我正在尝试从threadingbuildingblocks编译 TBB 源文件。

我已经在 stackoverflow 上尝试了所有可用的解决方案，但它们都不起作用。我得到的错误是：

请让我知道我是否应该在此处添加其他文件以让您了解问题。

我的问题的解决方案是它试图从路径加载库 

 -L/cygdrive/d/Android/NDK/platforms/android-9/arch-x86/usr/lib 
 -L/cygdrive/d/Android/NDK/sources/cxx-stl/gnu-libstdc++/4.6/libs/x86

这确实是我驱动器上的正确位置，但 Windows 上的路径不正确。

我不得不将这部分代码用 Windows 可理解的路径文本硬编码为：

-LD:/Android/NDK/platforms/android-9/arch-x86/usr/lib 
-LD:/Android/NDK/sources/cxx-stl/gnu-libstdc++/4.6/libs/x86

找不到多个库。尝试找出这些库在您的系统上的位置。

在 makefile 中，将此路径添加到 LD_FLAGS 以供链接器搜索：

-L$(NDK_ROOT)/platforms/android-9/arch-x86/usr/lib/

首先，检查是否可以在那里找到所需的库（例如 libm.so）

如果没有，请尝试找出它们是否在您系统的其他位置。在 Linux 上，libdl.so、libm.so 等可以在 /usr/lib64（32 位系统上的 /usr/lib）中找到。如果找到它们，请添加到 LDFLAGS 的路径，就像上面的路径一样：

-L/path/to/libs
