Hi Ralf,
I try to copy with std::copy my data into the indirect array:
std::vector<std::size_t> data(....);
std::sort(data.begin(), std::endl(),....);
ublas::indirect_array<> l_idx(data.size());
std::copy(data.begin(), data.end(), l_idx.begin());
I get the error in stl_algobase.h "assignment of read-only location"
I can copy the data with a for-loop, but I would prefere std::copy
Thanks for help
Phil
