проблем при компилиране на програма с помощта на библиотека за усилване на регулярен израз

Опитах се да компилирам програма за усилване, която използваше библиотека с регулярни изрази за усилване на моя linux кутия. има всички необходими заглавки и библиотеки. Програмата отказва да компилира, хвърляйки огромно изхвърляне на шаблонен изход. Използвам следната команда, за да компилирам програмата.

Моля, посъветвайте как да поправите по-долу.

g++ regex.cc -I/usr/local/include/boost/ -L/usr/local/lib -lboost_regex -o regex

ето изхода на компилатора.

Отидете до файла regex.cc, ред 30 (regex.cc:30: екземпляр от тук) и се ВЗЯВАЙТЕ в него (кръстосана проверка с примери от документация, които работят), докато не стане ясно какво сте направили погрешно. Изглежда, че извиквате обратно() и празен() на нещо, което не поддържа тези операции. Като се има предвид [50] в края на тези съобщения за грешка [които също казват некласов тип], вероятно сте забравили да индексирате масив. (т.е. сте написали array.empty() вместо array[i].empty()).

грешка: искане за член '.....' в '......' често се причинява от използването на ., когато трябва да използвате - > или добавяне на () в декларация, когато не трябва, например:

TheClass myTheClass();

вместо

TheClass myTheClass;
