I just downloaded the tar.bz2, unpacked it, configure'd it and called make. Best regards, Erik

I think your patch wouldn't be enough to actually run QEMU, because the path to libusbx.so is not in LD_LIBRARY_PATH (and if you can change LD_LIBRARY_PATH, you can also change PKG_CONFIG_PATH). The right way to do it is: * add --prefix=$HOME to your configure command line. * call "make install" after "make" * add $HOME/lib to your LD_LIBRARY_PATH * add the right subdirectory of $HOME/lib to your PKG_CONFIG_PATH * test that it works with "pkg-config --cflags libusb-1.0" * configure QEMU with no extra options Paolo

I will try that and let you know if it worked. Best regards, Erik

Works fine for me. Best regards, Erik
