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 2.70.  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 --docdir=/usr/share/doc/ruby-2.7.2 --htmldir=/usr/share/doc/ruby-2.7.2/html --libdir=/usr/lib64 --program-suffix=27 --with-soname=ruby27 --with-readline-dir=/usr --enable-shared --enable-pthread --disable-rpath --with-out-ext=,dbm,tk --without-jemalloc --disable-jit-support --disable-socks --disable-dtrace --disable-install-doc --enable-ipv6 --disable-static --disable-install-static-library --without-static-linked-ext --disable-debug --with-lookup-order-hack=INET --enable-option-checking=no
