breaks… at least until the grand rebuild structuring comes along. :slight_smile:

Thanks, guys. I’ve made a note of this to keep in mind while we’re
working on the restructuring.

It looks like it’s part of autoconf’s machinery…
On my system I found it in /usr/share/autoconf/autoconf/general.m4
around line 558.

AC_SUBST(prefix, NONE)dnl

There’s a discussion here that’s relevant:

I think Josh’s suggestion will work. It probably has to occur after
AC_INIT (or maybe AC_PREREQ). Not sure if there’s anything else that
needs to run first.

In other news,
UHD can now compile against pre-built libusb1.0 windows binaries:

Runtime operation has yet to be confirmed.

Thanks!

For those of you following the uhd windows support: usrp1 seems to be
working with libusb-1.0 under windows. See the build notes here:
http://www.ettus.com/uhd_docs/manual/html/build.html#libusb-cmake-notes

Here is a link to the windows drivers on the main wiki page:

And for those Gentoo/Ricer/Overclocker types: bulk transfer send and
recv parameters are now exposed to the user through the device address:

Enjoy!
