Build failure on clang #2325

This is on aarch64 PC, let me know if you want me to try it on amd64.

$ export | egrep 'LANG|LC_CTYPE|TERM'

awesome, thanks for the report! got some interesting stuff in there.

/usr/include/pthread.h:1029:6: error: '__nonnull__' attribute parameter 3 is out of bounds
     __nonnull ((1, 2, 4));

this is not good...hrmm. so this seems to be a problem in your system headers? but that seems unlikely. what's declared on line 1029 of /usr/include/pthread.h? perhaps we're enabling some weird definition due to our compilation flags. i assume you've been able to build other things making use of pthreads =].

Not sure, I don't examine outputs of build scripts that closely unless they fail.

let's get lines 1028 and maybe even 1027 =] honestly if we could get the 10 or so around that. i'm looking for some kind of #ifdef or whatnot. honestly if you just want to attach the file, that might be best.

"parameter 4 is out of bounds"...but it is not? that looks perfectly legal. hrmmmm.

dankamongmen commented 3 years ago

yep, it's the pthread_cond_clockwait() defintion i pasted above, which is indeed controlled by __USE_GNU. the weirdness is that the __nonnull((1,2,4)) directive there is perfectly valid....hrmm.

alex3kov commented 3 years ago

Would trying gcc+binutils help?

dankamongmen commented 3 years ago

it might, but even if it does, i want to figure out what's going on here. clang builds just fine for me (and on any number of autobuilding setups, including some aarch ones). this is a surprising thing you have found!

dankamongmen commented 3 years ago

yeah, i'd love to know if gcc can handle this. is one of the arguments somehow being elided? even if those were null definitions, the comma would still break the parsing. strange!!

Wanted to watch the demo but that is make-only?

dankamongmen commented 3 years ago

no, notcurses-demo ought build just fine with ninja. nothing's "make-only" so far as i'm aware.

so it looks like things worked with gcc? or is that amd64 instead of arch?

are we still seeing the same problem compiling with clang on arm, as you initially were?

In documentation it says run make demo, so I assumed it's make-only. But now I see I can run ./notcurses-demo directly as well.

Things worked with gcc, arch seems to not be a factor.

Yes.

dankamongmen commented 3 years ago

thanks for the update. yeah you ought just be able to run ./notcurses-demo -p ../data.

dankamongmen commented 3 years ago

alright, since you have a way to build it, i'm deprioritizing this. i might try to get an ARM arch setup going and see if i can reproduce this. i don't understand the error that's being generated at all.

I used Generic AArch64 Installation root tarball of Arch ARM.

i have a raspberry pi 4 available now; that ought be able to run AArch64, and i can investigate this
