Thank goodness for that!

Went to the website suggested and did as suggested (CFLAGS=-no-pie
./configure --enable-dynarec --enable-debug)and got a response

too many arguments

but unfortunately did not save the output.

I then tried without the configuration options (i.e. just the
CFLAGS=-no-pie) and was returned to

zed@zed-pc:~/rpcemu-0.8.15$ CFLAGS=-no-pie

I then started again and got the following output

zed@zed-pc:~$ cd /home/zed/rpcemu-0.8.15
zed@zed-pc:~/rpcemu-0.8.15$ CFLAGS=-no-pie ./configure --enable-dynarec
--enable-debug
bash: ./configure: No such file or directory
zed@zed-pc:~/rpcemu-0.8.15$ ./configure --enable-dynarec --enable-debug
bash: ./configure: No such file or directory
zed@zed-pc:~/rpcemu-0.8.15$

Would the fact that I did

zed@zed-pc:~/rpcemu-0.8.15$ CFLAGS=-no-pie

have led to the output of No such file or directory?

I have checked and found that doing a cd <directory path> works on every
other Directory I've tried, other than /rpcemu-0.8.15 one.

As an aside, I have Linux Mint v18.2 Mate installed in another partition.
I booted into this and had no difficulty in installing rpcemu-0.8.15,
other than that the window which opened was very small and I could not
adjust it and there was only one screen resolution available. I was able
to run !Draw and Paint! without problem, but could not open a floppy disc
containing !Drawfiles. Just got an error asking whether the disc was
formatted! That could be because when I upgraded this desktop a few years
ago, I've never checked whether the floppy disc drive was connected.

Again, thank you for staying with this. All suggestions welcome.

Regards

David
