I m trying to compile a small piece of code using boost::accumulators. I have compile problems :

fatal error C1083: Impossible d'ouvrir le fichier include : 'boost/fusion/sequence/adapted/mpl.hpp' : No such file or directory

Looks like that file got moved. That #include should now be . It's already fixed in svn trunk. I'll try to package a new download for the file vault.

I've updated accumulators.zip in the file vault. Let me know if you notice any other problems. Thanks, -- Eric Niebler Boost Consulting www.boost-consulting.com

Hi, I'm learning about multi_arrays and have not been able to find much info about different ways of initializing them. In particular I'm interested in initializing a multi_array in the same way I can init a basic C/C++ array:

int array_2d[3][3] = { {1,2,3}, {2,3,4}, {3,4,5} };

That is impossible because multi_array is not an aggregate.

When I declare an analogous multi_array, the compiler (VC++ 8.0) complains about the third line:

typedef boost::multi_array< int, 2 > int_2d_array_t; boost::array< int_2d_array_t::index, 2 > shape = {{ 3, 3 }};

int_2d_array_t A(shape) = { {1,2,3}, {2,3,4}, {3,4,5} }; // error C2143: syntax error : missing ';' before '='

The online documentation only mentions initialization of individual elements (A[0][0][0] = 4;), but in doing it that way would be very tedious.

What alternatives are there?

Nothing really wonderful, I hate to say. I wish that Boost.Assign worked. The best I can come up with is: #include using boost::assign::list_of; int main() { boost::multi_array test(boost::extents[1][9]); int init[9] = { 1, 2, 3, 4, 5, 6, 7, 8, 9}; std::copy(&init[0], &init[0] + 9, test[0].begin()); boost::array shape = {3, 3}; test.reshape(shape); //test.reshape(boost::extents[3][3]); // doesn't compile } In Christ, Steven Watanabe

Thank you Eric,

I know there are 2 other headers causing problem.

With the current .zip in the vault? Or the older one?

However, instead of "hacking" the files from the vault, I choose, to checkout from the SVN repository, so I cannot remember the includes causing problems.

What's in the .zip now is a copy of what's in SVN. -- Eric Niebler Boost Consulting www.boost-consulting.com
