使用Mingw-w64构建"英特尔线程构建块"失败

Question

我正在将Mingw-w64与gcc 10.2一起使用，并尝试在MSYS2控制台上编译"英特尔线程构建块"。我之前已经成功地使用了旧版本的构建脚本，但新版本带有标签"；v2021.2.0"；仅提供CMake内部版本。

我通过在MSYS2控制台上运行以下脚本来构建：

#!/bin/bash
TBB_DIR=/c/Libraries/TBB
PARALLEL_PROCESSES=1
echo
echo Building Tbb...
echo
rm -rf $TBB_DIR/Build
mkdir $TBB_DIR/Build
cd $TBB_DIR/Build
cmake -DCMAKE_BUILD_TYPE="Release" -S "$TBB_DIR" -B "$TBB_DIR/Build" -G "MSYS Makefiles" -DCMAKE_INSTALL_PREFIX="$TBB_DIR/Install" -DTBB_STRICT=False -DTBB_TEST=False
cd $TBB_DIR/Build
mingw32-make -j $PARALLEL_PROCESSES install

构建失败，错误为：

In file included from C:/Libraries/TBB/include/oneapi/tbb/detail/_utils.h:26,
from C:/Libraries/TBB/src/tbb/allocator.cpp:21:
C:/Libraries/TBB/include/oneapi/tbb/detail/_machine.h:241:56: error: '_MCW_DN' was not declared in this scope

为什么会出现这种情况？是否不支持Mingw-w64？或者我做错了什么？

我可以在Windows上用MinGW-w64构建TBB 2020.0，如下所示(无需CMake(：

#ARCH=ia32
ARCH=intel64
mingw32-make compiler=gcc arch=$ARCH runtime=mingw tbb tbbmalloc CPLUS="g++ -static-libstdc++ -static-libgcc"
