Побудова 64-розрядної програми на 32-бітній Ubuntu 12.04

Я хочу зробити додаток на 64 cpp в 32-бітний Ubuntu. Я отримую такі помилки під час компіляції:

Я думаю, що для цього є виправлення, завантаживши відповідне libcсередовище 64b . Це так? Як мені діяти?

Відповідно до індексу пакета , libc6-dev-amd64містить bits/predefs.h(ваші помилки стосуються того, що файл заголовка відсутній). Тож встановіть його:

sudo apt-get install libc6-dev-amd64
