clang-3.4 @3.4.2_6 build fails, ML on OSX

[punch@…]

I tried doing an upgrade from 3.4.2_5 to 3.4.2_6 and the build fails. This is under Mountain Lion on OSX. I ran down the make error, relevant info below. Two traces so you need to scroll down.

I can’t reproduce this with clang @3.4.2_6+analyzer+arm_runtime.

This

:info:build warning: clang_darwin.mk: dropping arch 'x86_64' from lib 'ubsan_osx'

and this

:info:build make/platform/clang_linux.mk:16: *** "unable to infer compiler target triple for /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_llvm-3.4/clang-3.4/work/llvm-3.4.2.src/Release+Debug+Asserts/bin/clang".  Stop.

make me suspect your toolchain, but I’ll wait for your log.

I cd to llvm-3.4.2.src and run /usr/bin/make -j8 -w clang-only, relevant info below

This could never have worked because the build directory was probably owned by the macports user. You wouldn’t have had permissions to correctly complete the build.

Replying to larryv@…: I added the full main.log

I'm using gcc4.7.4_3 from macports for the build. Could be the tool chain but I don't know why as I have clang3.4 and clang3.6 from macports that built less than a month ago without issue and I haven't changed anything since then.

Please run sudo port clean clang-3.4 and try upgrading again, then attach the log if that fails.

Why are you building this with GCC? We don’t really support that.

[larryv (Lawrence Velázquez)]

Replying to larryv@…:

Actually, please run

$ sudo port clean clang-3.4
$ sudo port upgrade clang-3.4 build.jobs=1

It’ll take longer, but the log will be easier to examine.

[punch@…]

main.log after clean and with build.jobs=1

[punch@…]

I did do a clean then a rebuild using build.jobs=1. New, now in fact full, version of main.log attached. Appreciate your time for looking into this

[jeremyhu (Jeremy Huddleston Sequoia)]

What are the variants for llvm-3.4 that is installed and the clang-3.4 that is installing?

[oliver.bock@…]

None for LLVM:

$ port installed llvm-3.4
The following ports are currently installed:
  llvm-3.4 @3.4_3
  llvm-3.4 @3.4.2_6 (active)

Clang 3.4 isn't installed at all (which should mean default/no variants); Clang 3.5 is the one I'm trying to update and it's triggering the Clang 3.4 build for some reason. It has the following variants enabled:

$ port installed clang-3.5
The following ports are currently installed:
  clang-3.5 @3.5-r210448_0+analyzer+assertions (active)

$ port installed llvm-3.5
The following ports are currently installed:
  llvm-3.5 @3.5-r210448_0+assertions (active)

Why is the clang-3.4 installation triggered anyway when I try to update the installed clang-3.5 port?

[jeremyhu (Jeremy Huddleston Sequoia)]

Well what variants are being used by the clang-3.4 install that is trying to take place?

As for why clang-3.4 is being used, it's probably because your system compiler is too old:

# llvm-3.5 and later requires a C++11 runtime
# XCode 4.3's clang (318.x) fails per https://trac.macports.org/ticket/44161
# XCode 4.5's clang (421.11.66) fails due to http://llvm.org/bugs/show_bug.cgi?id=20184
# Xcode 4.6.x's clang (425.0.28) works, assuming 425.0.24 from 4.6.0 works too
compiler.blacklist *gcc* macports-clang-2.9 macports-clang-3.0 macports-clang-3.1 {clang < 425.0.24}

[oliver.bock@…]

Well what variants are being used by the clang-3.4 install that is trying to take place?

Well, I suppose the default variants since clang-3.4 is installed as a dependency of the clang-3.5 upgrade (see above). That would mean "+analyzer". Looking at the distfile fetch, however, it seems that following variants (matching the clang-3.5 variants, see above) are used:

Attempting to fetch clang-3.4-3.4.2_6+analyzer+assertions.darwin_10.x86_64.tbz2

Does that help?

[oliver.bock@…]

As for why clang-3.4 is being used, it's probably because your system compiler is too old:

Hm, but clang-3.5 is already installed on that system (see above) and I'm just trying to update it as usual. If 3.5 would be fundamentally unsupported by that particular system (OS X 10.6.8, i686-apple-darwin10-gcc-4.2.1, i686-apple-darwin10-llvm-gcc-4.2 (GCC) 4.2.1), I shouldn't have been able to install it in the first place.

[punch@…]

So I completely uninstalled clang-3.4 and its dependencies. Then I tried a reinstall (without cleaning). I got the following:

sudo port install clang-3.4

Error: Requested variants "+analyzer+arm_runtime" do not match original selection "+analyzer+arm_runtime+assertions". Please use the same variants again, perform 'port clean clang-3.4' or specify the force >option (-f). To report a bug, follow the instructions in the guide:

​​http://guide.macports.org/#project.tickets

Error: Processing of port clang-3.4 failed

I did a clean then tried the reinstall and it worked without a problem. I'm not clear why I'm getting the arm-runtime variant, but at least it installed without an error this time.

[jeremyhu (Jeremy Huddleston Sequoia)]

So it looks like you're trying to install a +asserions clang-3.4 with a -assertions llvm-3.4. That is not supported. We should use the active_variants port group to enforce that.

[oliver.bock@…]

So it looks like you're trying to install a +asserions clang-3.4 with a -assertions llvm-3.4. That is not supported

That's right. As soon as I installed llwm-3.4 +assertions the upgrade went fine, including clang-3.4 and clang-3.5. I still don't see how that inconsistency could manifest itself in the first place though... Oh well...

Thanks!
