Как мы видим, это связано с заголовочными файлами, которые идут с установкой, что заставляет меня поверить, что ошибки как-то связаны с компиляторами.
В руководстве по Compute Cpp говорится следующее: «В вашей установке Visual Studio могут отсутствовать необходимые инструменты и конфигурации C ++, вы можете проверить это, изменив вашу установку из программ добавления / удаления». Интересно, какие инструменты и конфигурации мне не хватало при установке Visual Studio 2015. https://developer.codeplay.com/products/computecpp/ce/guides/platform-support/targeting-windows
Редактировать: После добавления #include <cstdint>, как было предложено, все эти ошибки были устранены. Сборка стала успешной. Однако при выполнении я получил следующие ошибки:
