I am trying to compile something that uses Google's sparsehash include files.
libs/include/google/dense_hash_map:93:60: error: ext/hash_fun.h: No such file or directory
^Cmake: *** [all] Interrupt
When you compiled sparsehash, did you build it with the same compiler that you are using now? When I build it, it finds hash_fun in
tr1/functional, not in
m4/stl_hash_fun.m4, you can see the list of places that it searches.
