Dear Uwe Bonnes

I have been trying to build libftdi-1.0 all day without success so I can't see the example you suggested.  I am very interested in this.

I used the instructions in the attached file and I got thru autoscan, but when I try to do any of the other commands (aclocal, autoheader, autoconfig or automake) I get the error message:

"aclocal: `configure.ac' or `configure.in' is required"

I don't know what to do about this.

So, I tried installing libftdi from my repository (Ubuntu 11.10 64Bit) and then tried to compile the program "simple.c" using the command: cc simple.c and it sends me the following error messages:

simple.c:(.text+0x17): undefined reference to `ftdi_init'
simple.c:(.text+0x62): undefined reference to `ftdi_usb_open'
simple.c:(.text+0x7a): undefined reference to `ftdi_get_error_string'
simple.c:(.text+0xc4): undefined reference to `ftdi_read_chipid'
simple.c:(.text+0x100): undefined reference to `ftdi_usb_close'
simple.c:(.text+0x118): undefined reference to `ftdi_get_error_string'
simple.c:(.text+0x150): undefined reference to `ftdi_deinit'

I even tried pointing the include file directily bu chinging the include like to:

#include "/usr/include/ftdi.h"

but the results were the same.

Help!!!

Did you have a look at the stream_test application in the libftdi-1.0
example directory? We use this here to transfer about 15 MByte/s. If you are
interested, I can send you the Verilog code for the other side for an Xilinx
XC6S45LX.

Bye
