pkg install command extracts package source in temporal directory and 
execute ./configure make and install
after command finished the temporal directory is deleted and you cannot see 
config.log.

To see config.log, the following procedure is required.

1. Download struct source tar ball (current version 1.0.14)
from 
https://octave.sourceforge.io/packages.php
struct => download

2. extract tar ball to the directory that you want (e.g ~/struct )

3. start octave

4. change directory <extracted directory>/struct-1.0.14/src
(e.g. cd ~/struct/struct-1.0.14/src)

5. From octave prompt, execute bash
system bash

You can see bash prompt.

6. execute configure
./configure

Perhaps configure fails.

You can see the config.log file.
