Inconsistent assumptions

Learning
#1

I have the following inconsistent assumptions error. I carefully checked that there were no compiled files before I called make. Is there any way this error message could be improved to give more information? I see a previous request for this in October of last year, but I couldn’t find any answer.

thanks,
julia

For this particular error, you can use ocamlobjinfo to get more useful information. Running it on select.cma, select_commits.cmi, parmap.cma and parmap.cmi, and looking at the Parmap lines in the section “Interfaces imported”, you should see two different hashes (which is why the compiler is complaining).
If parmap.cmi and parmap.cma have different hashes for Parmap, then the parmap package is in an inconsistent state and you’ll likely need to reinstall it.
Otherwise, if select.cma and parmap.cma have different hashes, it likely means that another parmap.cmi was found in the load path when compiling select_commits.cmi. I don’t know any way to get the compiler to print the paths of loaded .cmis, but the directories used to look up files are the standard library (that you can get with ocamlc -where), the current working directory of the compilation command, and the ones passed with the -I flag on the command line. If there is an extra parmap.cmi somewhere in one of those directories, that would explain the error you get.

If you actually get the same hash for Parmap in all the mentioned files, then it’s possibly a bug in the compiler’s error reporting mechanism, and I would encourage you to submit a bug report.

I tried

opam uninstall parmap
opam install parmap

with no improvement. Also opam remove and then opam install. Is there a
more forceful way to reinstall it?

thanks,

Can you show which version of parmap you’re using, with opam show parmap for instance ?
If you’re using a pinned version, or at some point installed it with the --keep-build-dir flag, it’s possible that opam is installing files from an improperly built directory.

If you’re using the latest version from the official repo, I’m afraid I don’t really know what could have gone wrong; I would try opam remove parmap, then looking at the files installed in your opam switch to check that no parmap.cmi remains (with find ~/.opam/4.07.0 -name parmap.cmi, for instance). If there is one such file remaining, it’s probably the cause of the problem and you should delete it manually before re-installing parmap. If it’s not the case, I’m out of ideas. I’ve tried opam install parmap on a 4.07.0 switch on my side, and the parmap.cmi and parmap.cma I get are consistent. If you’ve got time to investigate, knowing if the issue remains with different versions of ocaml, parmap and opam could be useful.

Thanks for the help. opam clean removes parmap from the cache, and then
when I do an opam install, everything appears to be fine. But then when I
run my makefile, somehow it changes the hashcode of the cmi file.

I did have a previous non opam installation of parmap on the machine, but
I removed its cmi file.

I guess the problem is on my side somewhere. I’ll check my makefile in
more detail.

Thanks for your help.

OK, I see that the problem is on my side. Thanks for the help.
