Having some trouble using [Core] library in windows.

For 5.x.x I'm getting the following error with open Core:

File "bin/dune", line 3, characters 7-11:
3 |  (name main)
           ^^^^
** Cannot resolve symbols for C:\opamroot\opam-01f65a\5.3.0\lib\base_bigstring\libbase_bigstring_stubs.a(base_bigstring_stubs.o):
 memmem
File "caml_startup", line 1:
Error: Error during linking (exit code 2)

For 4.14.2 I'm getting the following error when trying to opam install core:

# File "core/src/dune", line 11, characters 10-25:
# 11 |  (c_names bigstring_stubs md5_stubs array_stubs gc_stubs time_ns_stubs)

  • Did you use opam to install OCaml? Commented Apr 21 at 16:40
  • This issue has already been reported and I’m using a patched version when I’m compiling the code for windows. We just wait for the dev to update the code. Commented Apr 22 at 6:09
  • @Chimrod how did you apply the patch? Did you just clone core, apply the diff, and use the core library locally? Commented May 17 at 2:31
