Hi Silvio. You're installing an ~x86 package on an x86 machine, I think.
Are you doing that on purpose?

I don't know if that is causing the error, but it sometimes causes problems.

Have i something not understand, i make emerge -av clang and become

gentoomobile siefke # emerge -av clang

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild N ~] sys-devel/llvm-3.4:0/3.4 USE="clang libffi ncurses python static-analyzer xml -debug -doc -gold -multitarget -ocaml {-test} -udis86" PYTHON_TARGETS="python2_7 -pypy2_0 -python2_6" VIDEO_CARDS="-radeon" 0 kB
[ebuild N ~] sys-devel/clang-3.4-r100:0/3.4 USE="python static-analyzer -debug -multitarget" 0 kB

Total: 2 packages (2 new), Size of downloads: 0 kB

The following keyword changes are necessary to proceed:
(see "package.accept_keywords" in the portage(5) man page for more details)
# required by sys-devel/clang-3.4-r100
# required by clang (argument)
=sys-devel/llvm-3.4 ~x86
# required by sys-devel/llvm-3.4[clang]
=sys-devel/clang-3.4-r100 ~x86

Use --autounmask-write to write changes to config files (honoring
CONFIG_PROTECT). Carefully examine the list of proposed changes,
paying special attention to mask or keyword changes that may expose
experimental or unstable packages.

Then emerge --autounmask-write -av clang and after dispatch-conf i run
emerge -av clang and become the error. I not understand what you mean?

Hello,

ok the version 3.3 run without problems, i think the 3.4. make troubles
and the package Maintainer from Gentoo has hardmasked.

llvm-3.4 is not hardmasked. It is marked ~x86 which is something very
different.

The mistake you made is using --autounmask-write
That feature writes local package.unmask entries to satisfy dependencies.
It's a very blunt tool, it blindly keywords whatever it thinks it needs
to and when it goes wrong, it goes very wrong quickly.

You are running x86. If you want a package that is marked ~x86 then you
need to take very careful note of everything that must be keyworded to
build that package. If you want something basic like llvm that will
cause many other packages to be upgrade with it, then you need to be
especially careful.

--autounmask-write is not an intelligent tool. It's not like the stable
tree which receives testing and you can mostly trust portage because the
combination has been tested. What it does is throw a bunch of untested
combinations into the mix and leave you hoping that it might work out.

Correct, i mean Clang in version 3.4 is hardmasked. I want install clang
alone llvm i not need. I think mesa use llvm too but i has not set the
use flag.

The tool write package.accept_keywords, a package.unmask i have not on
system. Yes its a shit tool, normal i make echo "package ~x86" >> package.a..
What should do? Should i compile without portage? Should i not use? When i
want emerge clang is masked, ok why? FreeBSD use it and say is stable.
FreeBSD maybe not the reference on earth but the BSD's make a good job.
When i saw all versions of Clang is masked.

I use much x86 packages and has never problem. For example i use calibre
without x86 flag i must use calibre in version 1.2. but the version 1.20
works stable and fine and i can use with my tablet, because i read much
when im on the road.

https://packages.gentoo.org/package/app-text/calibre

So i think for some packages is accept between risk and compromiss. I find
better x86 flag better as install software in /usr without portage.

I don't know why I'm replying, as I'm no expert. So, I could be way off,
but:

From a google search:

Clang /ˈklæŋ/ is a compiler front end for the C, C++, Objective-C and
Objective-C++ programming languages. It uses LLVM as its back end ...

That's what you should do. The output will tell you what files need
updating. In some cases, I just let it write, like for a big perl
package with lots of modules from the overlay. Otherwise it's faster to
just copy and paste the output.

No.

https://bugs.gentoo.org/show_bug.cgi?id=408963 maybe?

Isn't FBSD more similar than, say, Linux, to what OSX is, sort of?

Yep. Sometimes you have to unmask stuff, but portage can handle it then.

Anyway, I hope any of this helps. Good luck!

I could be way off. But I think of OSX as being FBSD built for people that don't know how to use a computer.

No, just stop using automated tools to unmask/keyword everything based
just on depends. Do it yourself, then you know what you unamsked/keyworded.

Nobody suggested you stop using portage, I only said to stop hitting the
system with a big hammer to get things to build.

Before this gets out of hand..

1) clang-3.4 is not hardmasked either, so you need to set ~x86 keyword
for that package as well as for llvm - because:

2) clang is only a metapackage, without any contents on its own.
The compiler binaries are part of the llvm package. You simply cannot
have "clang without llvm".

3) FreeBSD indeed uses clang as default compiler, but uses 3.3 since
3.4 still has quite a few new and exciting bugs.

Hope that clears things up.
