llvm-4.0 build fails due to libtool error on SnowLeopard when built with clang-3.9, but succeeds when built with clang-3.7

[kencu (Ken)]

Here's what I saw on Snow Leopard when building llvm-4.0.

building with clang-3.9:

On this particular machine, /Developer refers to Xcode 4.2.

I have another version of libtool in /opt/local/bin/libtool, but this is not called by the llvm-4.0 cmake script.

I'm not sure if the object files built with clang-3.9 are different than object files built with clang-3.7.

[kencu (Ken)]

$ /Developer/usr/bin/libtool -V
Apple Computer, Inc. version cctools-809

[jeremyhu (Jeremy Huddleston Sequoia)]

You should install the cctools port.

[kencu (Ken)]

Yeah, that's been there for quite a while. The cmake build script must be specifically targeting the libtool at /Developer/usr/bin/libtool. I'll see if I can figure out where & why that happens.

$ port -v installed cctools
The following ports are currently installed:
  cctools @895_3+llvm39+universal-llvm34 (active) platform='darwin 10' archs='i386 x86_64' date='2016-12-24T17:48:26-0800'

$ which libtool
/opt/local/bin/libtool

$ libtool -V
Apple Inc. version cctools-895

[kencu (Ken)]

right here in CMakeList.txt

 execute_process(COMMAND ${CMAKE_XCRUN} -find libtool
 OUTPUT_VARIABLE CMAKE_LIBTOOL

$ xcrun -find libtool
 /Developer/usr/bin/libtool

I suppose CMAKE_LIBTOOL could be pushed in by the Portfile on systems that need it, if the llvm group doesn't want to monkey with the CMakeLists.txt logic.

[kencu (Ken)]

Oh, I see. You already have that.

Maybe this xcodeversion test will need to be bumped up past 4.2 then. Not sure where it needs to be set.

# I'm not sure the exact version of Xcode that has a good enough libtool, but 3.2.6 seems to get past this when 3.1.4 doesn't:

    depends_build-append port:cctools
    depends_skip_archcheck-append cctools

}

[kencu (Ken)]

I changed the xcode test to 4.3 (which is beyond the xcode I have installed), and now clang-4.0 builds through with clang-3.9 on SnowLeopard, using macport's cctools-895 libtool.

main.log with failure due to Xcode version number comparison with 4.3

[kencu (Ken)]

Your build attempt is somehow still calling /Developer/usr/bin/libtool as you can see, which does not work to link object files built with clang-3.9 on 10.6 as it's too old.

The fix I suggested above changes that to /opt/local/bin/libtool from cctools, which does work. Please check that bit carefully in the llvm-4.0 build file you edited and see if you altered it correctly. Or as I said in your other ticket, just check out my SnowLeopardPorts repo where it is all done for you.

I would submit a PR for this for the main MacPorts repo, but Jeremy understands bootstrapping dependencies much better than I do. Obviously he is very busy these days.

Indeed:

Or did I miss the proper build file?

There are two places where the xcodeversion is checked. You need to change the second one from 3.2.6 to 4.3.

I think you've changed the first one from 6.0.0 to 4.3.

Or, if you get super stuck, and don't want to use my repo, just build llvm-4.0 with clang-3.7, which 10.6 can link with its stock tool chain.

Replying to kencu:

I must have made an error when I searched in vi for vercmp. Doing it again and more controlled I found the second occurrence and now

  clang-4.0 @4.0.0_0+analyzer+libstdcxx (active)
  llvm-4.0 @4.0.0_0 (active)

are built. Building llvm-4.0 with polly is certainly not recommended because the ppl port is installed and also used by other ports.

Thank you, Ken!

[kencu (Ken)]

great! Progress! but but please don't forget that clang-4.0 is still broken on snow leopard unless you did that patch I mentioned in here 54135.

Over the cooler night the patched Clang 4.0 built. I wonder whether Poppler 0.55 and TeX Live 2017 will build…

[jeremyhu (Jeremy Huddleston Sequoia)]

I'm thinking that base should add port:cctools to depends_build when using a macports compiler

[kencu (Ken)]

even if we did that (which is a fine idea) I think we'd still need this bit because if it is not specified, cmake will try to find one and it finds the /Developer one.

-DCMAKE_LIBTOOL=${prefix}/bin/libtool

[jeremyhu (Jeremy Huddleston Sequoia)]

Please give this a try for the change in base:

​https://github.com/jeremyhu/macports-base/commit/90eb1ae7903e9b24fa47c8e2a2adef3e50e69fb3

As for -DCMAKE_LIBTOOL=${prefix}/bin/libtool, IMO, that should be default. We should fix how CMAKE_LIBTOOL gets discovered.

llvm-{3.8,3.9,4.0,devel}: Depend on the cctools port whenever we use macports-clang-*

Closes: #54129

Signed-off-by: Jeremy Huddleston Sequoia <jeremyhu@…>

[jeremyhu (Jeremy Huddleston Sequoia)]

Reopening to continue the discussion for base. That change just addresses the immediate need for the llvm ports.

[Ionic (Mihai Moldovan)]

This doesn't seem to work as intended.

For some reason, the code that adds the cctools dependency and checks whether cctools have been added as a dependency to add the cmake/configure option is executed before compiler blacklisting takes place - which means that gcc-4.2 is still selected as the compiler and everything fails badly.

If I wrap both checks into a pre-configure block, delaying execution, it starts working as intended.

[kencu (Ken)]

Yes. I have default_compiler set which would override that for me, so I wouldn't see that.

[jeremyhu (Jeremy Huddleston Sequoia)]

Does it work just adding the CMAKE_LIBTOOL block behind pre_configure? configure.compiler should always evaluate after the blacklisting, so I doubt that is problematic.

[Ionic (Mihai Moldovan)]

No, it doesn't. ${configure.compiler} is being used before blacklisting, which keeps it at gcc-4.2 and hence any dependencies upon cctools are not added to depends_build. This holds for unpatched base.

The situation is different if I backport your base patch (though we cannot rely on that for the moment): since the cctools dependency is added by base early enough, the cmake option is also added in the pre-configure block.

Take a look at these two log files - one made with vanilla base, the other one with the backported patch. I've added ui_debug statements to the Portfile for printing out ${configure.compiler} and $PortInfo(depends_build). Two of them in global scope (before and after the block that should add the cctools dewpendency) and one of them in pre-configure scope.

For now, we should delay both blocks by putting them into the pre-configure phase.

[Ionic (Mihai Moldovan)]

vanilla base attempt

[Ionic (Mihai Moldovan)]

patched base attempt

[jeremyhu (Jeremy Huddleston Sequoia)]

${configure.compiler} is being used before blacklisting

Well then that is the issue that needs to be addressed. Wrapping it all in a pre-configure script isn't the solution there.

[jeremyhu (Jeremy Huddleston Sequoia)]

In b6107767144ad4774c2d9bd13c6c77890b3d8ba6/macports-ports, that block has been moved after the blacklisting.

[Ionic (Mihai Moldovan)]

That works great. Thanks!
