Jbuilder fails to build

jbuilder

#1

This error is already kind of confirmed by an OCaml developer in IRC, since he got the very same error number on Jbuilder some time ago, while nobody else was able to reproduce it back then.

The stdout and stderr files are both empty.

It seems like jbuilder is not installed.

What does ls $(opam config var bin)/jbuilder say ?

Maybe you should try to opam reinstall jbuilder.

I guess it’s too late now, but if there’s still something there (there shouldn’t) what happens if you try to run this binary manually ? and what are the permissions ?

Regarding the opam reinstall jbuilder failure it seems you should report this upstream.


#7

Hold on. It seems something really weird is going on in your switch. Here is seems it cannot run ocaml what happens with

opam config exec -- ocaml
ls -al $(opam config var bin)

Yep, its away.

Upstream means opam? jbuilder?


#10

jbuilder, but forget about this. Your problem is somewhere else, it seems opam is unable to execute anything that it installed. Can you run the binary ?

$(opam config var bin)/ocaml --version
echo $(opam config var bin)

I don’t understand what is going maybe you should simply rm -r .opam and start over.


#11

This is my output:

➜ ~ $(opam config var bin)/ocaml --version
The OCaml toplevel, version 4.05.0
➜ ~ echo $(opam config var bin)
/home/matthias/.opam/4.05.0+flambda/bin

The mentioned script:

build() {
cd “opam-full-$pkgver”

./configure --prefix=/usr
make -j1 lib-ext all
}

package() {
make -C “opam-full-$pkgver” DESTDIR="$pkgdir" install
}


#12

For some reason opam config exec can’t run what is in opam config var bin despite the fact that according to opam config exec -- env that the PATH is correctly setup. I’m sorry but I cannot help further.


#13

Any reason why you build it from source? Unsupported OS?

Have you tried purging .opam and start over?


#14

Yes, OCaml is supported here, opam not.

I rebuild all from scratch, opam init, opam update and then opam merlin. Still the same.


#15

:arrow_upper_right: upgrade jbuilder 1.0+beta12 to 1.0+beta13

Still the same issue.


#16

@AltGr indicates me that it may be due to https://caml.inria.fr/mantis/view.php?id=7640 could you try with a pre 4.05 compiler maybe.


#17

Would also report that I am having the same issue, here are my system specs

OS: MacOs 10.12.6
Ocaml Installation: homebrew
shell: fish shell (although this shouldn’t be a problem).

I also did a lot of the diagnostics and I am having the exact same results that @ShalokShalom is getting. Let me know if there is any way I can help!


#18

This has been confirmed to be a problem with an OPAM binary compiled with OCaml 4.05.0, due to changed semantics in the execvpe call.

Workaround: Run

 eval `opam config env`

in your shell before executing the opam command.

There is also a proposed PR in OCaml to regain the old execvpe behaviour in future releases, and @altgr is investigating backporting a fix into the opam 1.2 branch.


Having problems getting OPAM to install packages
#19

Can confirm that this works as a workaround


#20

Confirmed too.

Thanks a lot ^-^
