To compile 32-bit version on 64-bit system (Debian Squeeze), I had to change the Makefile according to the following patch:

diff --git a/Makefile b/Makefile

 CFLAGS += -m32
+LIBS=-ldl /lib32/libusb-0.1.so.4 -lpthread
 endif
 
 FTDI := $(shell libftdi-config --libs 2>/dev/null)

Use LD_PRELOAD variable before starting ISE. I use the following script to start ISE:

#!/bin/bash
. /opt/Xilinx/10.1/ISE/settings32.sh
export LD_PRELOAD=/home/xxx/src/xilinx/usb-driver/libusb-driver.so
