falconn/src/examples/glove/makefile seems wrong

[jinxw]

when I run

./make

it will say
../../include/falconn/wrapper/../core/flat_hash_table.h:13:23: fatal error: serialize.h: No such file or directory
so I need to run
g++ -std=c++11 -Wall -O3 -march=native glove.cc -o glove -I ../../include -I ../../../external/eigen -I ../../../external/simple-serializer -pthread
and it goes will

[ilyaraz]

Thanks for catching this!

on current master even when adding simple-serializer to the includes path compilation fails with errors:

[Jeffery-Meng]

It seems that "unsigned long" is not recognized by "IsElementary". I can compile after adding the following lines.

template <>
struct IsElementary : std::true_type {};

[dspcad]

Copy and paste the code below to external/simple-serializer/serialize.h
template <>
struct IsElementary<. long unsigned int. > : std::true_type {};

I can compile the code.
