problem with compiling files

[perfectblue]

Hello,

I'm a graduate student and now working on my master thesis in a company. I'm planning to build a neural network with FANN on Linux. Since I cannot install anything on the company computer myself, I asked the IT people in the company to intall the library for me.

When I tried to compile the file I got this kind of error:
/tmp/ccQT1448.o(.text+0x19): In function `main':
: undefined reference to `fann_create_from_file'
/tmp/ccQT1448.o(.text+0x3c): In function `main':
: undefined reference to `fann_run'
/tmp/ccQT1448.o(.text+0x7d): In function `main':
: undefined reference to `fann_destroy'
collect2: ld returned 1 exit status

I took the second example from the tutorial (the Simple Execution Example) so I think there should be no mistake in the code. And it's the same with all other examples when I tried to compile them.

I guess there might be something wrong when installing the FANN library, but the IT peoplehaven't figure it out (not yet).

Do anyone has any idea what could be wrong?

Thank you,

Jene

Are you #including "fann.h" ?

Seems like you are not linking correctly with the library, how does your
compile command line look like?

does it include -l fann?

What are the exact commands are you using to compile the file? You
should be linking to libfann. For example, if you are using GCC, you
would make sure you pass the flag "-lfann".
