build help #9

Closed waldenn closed 2 years ago

waldenn commented 2 years ago

Hi, could someone help me with the build-step. I'm trying to build Sparklis on an Ubuntu 20.04 system.

git clone https://github.com/sebferre/sparklis.git
cd sparklis
sudo apt-get install ocaml ocaml-findlib
make

Running the make command fails to install the Sparkliss package dependencies:

ocamlfind ocamlc -package csv,lwt,js_of_ocaml,js_of_ocaml-lwt,lwt_ppx,js_of_ocaml-ppx -c common.ml
ocamlfind: Package `csv' not found
make: *** [makefile:28: common.cmo] Error 2

Any idea how this can be fixed? Thanks!

Hi, first building from source is only necessary if you want to change the code. To reuse Sparklis in your website, please see the relevant section in the README.

For building OCaml projects, I strongly recommend to use opam to create a safe environment and install the required dependencies (ex: opam install csv).

Thank you for the feedback! I want to build from source and see how I can better integrate your project into my https://conze.pt project. I think it can help me to add a sub-system for handling 3rd-party SPARQL-endpoints. See this page: https://conze.pt/guide/concept_stores for some more background.

I installed opam and the required packages (see below), but ocamlfind still says: "Package ... not found". Do I need to configure ocamlfind in some way? Sorry, I'm not well versed in the OCaml world yet.

Make sure that you have set the OPAM-related environment variables. Scripts for setting them are available in ~/.opam/opam-init/ . You can also run the command eval $(opam env). When you run which ocamlc, it should return a path like ~/.opam/4.11.1/bin/ocamlc. Same for which ocamlfind.

Thank you Sébastien. Its building now.
