flann make failed

[witnessai]

Hi, all I tried to install flann on Ubuntu using these following steps

$ cd flann-x.y.z-sr
$ mkdir build
$ cd build  
$ cmake ..   
$ make

when I run make, I got following:

In file included from /mnt/hgfs/Linux Share files/flann-1.8.4-src/src/cpp/flann/algorithms/autotuned_index.h:35:0,
                 from /mnt/hgfs/Linux Share files/flann-1.8.4-src/src/cpp/flann/algorithms/all_indices.h:43,

     typedef typename Distance::ElementType ElementType;

the program can not continue， so I terminated the process , I got following：

Try using latest version 1.9.1, you can find it here https://github.com/mariusmuja/flann/releases

The warning should not be a problem, try opening a new window, run top and see if it isn't working hard at compiling it after you run make. It does take a bit of time to compile as far as I remember.

I didn't see the make in a new window after I run top
