我正在尝试使用 ICU v4.8.1 编译 ICU v4.8.1。 adobe.com/technologies/alchemy/" rel="nofollow">Alchemy,但遇到了 LLVM 问题:

什么样的代码会导致链接器中出现此问题?这似乎与强制转换有关(“left-hand-side-cast != right-hand-side-cast”)。我不会修改 ICU 代码以使其编译,但我不确定要修改什么。

What kind of code leads to this problem in the linker? It seems to have something to do with casting ("left-hand-side-cast != right-hand-side-cast"). I'm not above modifying the ICU code to make it compile, but I'm not sure what to modify.

可以是任意数量的事情。可能的原因是错误的 llvm IR 被馈送到链接器中。最好的选择是与 Alchemy 人员交谈,看看他们在做什么,并让他们进行调试。

Could be any number of things. The likely cause is bad llvm IR being fed into the linker. Your best bet is to talk to the Alchemy guys and see what they're doing and get them to debug it.
