Hello again,
I have collected Octave from CVS on 8 December 2000.
The ./configure is complaining about my gperf, and ultimately c++ complains
about lex.cc in a way which looks related.
I have installed a new gperf; it says
bash:> gperf --version
GNU gperf 2.7.2
./configure is saying
checking for gperf... gperf
configure: warning: I found gperf, but it does not support all of
the following options: -t -C -D -E -G -L ANSI-C -H -N;
you need gperf 2.7 or a more recent version
I have started to search out an explanation: I think ./configure is
doing something like:
#! /bin/sh
echo "%{
%}
%%
" | /usr/local/bin/gperf -t -C -D -E -G -L ANSI-C -H octave_kw_hash -N
octave_kw_lookup
which is giving the error message
Empty input key is not allowed.
To recognize an empty input key, your code should check for
len == 0 before calling the gperf generated lookup function.
Can you give any advice?
Thanks,
John
