Hi Daniel,
I don't have an OSX system to test against so have to defer to OSX users
for maintaining the build, I can only provide general guidance.
>From the look of the error line:
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/sys/cdefs.h:707:2:
error: Unsupported architecture
#error Unsupported architecture
It looks to me like part of the 10.11 SDK doesn't support build under all
architectures. You'll need to go into Cmake and select change the
architecture this is built against. Have a look at the
CMAKE_OSX_ARCHITECTURES value.
Just look at the OpenSceneGraph/CMakeLists.txt lines where it sets
CMAKE_OSX_ARCHITECTURES It has the following:
# Set defaults for Universal Binaries. We want 32-bit Intel/PPC on
10.4
# and 32/64-bit Intel/PPC on >= 10.5. Anything <= 10.3 doesn't
support.
# These are just defaults/recommendations, but how we want to build
# out of the box. But the user needs to be able to change these
options.
# So we must only set the values the first time CMake is run, or we
# will overwrite any changes the user sets.
# FORCE is used because the options are not reflected in the UI
otherwise.
# Seems like a good place to add version specific compiler flags
too.

# No Universal Binary support

# but the SDK detection is too unreliable here.
ENDIF()
ENDIF()
Note, the line :
IF(${OSG_OSX_SDK_NAME} STREQUAL "macosx10.8" OR ${OSG_OSX_SDK_NAME}
STREQUAL "macosx10.9" OR ${OSG_OSX_SDK_NAME} STREQUAL "macosx10.10")
Doesn't include the 10.11, so try adding this into the list.
Robert.
