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

It was created by RtAudio configure 6.0.1, which was
generated by GNU Autoconf 2.72.  Invocation command line was

  $ ./configure --prefix=/usr --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --datarootdir=/usr/share --disable-dependency-tracking --disable-silent-rules --disable-static --docdir=/usr/share/doc/rtaudio-6.0.1 --htmldir=/usr/share/doc/rtaudio-6.0.1/html --with-sysroot=/ --libdir=/usr/lib64 --disable-static --without-jack --with-alsa --with-pulse --without-oss
