obs-studio專案下載下來后，用CMake生成VS2017工程專案，運行編譯時，報錯，都是iso_volatile_loadXX相關
網上也沒有找到相關資料，求各位大佬幫忙看看該怎么處理

沒有鏈接相應的庫吧uj5u.com熱心網友回復：

我在cmake的時候，確實有些庫沒有鏈接，
下面是CMAKE編譯的內容，不識別iso_volatile_load32，是哪個庫？

Intrinsic Functions On Alpha - OverviewIntrinsic functions (also known as intrinsics) are function calls that the compiler resolves directly, by generating code, rather than by calling an external function. The Alpha version of the compiler supports a number of intrinsics.
With all intrinsics, you must explicitly enable the intrinsic before calling it, by using it with the /Oi compiler option or the intrinsic pragma. The general syntax for using this pragma is:
#pragma intrinsic( intrinsic-name )
For example, to enable the use of the _InterlockedIncrement intrinsic, include a pragma as shown, along with the declaration of the function:
long _InterlockedIncrement(long *);
#pragma intrinsic(_InterlockedIncrement)
The intrinsic functions listed in the following sections correspond one-for-one with existing instructions or PAL calls in the Alpha architecture. These functions assume that the following type definitions apply:
typedef signed _ _int 64 int 64;
typedef unsigned _ _int 64 uint64;
Please note that some intrinsics may only be executed in privileged context; for example, the _ _PAL_HALT intrinsic may only be successfully executed in kernel mode. For additional information, please consult the Alpha Architecture Reference Manual or Alpha Calling Standard (contained in Visual C++ Online Documentation).

試過了，還是沒用，e:\github_code\obs-studio-master\libobs\util\threading-windows.h(67): warning C4013: “__iso_volatile_load32”未定義；假設外部回傳 int (編譯源檔案 E:\github_code\obs-studio-master\libobs\callback\signal.c)
uj5u.com熱心網友回復：
#include <intrin.h>
uj5u.com熱心網友回復：
在參考“__iso_volatile_load32”的頁面，我看過了，有intrin.h這個頭檔案，intrin.h里面包含了intrin0.h頭檔案，“__iso_volatile_load32”在intrin0.h頭檔案里面宣告定義的。
我覺得應該是obs-studio用cmake生成vs2017工程檔案的時候，少了哪些設定造成的
論壇里面有對obs-studio二次開發的大佬沒有？

** __MACHINEARM_ARM64 : ARM and ARM64 only你的CPU不是或沒設定為ARM and ARM64
uj5u.com熱心網友回復：
應該不是ARM的，但生成的工程不應該自動識別嗎？用CMAKE生成工程前，cmake里面沒看到哪里設定ARM的uj5u.com熱心網友回復：

謝謝你的回答，但問題還是存在

在#include <threading-windows.h>之前沒有#include <intrin.h>uj5u.com熱心網友回復：
threading-windows.h里面就有#include <intrin.h>
