[Plplot-devel] Configuration defaults

[Alan W. I. <ir...@be...>]

Could we have some discussion about what the configuration defaults should be?

I suspect most of the following are completely ignored at the moment with some
superseded by variables set up by autotools.  Shouldn't the ignored ones
be completely removed from configure.ac (including the configuration
printout at the end which prints them out even though they are
meaningless)?

with_debug=no
with_opt=yes
with_profile=no
with_shlib=yes
with_warn=no
with_dbmalloc=no
with_fseek=no
with_pkgdir=

Below are some additional options along with how I feel they should be
changed (or not).  I lean toward a default of with_double=yes, but if a
consensus forms to keep it the same I will go along.  I am not sure about
with_gcc=no.  It may be meaningless, and I don't know how it fits with the
autoconf way of setting compiler precedence. We might actually want
everybody to use gcc if they have it on their system. Is it time to turn
freetype on by default? That of course means it will only be used if
installed on the user's system. I think dyndrivers should be on by default.
I think the java interface is ready for extensive testing, but since that
testing hasn't occurred yet I lean toward no in that case, but probably yes
for the next release after this one.  I cannot judge octave that well, but
it has seemed stable to me for a long time so I think we should change it to
yes. gnome has problems so should continue to be no.  ntk seems stable to
me, so I lean toward yes.  It doesn't have all the features of tk, but on
the other hand that is true of the rest of our drivers as well.

with_double=no				yes?
with_gcc=no				?
with_freetype=no			yes?
enable_dyndrivers=no			yes
enable_java=no				no?
enable_octave=no			yes
enable_gnome=no				no
enable_ntk=no				yes?

Are there any other defaults that should be changed?
