"Argument list too long" error when installing coq-unimath about platform

[MSoegtropIMC]

The issue appeared btw. with the new version of UniMath, which added a few files. With this the command line length for install exceeded 128k - which is a limit hard compiled into the Linux kernel (for whatever reason - neither macOS nor Windows have this).

[MSoegtropIMC]

OK. I will anyway see that I back port the fix to 8.16.

[MSoegtropIMC]

This is fixed in main with the 8.17 beta pick - it requires a patch to coq-makefile (to redirect the file list to a file). Which version of Coq did you use? One could back merge the fix to older versions of Coq.

See https://github.com/coq/platform/blob/main/opam/opam-repository/packages/coq-core/coq-core.8.17.0/files/0001-coq_makefile-put-file-to-install-list-in-file-instea.patch.

I am using Coq 8.16, the latest release offered by the installer.

What should I do to backmerge it? (or is it something you should do?) Or would using an older version of package pick work?

[MSoegtropIMC]

No - if you want coq-unimath 20230321 you need a patched coq-makefile.

If you want to use Coq 8.16 it might work to copy the above patch file to a subfolder "files" of https://github.com/coq/platform/tree/main/opam/opam-repository/packages/coq/coq.8.16.1 and register it in the opam file https://github.com/coq/platform/blob/main/opam/opam-repository/packages/coq/coq.8.16.1/opam like here

platform/opam/opam-repository/packages/coq-core/coq-core.8.17.0/opam

.

It might be that you have to adjust the patch file from 8.17 to 8.16 - nut sure if the coq-makefile template changed.

You do these changes in your local copy of Coq Platform. If you build again it should work.

[DCNick3]

Do I need to re-run the ./coq_platform_make.sh script or does it link back to my coq platform directory?

[MSoegtropIMC]

You should run the script, because you need to update the opam repos - the script does this automatically. The script doesn't redo things it already finished before.

If you know how to do this, you can also update the opam repos manually and reinstall coq with opam.

I've decided to go the path of least resistance and install coq-unimath.20220816. Thanks for the help 😅
