Error building ocaml-base-compiler.5.2.0 on x86_64 windows

Logan-010 commented 1 week ago

I am attempting to install ocaml via opam 2.2, because DkML OCaml does not use the latest version (& is missing thread support), However, after everything going OK during an opam init the build process fails with a few bizarre error messages while attempting to build ocaml-base-compiler.

⬇ retrieved ocaml-base-compiler.5.2.0  (https://opam.ocaml.org/cache)
[ERROR] The compilation of ocaml-base-compiler.5.2.0 failed at "make -j31".

here is the piece of code the build process is failing on: runtime/prims.c

const char * const caml_names_of_builtin_cprim[] = {
  "caml_abs_float
",
  "caml_acos_float
",
  "caml_acosh_float
",
  "caml_add_float
",
  "caml_alloc_dummy
",
  "caml_alloc_dummy_float
",
  "caml_alloc_dummy_function
",
  "caml_alloc_dummy_infix
",
  "caml_alloc_stack
",

(Note this is not the full file)

fixed it, some odd issue with the c compiler i had in my path.

Instead of 'use tools in path: _" in the opam setup, i selected 'install for me (recommended)', which was recommended for a reason apparently.
