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

It was created by configure, 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/sooperlooper-1.7.4 --htmldir=/usr/share/doc/sooperlooper-1.7.4/html --libdir=/usr/lib64 --without-gui --disable-optimize --with-wxconfig-path=
