 dramforever | no because this is inside unix_close_range | 14:05:37 |
| dramforever | #if defined(__linux__) || defined(__FreeBSD__)
static int unix_close_range(unsigned int first, unsigned int last, int flags)
{
# if !HAVE_CLOSE_RANGE
return syscall(SYS_close_range, first, last, (unsigned int) flags);
# else
return close_range(first, last, flags);
# endif
}
#endif

| matthewcroughan | ah yes, so it's like, musl doesn't have it | 14:06:25 |
| dramforever | implementing unix_close_range in terms of unix_close_range would be funny ... no it wouldn't work | 14:06:25 |
| matthewcroughan | so it tries to use SYS_close_range | 14:06:29 |
| dramforever | what musl version are you on again | 14:09:08 |
| matthewcroughan | 1.25, everything I'm doing is based on staging-next always | 14:09:48 |
| matthewcroughan | if I'm ever behind it's by a day or two | 14:09:55 |
| matthewcroughan | * 1.2.5, everything I'm doing is based on staging-next always | 14:10:11 |
| matthewcroughan | this is gnu-musl-llvm and musl-llvm though, I went back to musl native for testing, and I get a different error there in nix-expr | 14:10:55 |
| matthewcroughan | the error about close_range is from llvm/musl, so I guess it's about tha | 14:11:09 |
| matthewcroughan | * the error about close_range is from llvm/musl, so I guess it's about that | 14:11:11 |
| matthewcroughan | On native musl I get this from nix-expr

| dramforever | how on earth is it different on llvm and gcc | 14:14:32 |
| matthewcroughan | Maybe it just fails earlier, I had --keep-going on but didn't spot it | 14:14:50 |
| matthewcroughan | on native musl, I don't see nix-util in the graph even | 14:15:56 |
| matthewcroughan | 
Download image.png | 14:15:58 |
| dramforever | but we definitely build nix against musl right? | 14:16:12 |
| matthewcroughan | I guess it comes later, so yeah nix-expr fails first, before I can get a look at nix-util | 14:16:15 |
| dramforever | * but we definitely build nix with musl right? | 14:16:20 |
| matthewcroughan | it has worked a lot in the past yeah, though atm it's failing | 14:16:26 |
| matthewcroughan | I've never had an issue with it until this experiment | 14:16:40 |
| dramforever | well maybe close_range is new | 14:17:01 |
| matthewcroughan | looks like 2024 according to blame | 14:17:21 |
| dramforever | no look https://hydra.nixos.org/job/nix/master/buildStatic.nix-cli.x86_64-linux | 14:17:23 |
| matthewcroughan | ericsson was refactoring | 14:17:24 |
| dramforever | it's working | 14:17:35 |
| matthewcroughan | static and musl aren't the same are they? | 14:17:37 |
