У меня где-то утечка памяти, и, к сожалению, повторяющаяся тема, которая появляется о переполнении стека, не помогла;Я не совсем понимаю, как это происходит, так как я идентифицировал сомнительную строку из прогона gdb,
void read_data(std::string filename, number_type & parameter, number_type & n_part, number_type & mult){
std::ifstream infile(filename);
std::string line; // ERROR LINE
size_type counter_numbers = 0;
size_type counter_lines = 0;
while (infile)
{
std::getline(infile, line); // Read in current line
.
.
это то, где это показано в gdb: free (): неверный следующий размер (нормальный);при определении строки. Почему это случилось? Есть идеи?
спасибо, Дамир
Работает как
g++ -std=c++11 -I/users/damir/gsl/include/ -L/users/damir/gsl/lib/ -lgsl -lgslcblas -g -o MultB analysis_mult_b.cpp
