I just installing uri
under 3.12.1 without any issues.
3.12.1 is under your system ocaml compiler, right? and you probably installed ocaml via aptitude? In which case you need to also install ocaml-compiler-libs
. There are a number of other optional packages for OCaml that are usually needed and may run into in the future --camlp4-extra
is another that I see missed and oft needed. A maximal list is here.
I would also upgrade OPAM
, since there were some changes to the uri
package only two days ago. opam update; opam upgrade
. This will require some re-compilation, and make sure you switched to the correct compiler.
