After fiddling around a bit with makefile, I got it right, = linking the library was missing.

Hi,

I = am a newbie to Arrow. I am trying to create a default memory pool and = use it to allocate, store and read some stuff using C++ = libraries. 

My code looks like below
int =
initializeArrow(int64_t memSize, uint8_t **memStart) {
    arrow::MemoryPool* pool =3D arrow::default_memory_pool();

    arrow::Status status =3D =
pool->Allocate(memSize, memStart);
=
    if (status.ok()) {
        return 0;
    }

    return 1;
}
I am getting an error like below,

Undefined symbols = for architecture x86_64:
  = "arrow::default_memory_pool()", referenced from:
      = initializeArrow(long long, unsigned char**) in main.cpp.o
ld: symbol(s) not found for = architecture x86_64
clang: error: = linker command failed with exit code 1 (use -v to see = invocation)

I looked into https://arrow.apache.org/docs/cpp/examples.html#row-to-columnar= -conversion as = well older stuff on the user mailing list without avail. Can = someone help ?

Thanks in advance
Nirmala
