Hi there,

Cross-posted this to the RICE listserv, but they cannot reproduce. I can reproduce it on karmic and lucid (ubuntu), separate machines, in boost 1.43.0. RICE is a C++ interface for Ruby (not unlike boost python).

If I include boost numeric ublas matrix_sparse and either rice/Data_Type.hpp or rice/Constructor.hpp, I get a lot of errors -- even if I do nothing with them.

For example, this works:

#include <boost/numeric/ublas/matrix_sparse.hpp>

int main() {
  return 0;
}


So does this:

#include <rice/Data_Type.hpp>

int main() {
  return 0;
}

But if I put both #includes in, it gives the following errors:

ruby_xmalloc does not seem to exist in that file, so I gather it's having some kind of syntax hiccup that is leaking into later #includes.

Here are other relevant details:

$ sudo gem list --local |grep rice
rice (1.3.2, 1.3.1)

I seem to get the same bug with both boost 1.41 and boost 1.43, though sometimes I have trouble telling which one I'm including.

Should this be a bug report, or am I missing something stupid?

(I'd be eternally grateful if you'd reply to me as well as to the list.)

Thanks so much,
John


PS: extconf.rb below. Works fine for other projects, as long as I don't use matrix_sparse.

require 'rubygems'
require 'mkmf-rice'

dir_config("boost")

have_library("stdc++")
have_library("boost")
have_library("boost_filesystem")
if RUBY_VERSION =~ /1.9/ then
  $CPPFLAGS += " -DRUBY_19"
end

create_makefile('main')
