[Caml-list] How to build a library with c++ stubs

[Caml-list] How to build a library with c++ stubs

[Leonardo Laguna Ruiz]

Hi,

I’m working on a library which wraps functions and clases written in C++. I’m trying to setup a build system based in oasis but I haven’t found any example on how to do it.

So far I have been able of compiling my test programs using cmake and ocamlbuild. I use cmake to generate a static library out of my C++ file. Then I call ocamlbuild (from cmake) to generate a object file from my main file (main.native.o). Finally I link everything using cmake.

I have tried to link the my test program with ocambuild by passing all the necessary flags (use stdlib=libc++ and link CoreFoundation and IOKit in OS X) but I haven’t succeeded using ocamlbuild (or oasis).

Does anyone has an example on how to build a library that uses C++ code?

Thanks,

Leonardo

Hi Leonardo,

In BAP project we're building C++ bindings with oasis+ocamlbuild.  Look at
`cxx_rule` in `myocamlbuild.ml.in` file,
definitions like `cxx` and `cxx_flags` in `setup.ml.in` and, of course,
`_oasis`

Feel free to ask any questions,

Regards,
Ivan

Thank you everyone for your answers.

I was checking the examples that Ivan G. and Martin D. sent.  But it 
took me some time to find out how everything worked, specially because I 
haven't made any ocambuild plugin and is my first time using oasis.

I ended up using the renaming of files as Ygrek suggested in the link. 
If the issue that Peter Z. is fixed I guess that I just need to rename 
the files back and remove the flags.

@Shane F. I used the method you describe in the blog post when I had my 
cmake based build system.

Soon I'll be releasing my library once I test that works correctly in 
all the platform I want to support.

Leonardo
