- About the OCAML core installation:
- Standard library: /cygdrive/c/opam/.opam/mingw-5.4/lib/ocaml
- Binaries: /cygdrive/c/opam/.opam/mingw-5.4/bin
- Manual pages: /usr/local/man
- Multi-threading type: posix
- The directory of site-specific packages will be
- site-lib: C:\opam\.opam\mingw-5.4\lib
- The configuration file is written to:
- findlib config file: C:\opam\.opam\mingw-5.4\lib/findlib.conf
- Software will be installed:
- Libraries: in <site-lib>/findlib
- Binaries: C:\opam\.opam\mingw-5.4\bin
- Manual pages: C:\opam\.opam\mingw-5.4\man
- topfind script: /cygdrive/c/opam/.opam/mingw-5.4/lib/ocaml
- Topfind ppxopt support: yes
- Toolbox: no
- Link custom runtime: no
- Need bytes compatibility: no
-
- Configuration has been written to Makefile.config
-
- You can now do 'make all', and optionally 'make opt', to build ocamlfind.
