Bam, your patch worked great. It does print this at some point but still links
fine & works OK with my board.
*** Warning: linker path does not have real file for library -lftd2xx.
*** I have the capability to make that library automatically link in when
*** you link to this library. But I can only do this if you have a
*** shared version of the library, which you do not appear to have
*** because I did check the linker path looking for a file starting
*** with libftd2xx but no candidates were found. (...for file magic test)
*** The inter-library dependencies that have been dropped here will be
*** automatically added whenever a program is linked with this library
*** or is declared to -dlopen it.
*** Since this library must not contain undefined symbols,
*** because either the platform does not support them or
*** it was explicitly requested with -no-undefined,
*** libtool will only create a static version of it.
I made sure to check I didn’t have any of my old renamed libs hanging around.
BTW – does anyone think it might be useful to print a message if Cygwin/mingw
is detected & ftd2xx is not, that people should see documentation about
enabling that? I admitably was first a little confused about getting ftd2xx
working, as had followed the instructions for Linux like an idiot.

I don’t know how I was able to make it so complicated. As it turns out libtool
is perfectly able to handle windows libraries exactly the same way it does with
regular libraries. Just link with –lftd2xx… no renaming of libraries are
required.
Here is a patch for you. Please try it and report back to the list.

A very interesting thread about windows import libraries, a bit old but
addresses the problem. Unfortunately there’s no solution….

I recently went to build with f2xx, and came across this problem again.
Your “fixes” to the .ac file worked for me as well. I’d like to see this pushed
into a real solution somehow though, as I’m sure it will frustrate many more
people in the future, any ideas?

Åke,
It’s not just you; I encountered this problem over a year ago. It seems that
libtool is supposed to automatically determine the dependency on ftd2xx.lib,
but doesn’t do so. It generated a dependency file that was basically empty.
Unfortunately I don’t know libtool well enough to know how to fix it
“correctly”.
I believe if you look in src/.libs/liburjtag.lai (or maybe it was just
src/liburjtag.la?), you can see the dependencies that libtool generated. Mine
looks like this:
# liburjtag.la - a libtool library file
# Generated by ltmain.sh (GNU libtool) 2.2.6b Debian-2.2.6b-2ubuntu1
#
# Please DO NOT delete this file!
# It is necessary for linking the library.
# The name that we can dlopen(3).
dlname=''
# Names of this library.
library_names=''
# The name of the static archive.
old_library='liburjtag.a'

Notice the complete lack of any mention of ftd2xx. (The file src/liburjtag.la
only differs in “installed=no”.)

Subject: [UrJTAG-dev] Trouble linking with ftd2xx.lib
I had trouble linking with FTDI windows library. I finally had to resort to
change the configure script, then rename the library to libftd2xx.a to get the
linking to complete. It seems like the ftd2xx.lib is completely missing from
the link command line.
Any Idea what the problem is?
