Re: problem including and compiling with ftdi library

[Sab V <madmanzigbee@xxxxxxxxx>]

Check your linker flags once again . Try looking at some of these Makefiles to understand what libftdi needs to compile - http://developer.intra2net.com/git/?p=libftdi;a=tree;f=examples;h=d9e2ba38d9b2017d7b326b08b27b9a74e1133888;hb=HEAD.

You can add the -I flag to include directories to the path

Hello, I just installed the libraries following the provided instructions. I’m on Ubuntu operative system.

If I try to compile the example simple.c, inclunding <ftdi.h> I found this error.

gcc simple_ftdi.c -o myprogram

compilation terminated.

 

If I include <libftdi1/ftdi.h> instead of <ftdi.h> I obtain these errors.

gcc simple_ftdi.c -o my_program

I tried to solve including manually the file ftdi.c but it doesn’t work. What I can to compile a program? 

I appreciate all of your help
