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

It was created by the fast lexical analyser generator configure 2.6.4, which was
generated by GNU Autoconf 2.71.  Invocation command line was

  $ ./configure --prefix=/home/buildroot/autobuild/instance-0/output-1/host --sysconfdir=/home/buildroot/autobuild/instance-0/output-1/host/etc --localstatedir=/home/buildroot/autobuild/instance-0/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-doc
