 ius | So I just tried that, doesn't seem to have any effect. In many hours of Googling I also discovered builtins.trace, adding that to print the build/host/target triplet shows it's being evaluated 3 times: {x64, x64, x64}; {x64, x64, x64}; {x64, x64, ppc} | 20:22:43 |

 symphorien | there are more handy functions in lib.debug | 14:54:19 |
| ius | Ah excellent, at the very least my trace printing is less awkward now (just trace won't eval a sequence), traceSeq does | 15:53:23 |
| ius | Maybe I need to approach this from the other end and instead of patching patchelf, try to modify the part where stdenv includes it? | 16:33:41 |
| ius | Looking into stdenv I notice there are some other peculiarities (although I hardly understand how it works in the first place)
55 mipsel-linux = stagesLinux;
56 powerpc-linux = /* stagesLinux */ stagesNative;
57 powerpc64-linux = stagesLinux;
powerpc is the odd one out for some reason

 Alyssa Ross | sternenseemann: I think I found the commit that changed it... | 12:29:28 |
 sterni | Alyssa Ross: in llvm? | 13:07:08 |
| Alyssa Ross | yeah | 13:07:13 |
| sterni | interesting! | 13:07:20 |
| Alyssa Ross | I'm going to need to find it again now... | 13:07:30 |
| sterni | I'm intrigued now what the actual cause is because the only explanation that would make sense to me is that the terminfo dependency is new in LLVM 12 | 13:08:11 |
| Alyssa Ross | nope, it was a cmake refactor | 13:08:33 |
| sterni | very strange | 13:08:47 |
| Alyssa Ross | I assume the change to passing absolute path to the linker was accidental | 13:08:50 |
| Alyssa Ross | sternenseemann: 3c7bfbd6831b is where it starting trying to link with absolute host ncurses path | 13:14:33 |
| Alyssa Ross | I haven't determined why it stopped finding ncurses by name though | 13:15:19 |
| sterni | ah real shame that meta.platforms does only accept system strings | 13:43:13 |
| sterni | * a real shame that meta.platforms does only accept system strings | 13:43:17 |
| sterni | we probably want to have the unsupported platform predicate | 13:47:12 |

| sterni | maybe its optional and it doesn't find it for the cross case and ignores it | 14:23:16 |
| sterni | and in llvm 12 it does discover it, but the wrong one, possibly? | 14:23:26 |
| ius | Pff, finally managed to override patchelf the way I wanted (i.e. for cross only): I ended up prepending it to extraNativeBuildInputs in stdenv/cross. Original patchelf is still dragged in somehow, but ends up further down in PATH | 17:55:06 |
