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

It was created by Protocol Buffers configure 3.20.1, which was
generated by GNU Autoconf 2.71.  Invocation command line was

  $ ./configure --target=nios2-buildroot-linux-gnu --host=nios2-buildroot-linux-gnu --build=x86_64-pc-linux-gnu --prefix=/usr --exec-prefix=/usr --sysconfdir=/etc --localstatedir=/var --program-prefix= --disable-gtk-doc --disable-gtk-doc-html --disable-doc --disable-docs --disable-documentation --with-xmlto=no --with-fop=no --disable-dependency-tracking --enable-ipv6 --disable-nls --disable-static --enable-shared --with-protoc=/home/buildroot/autobuild/run/instance-2/output-1/host/bin/protoc
