unison @2.51.2: ocamlopt: OCaml has been configured with -force-safe-string: -unsafe-string is not available.

[trebitzki (Timm Rebitzki)]

This is my first bug report.

Seems to bork on line 1039 of main.log:

:info:build Command failed:  cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_net_unison/unison/work/unison-2.51.2" && /usr/bin/make -w all UISTYLE=gtk2 THREADS=true 

Both paths are correct.

main.log for the unison installtion

It looks like the error is this:

827	:info:build ocamlopt -g -unsafe-string -I lwt -I ubase -I system -I fsmonitor -I fsmonitor/linux -I fsmonitor/windows -I system/generic -I lwt/generic -ccopt -mmacosx-version-min=10.15 -I /opt/local/lib/ocaml/site-lib/lablgtk2 -c /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_net_unison/unison/work/bcpierce00-unison-0176188/src/ubase/rx.mli

Thanks for your help Kencu! How can I resolve the issue? Should I reinstall ocaml? I have no idea how MacPorts works, I'm just a user...

[kencu (Ken)]

I'm afraid the version of unison we offer is not happy with the version of ocaml in use. I am not fluent in camel-speak, so until some kind soul comes along, the version here is not likely to build.

I see a version on the github releases page:

​https://github.com/bcpierce00/unison/releases/download/v2.51.3/unison-v2.51.3+ocaml-4.10.1+x86_64.macos-10.15.tar.gz

The gtk version is hardcoded to homebrew's parts:

% otool -L unison-gtk2
unison-gtk2:
	/System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa (compatibility version 1.0.0, current version 23.0.0)

	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1281.100.1)

but the plain version is not:

% otool -L unison
unison:
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1281.100.1)

% ./unison
Usage: unison [options]
    or unison root1 root2 [options]
    or unison profilename [options]

For a list of options, type "unison -help".
For a tutorial on basic usage, type "unison -doc tutorial".
For other documentation, type "unison -doc topics".

So the plain version works, if you download it from that (or one of the 20 other links with different versions).

Updating unison to 2.51.3 may help, which I've started to try to do, but I'm blocked by #62576.
