i,
i looked at previous posts on this topic. did not help, a suggestion would be appreciated:
installed atlas version 3.6.0-20.6
/usr/lib/atlas3-test runs just fine.
header cblas.h and clapack.h are in /usr/include/ which is by default in my include path.
Configuration: -I/usr/local/include/boost_1_34_1 -I/usr/local/include/boost-bindings -L/usr/lib/atlas -llapack -lblas
i'm trying to run the program:
#include
#include #include // #include namespace ublas = boost::numeric::ublas; namespace atlas = boost::numeric::bindings::atlas;
int main() { std::size_t n = 5; ublas::matrix<double> a(n, n); // fill matrix a
std::vector<int> ipiv (n); // pivot vector atlas::lu_factor (a, ipiv); // alias for getrf() atlas::lu_invert (a, ipiv); // alias for getri()
return 0; };
i get the error
