This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by libusb-1.0 configure 1.0.24, which was
generated by GNU Autoconf 2.69.  Invocation command line was

  $ ./configure --prefix=/home/buildroot/autobuild/run/instance-2/output-1/host --sysconfdir=/home/buildroot/autobuild/run/instance-2/output-1/host/etc --localstatedir=/home/buildroot/autobuild/run/instance-2/output-1/host/var --enable-shared --disable-static --disable-gtk-doc --disable-gtk-doc-html --disable-doc --disable-docs --disable-documentation --disable-debug --with-xmlto=no --with-fop=no --disable-nls --disable-dependency-tracking --disable-udev
