LogTo does not work on HPC-GAP

[mth162]

Build HPC-GAP:

./configure --enable-hpcgap make

Then run it:

./bin/gap.sh LogTo("/path/to/logfile")

then enter various GAP statements ...

Observed behaviour

/path/to/logfile is created but interaction not captured (unless if there is an error--e.g. syntax error)

Expected behaviour

Normal interaction should be captured.

Note: if I do exactly same as before, but without the '--enable-hpcgap' option (i.e. building 'normal' GAP) then LogTo works.

Yes, this is a side effect of how the REPL is implemented in HPC-GAP. I don't think there is an easy way to fix this. I see little chance that anyone will work on this, I am afraid, sorry.
