Build issue with jsont.0.1.0 package

[mbarbin]

I'm not sure what's specific in my setup. I'd appreciate some help if you can think of something!

First attempt:

$ opam install jsont bytesrw
The following actions will be performed:
=== install 2 packages
  ∗ bytesrw 0.1.0
  ∗ jsont   0.1.0

The log has:

ocamlfind: Package `b0.std' not found
Command exited with code 2.

I thought I could try to install b0 and tried again (probably a bad idea in retrospect, as I don't suppose this should be required). At any rate, with b0.0.0.5 installed, this time the error was:

+ ocamlfind ocamlc -c -g -bin-annot -safe-string -package 'cmdliner bytesrw b0.std' -I test -I src -I src/bytesrw -o test/jsont_tool.cmo test/jsont_tool.ml

Ah crap I forgot to remove the dependency on b0.std in the jsont tool.

(You can pin b0 meanwhile).

(You can pin b0 meanwhile).

That worked, thanks!

I did so at 245bd6f066c5ea0632177a162fc608d9f6a0f24e (2024-11-10)
