cmxs files not installed

[nilsbecker]

Expected Behavior

the standard build of the library owlbarn/eigen should include eigen.cmxs

Actual Behavior

only eigen.cmxa is present

Reproduction

opam install eigen, then check the build directory

Specifications

dune 2.7.1
ocaml 4.10
macos catalina

Additional information

see owlbarn/eigen#27
for more information.

Sorry, but I cannot reproduce the issue. The .cmxs is built fine in my machine. Do you have a build log that you may be able to share? (Look in _build/log after doing dune build).

[nilsbecker]

hi, i might have given incomplete info. i did not build eigen myself, i installed it via opam -- the list of installed files is the one i gave in owlbarn/eigen#27 . there, the cmxs seems to be missing.

the dune-package file in $OPAMROOT/<switch>/lib/eigen/dune-package is this:

in fact, in $OPAMROOT/<switch>/.opam-switch/build/eigen/_build/install/default/eigen/ i have these files:

which does include eigen.cmxs ?!

Given that you have eigen.cmxs in your installation and there isn't anything specific in the build log, it looks like you just had some transient issue in the past, and there is no actual problem. Can you confirm that you can use the .cmxs file normally?

[nilsbecker]

no, sorry there is again a miscommunication -- the eigen.cmxs file exists in the _build directory hidden in the .opam-switch private build tree. however, it is still not installed (i.e. not in the lib/ directory of the public opam switch directory) and it's not available to users of the library. (check the directories i mentioned above)

so the issue persists. what i find confusing is that the file is indeed built but not installed

[nojb]

Can you post the list of files that you have in the "eigen" lib directory of the OPAM switch directory $OPAMROOT/<switch>/lib/eigen/ ?

[nojb]

For info, in owlbarn/eigen#27 the list of files is missing eigen.cmxs but contains eigen.cmxs.startup.o. This file is generated by the compiler during the linking phase of eigen.cmxs and normally it is deleted afterwards, so it is rather bizzare that it found its way to the installation directory.

[nilsbecker]

aha this might be a lead.

yes, the list of files in the installation directory is the one i posted in owlbarn/eigen#27.
i now did a opam reinstall eigen with that switch activated.

i got one warning message:

[NOTE] While removing eigen.0.3.0: not removing non-empty directories:
         - lib/eigen

so i deinstalled eigen with opam, which left the .startup.o file in there.
i then manually removed that directory and did opam install eigen. voila, the eigen.cmxs is there.
there might have been a failed installation procedure at some point before which created the persistent startup.o. file?

anyway, now the file is installed!
my original intent was to load eigen from the native toplevel using omod.
when i do

#use "omod.nattop";;
Omod.load "Eigen";;

this now finds eigen.cmxs. however, i get a linking error:

Error while loading /Users/nbecker/.opam/410nattop/lib/eigen/eigen.cmxs: error loading shared library: Dynlink.Error (Dynlink.Cannot_open_dll "Failure(\"dlopen(/Users/nbecker/.opam/410nattop/lib/eigen/eigen.cmxs, 10): Symbol not found: _c_eigen_dsmat_c_cols\\n  Referenced from: /Users/nbecker/.opam/410nattop/lib/eigen/eigen.cmxs\\n  Expected in: flat namespace\\n in /Users/nbecker/.opam/410nattop/lib/eigen/eigen.cmxs\")").

but that is probably not a dune problem. i might report back at owlbarn/eigen ...

[nojb]

Great, thanks for letting us know. Indeed, for your follow-up problem, it looks like something you should take up with the maintainers of eigen. Thanks!
