This is due to two issues (one offline and one in libskylark) being reported claiming that there was a mistake in Elemental's namespacing. Both issues seem to be caused by argument-dependent lookup not being widely appreciated.

@rhl-
Wow.
Jack Poulson
@poulson
yes, ADL seems to be somewhat of a hack
the story Koenig tells in his blog post on Dr. Dobbs gives that away
but I am surprised no preference is given to the current namespace

Apparently sudo is generally required for the configure, make, and make install stages of CMake now
Recent versions of CMake's ExternalProject_Add create directories in the install folder during the configure stage

@jeffhammond
as if i needed another reason to hate cmake.
so cmake no longer works if you don't have elevated privileges?
and if someone manages to create malware inside of cmake tests, does that make cmake a virus?
Jack Poulson
@poulson
you only need elevated privileges in the configure or make stages if make install would have required the same privileges
so the privilege issue only applies if the user selected an installation location that required said privileges
but I honestly completely agree that rickety code that no one ever reads would be a great place to slip in something devious

@rhl-
Hey jack, how is the progress going on Hessenberg QR ? I'd very much like to cut an Elemental Release :)

the intra-block chase for a multi-bulge algorithm now has a prototype

@poulson link is dead

@poulson
it was moved into the Sweep/ folder

Intel 17.0.1 (20160921) builds Elemental cleanly, at least without QUAD support. I expect it will be released pretty soon, based upon the important bugfixes it contains. The historical trend is that update 1 drops in October or November (https://software.intel.com/en-us/articles/intel-compiler-and-composer-update-version-numbers-to-compiler-version-number-mapping).

Thanks for sharing that! It is definitely good news.
Ryan H. Lewis
@rhl-
@jeffhammond that is awesome. Once it is released we should setup jenkins CI with the intel compiler.

@poulson i'm trying to use CLion with Elemental. I'm having a lot of trouble with it. Have you ever tried to use CLion?
Ryan H. Lewis
@rhl-
Error:CMAKE_OSX_DEPLOYMENT_TARGET is '10.11' but CMAKE_OSX_SYSROOT:
""
is not set to a MacOSX SDK with a recognized version. Either set CMAKE_OSX_SYSROOT to a valid SDK or set CMAKE_OSX_DEPLOYMENT_TARGET to empty.
I tried setting the appropriate value to empty but it does nothing.

I also see:

Warning:Ignoring CMAKE_OSX_SYSROOT value:
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk
because the directory does not exist.

And indeed it does not.

Ryan H. Lewis
@rhl-
Ah I see, Clion bundles cmake, asking it to use the one I use on the command line fixes everything.
Jack Poulson
@poulson
I've never seen that error
I briefly tried CLion once
do you think it's a CMake, CLion, or Elemental issue?
Ryan H. Lewis
@rhl-
Well, I got past that one by asking CLion to use my system cmake instead of the pre-baked on
now I have a problem that the debugger isn't working properly
i think thats because Elemental is overriding the build type
and CLion doesn't set the build type the same way
Jack Poulson
@poulson
you can specify the build type
if it is Debug or Release, nothing should be overwritten
Ryan H. Lewis
@rhl-
right, i think CLion doesn't set the type using the standard way
so what is happening is Elemental somehow overrides the decision CLion makes
im trying to figure it out
.. working on BFGS. I have an initial implementation, trying to get the line searchs
i'm going to start with wolf and strong wolf
and use tag dispatching to provide options.
Ryan H. Lewis
@rhl-
Hm. Nope. just confirmed CLion is doing the right thing there. must be a bug in Clion or something
Ryan H. Lewis
@rhl-
@poulson just pushed a branch with my initial BFGS impl. any thoughts on test cases appreciated
Jack Poulson
@poulson
a long time ago I was working on BFGS for logistic regression
but I never finished it
you might want to look into Fisher's scoring method
Ryan H. Lewis
@rhl-
do you have the branch? My line search doesn't work for a simple 1x1 example :(
Jack Poulson
@poulson
what do you mean?
