Some failures due to 404 rev deps. The others are due to stack limits. See dbuenzli/uunf#16 We looked with @kit-ty-kate but it seems a bit unclear on what exactly has to be done. A work around is to compile with ulimit -s unlimited.

[mseri]

Should we add a post-install failure message on ppc64 and aarch64 to say that? Something like "In case your build fails with "ocamlopt.opt got signal and exited", please retry the compilation with "ulimit -s unlimited".

[dbuenzli]

Oh I think it's a good idea. @kit-ty-kate suggested to

build: [
  [<normal-build>] {arch != "ppc64"}
  ["sh" "-c" "ulimit -s unlimited && <normal-build>"] {arch = "ppc64"}
]

but I'm rather against these things since they make problem go under the radar. But having a message seems good.

[mseri]

Yeah, that is a nice hassle free solution, but honestly I prefer for it to fail informatively rather than do magic that I would prefer to have control over

[dbuenzli]

Ok I'll look into that later this afternoon. If on the top of your head you have a package in mind where I can copycat the syntax from, welcome. Otherwise I'll dig into the manual.

Sure:

The post messages where added in uunf and uucp.

Thanks a lot
