Typelists

What is the status of typelist support in boost? I read through a backlog of email in the archives but the last ones are from ~2002. Grepping through the source of 1.31.0 for (typelist | type_list) reveals some in the detail namespace for python, but that's all.

uBLAS lapack bindings
by Daniel L Elliott 07 Oct '04

07 Oct '04

Hello, I have a question about using uBLAS/LAPACK bindings on AIX 5.1 and VA6. I am doing something like the following: matrix<double> matrixTwo(200,200); identity_matrix<double> identMatrix = identity_matrix<double>(200); int inverseInfo = gesv(matrixTwo,identMatrix); I am getting the following errors: line 102.36: 1540-0130 (S) "matrix_traits<boost::numeric::ublas::matrix<double,boost::numeric::ublas::row_major,boost::numeric::ublas::unbounded_array<double,std::a\ llocator<double> > > >::size1" is not declared "/npd/delliott/boost/numeric/bindings/traits/matrix_traits.hpp", line 102.7: 1540-0700 (I) The previous message was produced while processing "boost::numeric::bindings::traits::matrix_size1<boost::numeric::ublas::matrix<double,boost::numeric::ublas::row_major,boost::numeric::ublas::unbounded_array<double,std::allocator<double> > > >(matrix<double,boost::numeric::ublas::row_major,boost::numeric::ublas::unbounded_array<double,std::allocator<double> > > &)".

As I understand it, I can simply pass the uBLAS matrix types and the traits/lapack .hpp files will take care of the rest. Any light that could be shed upon this subject would be of great assistance. By the way, I would have happily send this to uBLAS-dev, but have not been admitted yet :( Thank you, Dan

After I have switched that to the explicit "using" statements I could also switch back to your default "user.hpp". Perhaps I can ask one more question about this strange behaviour, just because I want to understand why: I try to use my own string class, which is inherited from std::string. Defining "VC6_STUPID_BEHAVIOUR" in the example code below compile and run the code successfuly, using the expanded name leads to following compiler error: error C2614: 'MyCString' : illegal member initialization: 'string' is not a base or member You know WHY??? Also because of the same compiler error in VC6 or is there something else wrong. On Solaris and HP-UX it works fine in every combination. // vvvvvvvvvvvvvvv snipp vvvvvvvvvvvvvvvv #include <string> #include <iostream> #ifdef VC6_STUPID_BEHAVIOUR using std::string; # define std_string string #else # define std_string std::string #endif class MyCString : public std_string { public: MyCString(const char *s_); : std_string(s_) { std::cout << "\"" << *this << "\"" << std::endl; }; }; int main (int argc, char *argv[]) { MyCString s(argv[0]); return 0; } // ^^^^^^^^^^^^ snipp ^^^^^^^^^^^^

boost install with gentoo issue?
by dave＠superelite.net 06 Oct '04

06 Oct '04

Well, more likely my mistake, ive been up awhile.. I installed the boost libs onto my gentoo machine with emerge. I then added -lboost_regex to my linker flags..thats it. When I run my app, it hangs, I think when waiting on pulling data of off a UDP socket. Though I cant tell, I'm about to crash and its been one of those days. But I do know everything is back to normal when I take -lboost_regex out of the flags again. I know I'm awfully vague due to lazy/tiredness, but does this ring a bell with anyone? I've installed boost the traditional way (bjam) on other linux distros before without any issue, but ive never tried emerge before. I dont know if this has something to do with it, or i am somehow missing something really obvious.. Thanks for bearing with me, Dave

uBLAS LAPACK bindings
by Daniel L Elliott 06 Oct '04

06 Oct '04

Hello, Are the uBLAS LAPACK bindings for general matrices or for any type of matrix? Do they have to use a particular type of storage? This is how it appears in the code. Would anyone like to talk about how other types of matrices might be used? Thank you, Dan

uBLAS problem under Borland C++builder
by 徐亮 05 Oct '04

05 Oct '04

Hi Boost people I'm starting with uBLAS matrix class under Borland C++ builder. I copied a sample from boost document and complied it. There are always mistakes in "traits.hpp". I tried again in VC and no problem occured. I just wonder what's wrong with BC. I have copied the boost dir into BC's Include dir and have added it in Project->Options->Directories. Here's my copied code: #include <boost/numeric/ublas/matrix.hpp> #include <boost/numeric/ublas/io.hpp> int main () { using namespace boost::numeric::ublas; matrix<double> m (3, 3); for (unsigned i = 0; i < m.size1 (); ++ i) for (unsigned j = 0; j < m.size2 (); ++ j) m (i, j) = 3 * i + j; std::cout << m << std::endl; } Thanx
