I don't know if the stuff below will help you, I did not experience any direct hassel during cygwin installation. Can you be more specific to where your build failed? In my config.log I can see that libusb is not found, but -lusb works. So ./configure do not stop for me I have libusb in /lib and /usr/lib and headers in /usr/include Stuff: less /usr/share/doc/Cygwin/libusb-win32-0.1.12.1.README: The driver is _not_ installed by default since it is a potential security hole. For actually installing the driver, run /usr/sbin/libusb-install And run testlibusb-win for checking that it succeded: it should print DLL version: 0.1.12.1 Driver version: 0.1.12.1 and a list of your USB devices. Use /usr/sbin/libusb-uninstall for uninstalling them (it is performed at package removal). /Ulf

However, I am tearing my hair out over this: Gnuradio build process gives message 'libusb not found' and builds with certain key services missing. Libusb-win32 is definitely installed, as part of the regular Cygwin setup, but this did not result in any libusb.pc file in any of my PkgConfig folders. These are the packages with .pc files $ ls -l /usr/local/lib/pkgconfig/ total 5 -rwxr-xr-x 1 Paul None 221 Sep 8 13:46 fftw.pc -rw-r--r-- 1 Paul None 221 Sep 3 13:54 fftw3f.pc -rw-r--r-- 1 Paul None 297 Sep 8 14:09 gnuradio-core.pc -rw-r--r-- 1 Paul None 289 Sep 8 14:05 gnuradio-omnithread.pc -rw-r--r-- 1 Paul None 243 Sep 3 10:57 portaudio-2.0.pc The same files are also found in /usr/local/bin/pkgconfig. Eric blossom posted these as part of a response to a similar query: [EMAIL PROTECTED] ~]$ ls -l /usr/local/lib/pkgconfig/ total 24 -rw-r--r-- 1 eb wheel 218 2006-03-06 19:17 fftw3.pc -rw-r--r-- 1 eb wheel 219 2006-03-06 19:10 fftw3f.pc -rw-r--r-- 1 eb eb 291 2006-09-10 11:06 gnuradio-core.pc -rw-r--r-- 1 eb eb 206 2006-08-26 22:15 libusb.pc -rw-r--r-- 1 eb eb 245 2006-08-23 21:01 portaudio-2.0.pc -rw-r--r-- 1 eb eb 238 2006-09-10 11:06 usrp.pc Note that I appear to be missing both libusb.pc and usrp.pc files. Looking around the web, I found that others having the same or similar problems were advised to install 'libusb-devel'. Here's a typical example of such advice: -----If ./configure complains about missing package "libfoo", the first thing to try is to install "libfoo-devel".----- I had trouble finding any libusb-devel in a tarball, but located one here: http://sourceforge.net/project/showfiles.php?group_id=153722&package_id= 174259 <http://sourceforge.net/project/showfiles.php?group_id=153722&package_id =174259> However, the above package has no 'configure' file. (It does have 'configure.in', but is definitely missing 'configure'.) I was expecting to be able to use the following commands to get this installed: ./configure make make check make install Obviously, I can't proceed without 'configure'. Any suggestions for how to proceed will be greatly appreciated. Paul Mathews
