Включение Nvidia в nvapi.h вызывает ошибки компиляции

Question

Включение Nvidia в nvapi.h вызывает ошибки компиляции

Я пытаюсь использовать NVIDIA nvapiи у меня есть ошибки компиляции, которые я не до конца понимаю. Возможно, я использую не тот компилятор?

#include "nvapi.h"
#include <iostream>

int main()
{
    printf("Hello nvapi!");
    return 0;
}

Компиляция:g++ nvapi_hello.cpp

Вывод (усеченный, потому что он был слишком длинным):

Решение

Похоже, что файлы заголовков, представленные в API NVIDIA, не совместимы с g++Компилятор GCC. Поэтому я решил использовать Microsoft C/C++ x64 компилятор. я использовал CMake (v3.5.2) для создания решения Visual Studio 2010, и это работало нормально после того, как я поиграл CMakeLists.txt файл.

Это содержание моего CMakeLists.txt:

cmake_minimum_required(VERSION 3.5)
include_directories(3rdparty)
link_directories(3rdparty/amd64)
add_executable(nvapi_test nvapi_hello.cpp)
target_link_libraries(nvapi_test nvapi64.lib)

И 3rdparty каталог содержит amd64 папка где nvapi64.lib есть, а также NVAPI *.h а также *.c файлы.

Также, как упоминалось в комментариях к моему вопросу (@RichardCritten), мне пришлось добавить #include <Windows.h> на вершине моего .cpp файл для его правильной компиляции.

Я нашел ответ, который объясняет, что эти переменные созданы с #define в файле nvapi_lite_salstart.h а затем неопределенный с помощью #undef в файле nvapi_lite_salend.h который вызывается в начале и в конце соответственно в каждом из файлов заголовка, как указано здесь в начале nvapi.h:

#include"nvapi_lite_salstart.h" //Remove this line
#include"nvapi_lite_common.h"
#include"nvapi_lite_sli.h"
#include"nvapi_lite_surround.h"
#include"nvapi_lite_stereo.h"
#include"nvapi_lite_d3dext.h"
#include"nvapi_lite_salstart.h" //Add this line to fix the errors

Как видите, похоже, что файл "salstart" просто нужно переместить в конец списка, потому что по какой-то причине он неверно вверху. Не уверен, почему это работает должным образом в Visual Studio (это происходит без внесения вышеуказанных изменений), но это по крайней мере исправило эти ошибки в MinGW; однако файл скомпилированной библиотеки, предоставленный nVidia (либо nvapi.lib или же nvapi64.lib) НЕ совместим с MinGW, поэтому вы вынуждены использовать MS Visual Studio.
