Hello the list,

I have a strange behavior from my opam setup recently, I’ll reproduce the steps that trigger this singularity :

1.a. it does happen at least when trying to compile examples of a jane-street new package, the bonsai incremental web framework.
1.b. it shows only when trying the production profile with dune : « dune build --profile=release ./hello_world.bc.js »

2. here we go with the command sequence :

philou@air:~/mysrc/tmp/time$ dune build --profile=release ./hello_world.bc.js

(the build start, and fail before completion with the following err msg :)

File "_none_", line 1:
Error: Error on dynamically loaded library: /Users/philou/.opam/4.09.0/lib/stublibs/dllcore_kernel_stubs.so: dlopen(/Users/philou/.opam/4.09.0/lib/stublibs/dllcore_kernel_stubs.so, 10): Symbol not found: _caml_stat_heap_size
  Referenced from: /Users/philou/.opam/4.02.3/lib/stublibs/dllcore_kernel_stubs.so
  Expected in: flat namespace
 in /Users/philou/.opam/4.02.3/lib/stublibs/dllcore_kernel_stubs.so

(notice the opam switch complete mixing of switch 4.09.0 w 4.02.3)
(jane-street support then asked me to try the following: open a bash without profile or run-command execution, for compiling bonsai examples later)

philou@air:~/mysrc/tmp/time$ bash --noprofile --norc
bash-3.2$ pwd
/Users/philou/mysrc/tmp/time

(let’s try it : )

bash-3.2$ dune build --profile=release ./hello_world.bc.js

(and it builds to completion without a glitch :)

bash-3.2$ ls -altr _build/default/

drwxr-xr-x  4 philou  staff       408 28 nov 13:56 .

bash-3.2$ ln -s _build/default/hello_world.bc.js hello_world.bc.js
bash-3.2$ open index.html

(works as expected!)


Q: what happened to my opam setup, and is this a dune or opam « bug » ?

TIA.
Regards

Your environmental variables for your regular shell are probably messed up. This might also mean that packages you installed after it got messed up are also corrupted in subtle ways.

One way would be to trash out your `.opam` directory and remove any lines for OPAM initialisation (e.g. in `.bash_profile`) and starting again. Make sure there isn't anything you are going to miss if you delete `.opam` and be prepared to wait for the building of a new switch and the packages you need.
