I am having the same problem as Peter (compiling source from svn, using ftd2xx, under cygwin). As far as I can tell the problem is with libtool 'harvesting' the symbols when building liburjtag.la. during that step libtool prints a message (output copied manually as I don't have the source/build env. on this machine) make[3]: Entering directory `/home/adyer/urjtag/urjtag/src' /bin/sh ../libtool --tag=CC --mode=link gcc -std=gnu99 -Wall -Wmissing- prototypes -Wstrict-prototypes -Wpointer-arith -g -O2 -I/home/adyer/ftdi-cdm- driver -version-info 0:0:0 -o liburjtag.la -rpath /usr/local/lib tap/libtap.la part/libpart.la lib/libjtaglib.la flash/libflash.la bfin/libbfin.la bus/libbus.la cmd/libcmd.la pld/libpld.la global/libglobal.la -lm /home/adyer/ftdi-cdm-driver/i386/ftd2xx.lib -lintl svf/libsvf.la svf/libsvf_flex.la bsdl/libbsdl.la bsdl/libbsdl_flex.la -lioperm -lreadline libtool: link: warning: undefined symbols not allowed in i686-pc-cygwin shared libraries I am not that familiar with the ins and outs of libraries, dlls & windows, but I wonder if the problem is some update in the FTDI D2XX driver library breaking things. I pulled the library from their site yesterday, version is 2.08.24 ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
