Error compiling 1.11.X with LLVM #256
Comments

The incomplete type seems to be Either musl lacks std::pair or it has some bugs, I don't know. I do not officially support musl.. too niche.. and too incomplete. If you can figure out a patch to fix this, it's welcome but I lack the time to support this. Sorry man. |
|
Thanks, but if i change the step to reproduce to |
|
Hmm. Ah, interesting. Well one big difference is that 1.11.0 switched the compiler standard to use C++20. Maybe there's something weird/out of spec with musl and C++20? |
|
Hmm. I wonder if this error might be related to llvm trying to use libstcd++ (gcc's C++ headers and lib) rather than its own libc++ (clang C++ headers and lib)... from the paths in the above error log it looks like that might be what's going on. And it could be that with language standard c++17 it "just worked" but with c++20 somehow that trips things up. You may have to figure out what flags to use to use the llvm/clang headers? No idea man.. this is kind of beyond the scope of my time commitments right now.. but if you do figure it out, patches welcome. |
|
It's out of my scope too, but I found some possible related problems. Maybe someone could find the issues helpful. llvm/llvm-project#62166 llvm/llvm-project#59966 llvm/llvm-project#59292 |

Oh I see I need to use alpine to reproduce. I will try to do so now.. and maybe come up with a clever solution but.. this really is not something I wanted to support. Use a real libc man wth. musl is anemic and buggy last I checked. |
|
Ok, I was able to reproduce on alpine. This is definitely an issue with alpine's environment. Something is not kosher in what is going on with clang++ 17 and alpine. I don't like that it's using g++'s C++ headers rather than clang's, for start. That is suspicious. Also doubly so that it's using musl. I have definitely used clang-17 before without issue. In fact, I just tried it now on a different non-alpine box with clang-17 and it compiled fine. |

This is a linking error. So.. it got to the link phase. At least it compiled! Looks like it's having trouble linking to Qt lib. You started from a fresh build dir, yes? Idk what to tell you man. This is not a problem with the Fulcrum codebase per se. This is some issue with linking to Qt and I don't have the time or energy to troubleshoot this further. Use gcc on Linux. Gcc these days is more feature-complete anyway. |
|
It also failed to link to rocksdb. . . idk sometimes C++ libs compiled with gcc don't play nice with clang. If you want to use clang looks like you either have to get to the bottom of this or rebuild the world with clang.. sorry. This is beyond my paygrade. |

Seems to be something related to an incomplete type being used in a standard library container, specifically
std::vector<std::pair<QByteArray, (anonymous namespace)::Container>>located onsrc/Json/Json_Parser.cpp.Compile just fine with
