Good morning,
I've got the same problem, here are the syntax errors mentionned bye the cygwin64 on windows7 :

Is there someone that can help ?
Thanks

I try to execute the examle.cpp file of Project-OSRM. I did the following steps:
build OSRM from source as described here
in new terminal: cd osrm-backend/example
in the terminal: cmake ..
in the terminal: cmake --build .
in the terminal: sudo cmake --build . --target install
move the maps contractor, engine, extractor, partition, storage, util from /usr/local/include/osrm to /usr/local/include (else error maps are not in /usr/local/include)
in the terminal: g++ -std=c++11 example.cpp -o example
But I get the error
‘underlying_type_t’ in namespace ‘std’ does not name a template type
static_cast<std::underlying_type_t<RouteParameters::AnnotationsType>>
Does anyone have a idea what I'm doing wrong or what is going wrong and how to solve this?

underlying_type_t requires C++14. To be able to use it pass -std=c++14 to your compiler.
Don't forget to
#include <type_traits>
This missing directive also lead to the same (confusing) error message.
I am trying to solve an integer linear program using SCIP. The beta version that I require (for exact solving) is given at:

As linked there, the source code is at:

After some searching, I have noticed that dbl_EGeHeap_t is not defined in the source code, and that seems to be throwing errors.
On searching online, it seems to be the case that it was defined in EGlib 2.6.15 (https://conexo.dii.uchile.cl/SVN/EGlib/EGlib2/tags/EGlib-2.6.15/TEmplate/dbl_eg_eheap.h), but the corresponding file in 2.6.20 does not have the definition.
Has anybody else experienced this? I badly need a solution to this.
I was building Python (3.4 dev version) from source as a framework on OS X 10.8. I'm a relative newbie to Mac OS X internals and couldn't figure out why the OS X framework headers caused these errors. Can someone please give me some pointers?
I use the latest version of GNU gcc on my mac instead of the Apple supplied LLVM compiler. Perhaps, that's causing a compatibility problem.

The errors correspond precisely to the 'block' extension Apple developed for C, C++ and Objective-C languages. GCC (the GNU version) doesn't recognize the block occurences and complains.
I'm having serious problems running some standard commands such as sleep() with g++-mp-4.8 downloaded from macports. I don't have any of these problems compiling with llvm-g++-4.2.
This is quite annoying, because I'm trying to use C++11 features in this program.
Here is the read out from the compiler - I'm really sorry it's so long, I just have no idea what to do with it:

As suggested in the hints, I got rid of all the outdated -I/'s and set up the clang++ compiler as in Eclipse, Macos 10.8 and C++11
There were some clashes with between my code and the stl, but they were easy to hunt down from the console output.
