w64-Mingw LLVMSupport.a:对 __imp_* 的未定义引用 [英] w64-Mingw LLVMSupport.a : undefined reference to __imp_*

问题描述

试图将某些内容链接到 LLVMSupport 的非常奇怪的错误:

Quite weird bug trying to link something to LLVMSupport :

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'
C:/projects/builds/LLVM-3.3/lib/../lib/libLLVMsupport.a(Signals.cpp.obj):Signals.cpp:(.text+0x576): undefined reference to `__imp_SymGetModuleBase64'

dbghelp.dll 中存在同名函数http://msdn.microsoft.com/en-us/library/windows/desktop/ms681327%28v=vs.85%29.aspx

there are functions with similar names in dbghelp.dll 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.

but linking to this lib doesn't fix it.

这个问题我已经有一段时间了......如何解决它?

I've been on this problem for a while... How to fix it ?

注意:我已经用带有补丁的 SEH 和 64 位的 cmake + mingw64 编译了 llvm，以强制进行正确的 EH 方法测试.

Note : I've compiled llvm with cmake + mingw64 in 64 bits with SEH with a patch to force a correct EH method test.

然后我找不到这些符号在哪里使用...

Then I can't find where these symbols are used...

推荐答案

MinGW 自带实现，只是在命令的末尾添加 -limagehlp(顺序很重要)

MinGW comes with its own implementation, just to add -limagehlp at the end (the order matters) of the command
