Hi,

my project code has been tested with dynamic libraries built with the

line below and they work as expected.
gcc -o traffic -L. -Wl,-rpath=/mnt/nas3/proj/usbbb/code/test20
traffic.c -lftdi
the next step was to build using a static libftdi. the archive file
was moved
from src/.libs to my code directory. compile command:
gcc -static -o traffic traffic.c -L. -lftdi
with this command i get undefined references to all of the libftdi
functions.
./libftdi.a(ftdi.o): In function `ftdi_usb_close_internal':
/proj/usbbb/code/test20/libftdi-0.20/src/ftdi.c:68: undefined
reference to `usb_close'
./libftdi.a(ftdi.o): In function `ftdi_usb_find_all':
/proj/usbbb/code/test20/libftdi-0.20/src/ftdi.c:272: undefined
reference to `usb_init'
you need to link against libusb to get 'usb_init' and 'usb_close';
gcc -static -o traffic traffic.c -L. -lftdi -lusb
should do the trick (the dynamic libftdi is already linked against
libusb).
HTH,
cheers
