Trouble building on OS X 10.11.6 (El Capitan)

[andyby...@gmail.com]

Hello!

I'm having trouble getting libmv to build on OS X 10.11.6.  

I'm using the latest revision from:

    git://git.blender.org/libmv.git 

And the readme instructions from the deprecated github repo.

When I run the vanilla make command it has build errors that seem to be related to the out of date third party libraries and C++11 updates to the OS X SDK.

I used cmake to configure the build:

---------------------------------------------------------------

cd ~/gitrepo/libmv

mkdir build

cd build

cmake ../src -DCMAKE_OSX_DEPLOYMENT_TARGET=10.6 -DCMAKE_CXX_FLAGS_DEBUG="-g3 -O0 -fno-inline -std=c++11" -DCMAKE_C_FLAGS_DEBUG="-g3 -O0 -fno-inline" -DCMAKE_OSX_ARCHITECTURES=x86_64 -DCMAKE_BUILD_TYPE="Debug" -DWITH_SYSTEM_CERES=YES

CMake Warning (dev) at CMakeLists.txt:21 (CMAKE_MINIMUM_REQUIRED):

  Compatibility with CMake < 2.4 is not supported by CMake >= 3.0.

This warning is for project developers.  Use -Wno-dev to suppress it.

The make command fails when building numeric.o

(output before the error excluded for brevity)

---------------------------------------------------------------

I'm not sure which part I've got wrong here.  Should I not be using the OS X 10.6 SDK, or should I try to update the third party Eigen source?

Alternatively, should I instead use the libmv source included in the blender?

  https://git.blender.org/blender.git

The libmv change log in the blender repo shows more recent updates than the standalone libmv repo.

I'm just wondering which is correct repo to be using if I want to build libmv and the included tools.

Thanks for creating and open sourcing such an amazing library, really looking forward to trying it out!
