Hi I trying to run FANN in ubuntu.

I installed the package

*
http://space.dl.sourceforge.net/project/fann/fann/2.0.0/libfann2_2.0.0-1_i386.deb
*

However whenever I am trying to run it as a c program given in
http://leenissen.dk/fann/html/files2/gettingstarted-txt.html#Training

It gives me following error

***@neil-laptop:~/ann$ cc fann.c
fann.c:1:18: error: fann.h: No such file or directory

Please help how to include the library in c program.

Thanks and Regards

Hi Neil,
You can list the files in a deb package with "dpkg -c". In this
case, we find that there is no fann.h included.

This is apparently the package for docs and shared libraries only.
You want the dev library

I installed the dev package. The header file error went away but getting the
following error now

***@neil-laptop:~/PR/ann$ gcc fann.c
