Comment 18 for bug 1426110

The result:

pm@raspberrypi ~/Desktop/hplip-3.15.2 $ ./configure --prefix=/usr

./configure: line 2235: config.log: Permission denied
./configure: line 2245: config.log: Permission denied

pm@raspberrypi ~/Desktop/hplip-3.15.2 $ ls -l config.log
ls: cannot access config.log: No such file or directory
pm@raspberrypi ~/Desktop/hplip-3.15.2 $

I still have the old config .log file on the desktop?

The config file line 2229 follows.
eval ac_res=\$$3
        { $as_echo "$as_me:${as_lineno-$LINENO}: result: $ac_res" >&5
$as_echo "$ac_res" >&6; }
  eval $as_lineno_stack; ${as_lineno_stack:+:} unset as_lineno

} # ac_fn_c_check_type
cat >config.log <<_ACEOF
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by HP Linux Imaging and Printing $as_me 3.15.2, which was
generated by GNU Autoconf 2.68. Invocation command line was

  $ $0 $@

_ACEOF
exec 5>>config.log
