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

It was created by dx configure 4.4.4, which was
generated by GNU Autoconf 2.71.  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 --disable-dependency-tracking --disable-silent-rules --docdir=/usr/share/doc/opendx-4.4.4-r8 --htmldir=/usr/share/doc/opendx-4.4.4-r8/html --libdir=/usr/lib64 --with-x --without-javadx --without-szlib --without-cdf --without-netcdf --without-hdf --without-tiff --without-magick --disable-smp-linux
