKDIRPREFIX=3D/usr/obj/portswork #WITH_DEBUG=3D MALLOC_PRODUCTION=3D =3D=3D=3D Mark Millard markmi at dsl-only.net
