It is perhaps not “ok”, but both are AUR packages.
Those are at the end of the day your responsibility - or you can notify the packager.

If somebody else can reproduce this issue would be helpful, in case it’s a bug in my system.

4

My system is on stable branch.
(did this in a VM - Xfce4, if that is of interest)
I did not have any of this installed before - it was just a test.

I just did:
sudo pacman -Syu
to make sure the system is up to date

then:
yay -S ocaml4-ocamlbuild
(no issues)

then:
yay -S ocaml4-findlib

that last step fails, but the install error is a different one - but it was built without issue
it fails because the file
/usr/lib/ocaml/ocamlbuild/META
is already present from installing ocaml4-ocamlbuild

It is not identical to the one going to be installed, but looks functionally identical.
(You are the expert on judging whether that is truly the case - compare them.
I have zero clue about ocaml …)

so, I moved it out of the way:
sudo mv /usr/lib/ocaml/ocamlbuild/META /home/me

and then
yay -S ocaml4-findlib
finishes without error.

Click the line or the arrow to expand.

here are the two files for comparison: 
cat META_1
# Specification for the "ocamlbuild" library
requires = "unix"
version = "0.14.2"
description = "ocamlbuild support library"
archive(byte) = "ocamlbuildlib.cma"
archive(native) = "ocamlbuildlib.cmxa"

cat META_2
# Specification for the "ocamlbuild" library
requires = "unix"
version = "[distributed with Ocaml]"
description = "ocamlbuild support library"
directory= "^ocamlbuild"
archive(byte) = "ocamlbuildlib.cma"
archive(native) = "ocamlbuildlib.cmxa"

If it does not need to be version 4, the more recent versions of ocaml are in the repo, as you probably know.

HTH

5

You are not supposed to manually delete any file because now is missing from the other package. If there’s a new version of ocaml it wasn’t upgraded automatically for me, maybe because I’m specifying the version?

6

I temporarily removed that one file to allow the install procedure of the other to succeed.
To be more precise and as I said:
I did not remove it, I simply moved it so that the other could take it’s place.
This can be reversed since both files are still there.
I have included both versions in my previous post for comparison - they seem to be functionally the same.

Of course it is not lege artis or how things should be done - but I was interested in making it work.

The packager is the same for both of these - ask him how to deal with it, ask him to adapt the PKGBUILD.

I’m of the opinion that either one of these /usr/lib/ocaml/ocamlbuild/META files will work.
But I don’t know.
That’s not my expertise.

re your actual request:
I did try to reproduce your issue - and couldn’t.
Instead I discovered this one …

Best of luck!

ps:

You had installed version 4 from AUR.
This will never be replaced by version 5 which is in the repos.

If you don’t need version 4 specifically, just remove the AUR versions and install from the normal repos.

Arch Linux - Package Search

You’d obviously save the time to have to compile the things and it will, presumably, just work.

7

I’m pretty sure it was installed as a dependency for another package, and the other package doesn’t acknowledge it and doesn’t switch automatically to ocaml5.

8

Only you can know that.
If you don’t care about the version - or if you don’t even know why it is even there … just remove.
Or try to remove and discover that way what requires it.

That is the problem with AUR packages - you need to have an eye on those yourself.
They may become obsolete or need to be recompiled after updates to the base system.

They may have been the cutting edge at one time in the past, the latest and greatest …
but eventually the repo will catch up and make them first unnecessary and even incompatible.

Custom packages is not built as a dependency for repo packages.

So if it has been pulled as a dependency it is a custom build as well.

Although any custom script on AUR must meet the guidelines - there is nothing to prevent the same file being a part of multiple depending packages.

10

Have you tried this?
Hopefully it won’t cause too much “Trouble with Tribbles*”.

Sorry, couldn’t resist the reference, don’t think I’m the first one either.

not with what you told it to do (via the command you gave …)

remove all the stuff:
pacman -Rns ocmlXYZ...xyz

it will (try to) recursively remove your AUR packages and everything depending on them with it.

you will see what is about to happen if you say “yes”.
you can cancel if you are unsure …

But:

you seem to have managed to remove it anyway

good

and now?

any issues?

…

the package that required ocaml may still be there after what you did

Is it still working?
Do you know what/which it is?

RISC OS is indeed very, very different to Unix/Linux.

Try to detach from what you might have learned how an OS behaves from Risc OS.
Unix is just different.
not better, not worse, just different

13

You can just remove ocaml4 , that will remove all except for ocaml4-lablgtk2 (maybe will be fixed in the future) since all the others depends on ocaml4

mldonkey-git also requires them.

16

As I demonstrated, the compilation works and ocaml gets installed with one minor flaw which is easily circumvented.
Or adapt one of the the PKGBUILD’s so that that doesn’t happen …
@Lolix might know how - it seems he is the maintainer of the AUR packages himself

But all that is not even needed:

have a look at the the first comment on the AUR page for mldonkey.
… a link to a prebuilt version which you can download and install using
sudo pacman -U the_downloaded_file

No need to have ocaml in this case - it is just needed during build time, not for using the resulting mldonkey

17

That command skips all dependency checks.

 -d, --nodeps
           Skips dependency version checks. Package names are still checked. Normally, pacman will always check a package’s dependency fields to ensure that all dependencies are installed and there are no package conflicts in the system. Specify this option twice to skip
           all dependency checks.
18

It is not checked because you are using dd options

Looking at AUR (en) - ocaml4 you can what need it as depends

Yes, they are required at build time

19

That demonstrates that copy & paste commands is not always a good idea.

Yeah, it certainly helps if you understand what you’re copy/pasting before running it.

I’m going back quite a few years, but it used to be fairly common to find posts telling people to run sudo rm -r / as a “joke” all over the internet. It was the linux version of “you’re too stupid to own a computer”.

They eventually changed rm to check if it was being run on / and give a warning, but it doesn’t apply to /*, etc.
