Ошибка компиляции C++ в Linux

Ниже приведен код, который отлично компилируется на eclipse. Это полностью функциональная, простая программа, которая печатает адреса памяти.Ошибка компиляции C++ в Linux

Может кто-нибудь сказать мне, что я делаю неправильно?

нет причин бросать результаты вашего malloc. компилятор делает это неявно. Также вы всегда должны проверять свое возвращаемое значение из malloc для отрицательного и немедленно выходить, если есть ошибка. –

Ну, вы можете видеть, что большинство ошибок на самом деле являются предупреждениями, которые легко понятны и легко исправлены (я надеюсь). Вы только фактическая ошибка для меня новая, но эта ссылка может помочь, http://stackoverflow.com/questions/329059/what-is-gxx-personality-v0-for. – john

Вы действительно должны набрать 'man printf' и посмотреть, что именно означает'% 10lu'. Вы в основном предполагаете, что указатель имеет тот же размер, что и 'long unsigned int'. Вместо этого попробуйте '% p'. Или просто используйте iostreams. – kccqzy

Расширение файла CPP, поэтому GCC считает, что это файл C++. Однако вы пытаетесь установить связь с GCC, который не знает, как связать программы на C++. Используйте g ++ для командной строки или переименуйте файл в файл .c.

Я попробовал g ++ file.cpp -lpthread случилась – NewFile

Вы уверены? Все эти предупреждения будут сохраняться, но фактические ошибки - это ошибки ссылок, которые должны быть исправлены. –

Что вы подразумеваете под ссылками ошибок? theres только один файл, поэтому theres ничего другого, котор нужно связать дальше ... правильно? – NewFile

Вы хотите печатать адреса памяти, они указатели. Тоны форматирования printf ожидают целые числа. Вы должны отнести их к целым числам, поэтому расширьте & pointerVariable to (unsigned long int) & pointerVariable.
