| Description | Basically, it is up to the user how to call the C compiler for compiling stublibs. However, in many build systems I see that users do it the wrong way (e.g. hardcode the compiler "gcc", or forget to pass switches like -fPIC which are sometimes required). My wish is that the section "Interfacing C with OCaml" includes examples how to do it right - which is absolutely simple, because you just need to use ocamlc as driver even for C sources.
There could e.g. be a new section before "Statically linking C code with OCaml code" about "Compiling C code". Contents:
- How to use ocamlc as driver for C sources: Sample command
- Mention that the stdlib is automatically in the include path
- Mention that the switches are ok for dynamically loadable code
- The created .o files can be args of ocamlmklib
- use -I, -ccopt, -cclib to pass args
- Mention that ocamlc -config can be used to extract the compiler path and switches if lower-level calls are needed |
