 rhelmot | has anyone tried cross building openblas recently? I'm running into an issue where gfortran is not looking for the right ld - it wants the non-prefixed version | 16:38:18 |
| rhelmot | I am 150-some commits deep into a dev branch tho so maybe this is nothing | 16:38:34 |
| rhelmot | sigh. this seems to be freebsd specific, as pkgsCross.aarch64-multiplatform.openblas builds fine even on my dev branch | 17:58:46 |
| rhelmot | many such cases | 17:58:48 |

 GenericNerdyUsername | trying to use crossPackages.riscv32-embedded.buildPackage.gcc and while it does produce binanries, it ignore my -march=rv32i arg, generating a binary with compressed instructions in it | 22:48:46 |
| GenericNerdyUsername | i have a reproducible setup, but its definitely not minimal | 22:49:08 |
| GenericNerdyUsername | does work with the 25.05 tag | 22:52:03 |
| GenericNerdyUsername | * does work with the 25.05 tag of nixpkgs | 22:53:12 |
| GenericNerdyUsername | nvm, its there in both, idk how i missed that | 23:10:35 |
| GenericNerdyUsername | ig i mustve mixed up versions the bug is there in 25.05 but not 24.11 | 23:20:41 |

 alexfmpe | John Ericson s1341 : non-prebuilt android builds fails early on with compiler-rt not finding pthreads.h
$ nix-build -A pkgsCross.aarch64-android.hello
...
/build/compiler-rt-src-19.1.7/compiler-rt/lib/builtins/os_version_check.c:287:10: fatal error: 'pthread.h' file not found
287 | #include <pthread.h>
| ^~~~~~~~~~~
been this way for several months, any clue what that's about?
| 00:51:09 |
| alexfmpe | feels pretty similar to https://github.com/NixOS/nixpkgs/pull/344079 | 00:51:33 |

| alexfmpe | whereas aarch64-android-prebuilt works just fine for both hello and abseil-cpp
hmm all places consuming useAndroidPrebuilt seem to basically be doing gcc vs clang shenanigans | 00:59:49 |

ig i mustve mixed up versions the bug is there in 25.05 but not 24.11 Sounds bisectable? | 04:54:54 |
| GenericNerdyUsername | I did, breaking commit is 6b9c4bbe, which updated binutils from 2.43.1 -> 2.44 | 08:35:01 |
| GenericNerdyUsername | the most relevant changelog entry is that a bunch of new extensions are supported now | 08:36:17 |
| GenericNerdyUsername | Download flake.nix | 09:11:28 |
| GenericNerdyUsername | example | 09:11:33 |
| GenericNerdyUsername | new contains c.addi, old does not | 09:12:08 |
| GenericNerdyUsername | * the most relevant changelog entry is that a bunch of new riscv extensions are supported now | 09:17:26 |
 emily | I believe our wrapper strips -march by default? | 09:38:37 |
