How to use Google's Sparse Hash

In my project, I am asked to use Google's Sparse Hash. But I don't even know where to start. These are steps that I take and do not get my code even compiled:

The error is

Multiple markers at this line
- fatal error: google/sparse_hash_map: No such file or directory
- Unresolved inclusion: <google/sparse_hash_map>

I really don't know what to do. Waiting for your helps.

You could locate sparse_hash_set in your computer ( locate sparse_hash_set ) and create a symbolic link from the directory where sparse_hash_set is installed to google/sparse_hash_map.

test@ubuntu:~# updatedb                   # To update the locate database
test@ubuntu:~# locate sparse_hash_map
/usr/include/google/sparsehash/sparse_hash_map
test@ubuntu:~# ln -s /usr/include/google/sparsehash/sparse_hash_map /usr/include/google/sparse_hash_map

Sorry if this is obvious, but if your google hashmap source is already in the same directory as your code is, you should probably try:

#include "sparse_hash_map"

instead of

#include <google/sparse_hash_map>

Worse case, include -I</directory/to/google/sparse_hash_map> in your compile command line. Good luck!
