Here, by the way, is the original thread, which I could not figure out how to quote in my message: https://lists.llvm.org/pipermail/llvm-dev/2020-May/141444.html

Hi Emmanuel and Lang,

I am tuning in to this thread several months late, because I am just now trying to port our ORC-based application to Windows, and I am running into all the same problems that Emmanuel ran into. To avoid unresolved symbols I have had to compile JIT modules with -DDLL; I have had to export RTTI-related symbols explicitly with the same trick that Emmanuel found; and now I have multiple definitions of ??7exception at std@@6B@, like Emmanuel. I see this bug has not been fixed, so my question is mostly for Emmanuel: have you found a workaround? I don't know exactly when this symbol is generated, but I have C++ modules that cannot be JIT compiled as a result... Geoff -------------- next part -------------- An HTML attachment was scrubbed...
