w64-Mingw LLVMSupport.a：对 __imp_* 的未定义引用

Question

试图将某些东西链接到 LLVMSupport 的非常奇怪的错误：

C:/projects/builds/LLVM-3.3/lib/../lib/libLLVMsupport.a(Signals.cpp.obj):Signals.cpp:(.text+0x524): undefined reference to `__imp_SymSetOptions'
C:/projects/builds/LLVM-3.3/lib/../lib/libLLVMsupport.a(Signals.cpp.obj):Signals.cpp:(.text+0x542): undefined reference to `__imp_SymInitialize'

dbghelp.dll 中有类似名称的函数 http://msdn.microsoft.com/en-us/library/windows/desktop/ms681327%28v=vs.85%29.aspx

但是链接到这个库并不能修复它。

我一直在处理这个问题......如何解决它？

注意： 我已经用 64 位的 cmake + mingw64 编译了带有 SEH 的 llvm，并带有一个补丁来强制进行正确的 EH 方法测试。

那我找不到这些符号用在什么地方了……

MinGW 有自己的实现，只是在命令的末尾（顺序很重要）添加 -limagehlp
