real-connect | 《前線科技人員》真・WeConnect ️ | Software As A Service library

You are missing commas before the parts that are to be evaluated:

1. MYSQLI_OPT_SSL_VERIFY_SERVER_CERT (true) used when you want to verify server certificate against well known authorities to ensure that this is connection to trusted host. Do not use it if you have self-signed certificate on server.

2. MYSQLI_CLIENT_SSL must be always used when you need to encrypt connection.

3. When you have on mysql-server certificate provided by authorities and want encryption + MITM-attack protection use both MYSQLI_OPT_SSL_VERIFY_SERVER_CERT and MYSQLI_CLIENT_SSL.

First off, you're not getting an error for connect because there's already a connect function in the standard library. I strongly suggest renaming your function because mysql_real_connect likely uses the standard connect internally and this would cause infinite recursion if you override it like this.

Quoting from the OCaml manual:

If you are using the native-code compiler ocamlopt, the -custom flag is not needed, as the final linking phase of ocamlopt always builds a standalone executable. To build a mixed OCaml/C executable, execute the ocamlopt command with:

• the names of the desired OCaml native object files (.cmx and .cmxa files);
• the names of the C object files and libraries (.o, .a, .so or .dll files) that implement the required primitives.

And also:

The ocamlopt command has a command-line interface very close to that of ocamlc. It accepts the same types of arguments, and processes them sequentially, after all options have been processed:

[...]

• Arguments ending in .cmx are taken to be compiled object code. These files are linked together, along with the object files obtained by compiling .ml arguments (if any), and the OCaml standard library, to produce a native-code executable program. [...]

• Arguments ending in .c are passed to the C compiler, which generates a .o/.obj object file. This object file is linked with the program.

And later:

-cclib -llibname
Pass the -llibname option to the linker . This causes the given C library to be linked with the program.

DISCLAIMER: I haven't actually tested the following steps. This is just what I think would make sense from reading the documentation.

From this I assume a correct compilation command would look like
