Re: [Boost-users] boost/numeric/ublas/matrix_sparse.hpp does not play well with RICE

I posted earlier today, and I think now that the problem might not be RICE at all. I just tried to compile something that I *know* should compile properly, which does not use RICE, and it didn't work with a *different* boost library (in this case ). I'm not really sure how to troubleshoot this. I know I upgraded recently from boost 1.41 to 1.43, but I can't see how that would be the issue. Perhaps I somehow have multiple versions of boost hidden here and there and it's trying to use the headers from one but libraries from another? For example, compiling this file: #include int main() { return 0; } Gives these errors: $ g++ -I. -I. -I/usr/lib/ruby/1.8/i486-linux -I. -D_FILE_OFFSET_BITS=64 -fPIC -fno-strict-aliasing -g -g -O2 -fPIC -Wall -g -c main.cppIn file included from /usr/local/include/boost/unordered/detail/equivalent.hpp:11, from /usr/local/include/boost/unordered/unordered_map.hpp:19, from /usr/local/include/boost/unordered_map.hpp:16, from main.cpp:4: /usr/local/include/boost/unordered/detail/extract_key.hpp:31: error: template argument required for ‘struct set_extractor’ /usr/local/include/boost/unordered/detail/extract_key.hpp:77: error: template argument required for ‘struct map_extractor’ In file included from /usr/local/include/boost/unordered/unordered_map.hpp:19, from /usr/local/include/boost/unordered_map.hpp:16, from main.cpp:4: /usr/local/include/boost/unordered/detail/equivalent.hpp:19: error: wrong number of template arguments (4, should be 1) /usr/local/include/boost/unordered/detail/fwd.hpp:661: error: provided for ‘template<class T> class boost::unordered_detail::hash_equivalent_table’ (continues for a few pages) It does not do this with all boost libraries. I have no problems with lexical_cast. Grateful for any assistance, John On Thu, May 20, 2010 at 11:32 AM, John O. Woods wrote:

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

int main() { return 0; }

So does this:

#include

int main() { return 0; }

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

$ make g++ -I. -I. -I/usr/lib/ruby/1.8/i486-linux -I. -D_FILE_OFFSET_BITS=64 -I/usr/lib/ruby/gems/1.8/gems/rice-1.3.2/ruby/lib/include -fPIC -fno-strict-aliasing -g -g -O2 -fPIC -Wall -g -c main.cpp In file included from /usr/local/include/boost/numeric/ublas/storage_sparse.hpp:23, from /usr/local/include/boost/numeric/ublas/vector_sparse.hpp:16, from /usr/local/include/boost/numeric/ublas/matrix_sparse.hpp:16, from main.cpp:5: /usr/local/include/boost/numeric/ublas/storage.hpp:60: error: expected primary-expression before ‘)’ token /usr/local/include/boost/numeric/ublas/storage.hpp:65: error: expected primary-expression before ‘)’ token /usr/local/include/boost/numeric/ublas/storage.hpp:79: error: expected primary-expression before ‘)’ token /usr/local/include/boost/numeric/ublas/storage.hpp: In member function ‘typename ALLOC::size_type boost::numeric::ublas::unbounded_array::max_size() const’: /usr/local/include/boost/numeric/ublas/storage.hpp:174: error: expected primary-expression before ‘)’ token /usr/local/include/boost/numeric/ublas/storage.hpp:174: error: expected ‘;’ before ‘ruby_xmalloc’ /usr/local/include/boost/numeric/ublas/storage.hpp:174: error: expected primary-expression before ‘)’ token /usr/local/include/boost/numeric/ublas/storage.hpp: In member function ‘typename ALLOC::size_type boost::numeric::ublas::bounded_array::max_size() const’: /usr/local/include/boost/numeric/ublas/storage.hpp:357: error: expected primary-expression before ‘)’ token /usr/local/include/boost/numeric/ublas/storage.hpp:357: error: expected ‘;’ before ‘ruby_xmalloc’ /usr/local/include/boost/numeric/ublas/storage.hpp:357: error: expected primary-expression before ‘)’ token In file included from /usr/local/include/boost/numeric/ublas/vector_sparse.hpp:16, from /usr/local/include/boost/numeric/ublas/matrix_sparse.hpp:16, from main.cpp:5: /usr/local/include/boost/numeric/ublas/storage_sparse.hpp: At global scope: /usr/local/include/boost/numeric/ublas/storage_sparse.hpp:240: error: expected primary-expression before ‘)’ token make: *** [main.o] Error 1

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')
