Hello,I'm building a pair of companion oasis build spec and opam package setup for a C library. libdai I figured out how to get swig and oasis to build most things I need, but I'm having trouble getting oasis to not generate _stubs targets that aren't found. There is a static C/++ libdai.a file that is the product of the project I'm trying to wrap. I can't convince oasis to use that instead. Here's my _oasis target:Library "dai"Path: ./Install: falseModules: Swig, DaiCompiledObject: bestCSources: dai_wrap.cxx.cCCOpt: -g -xc++ "-I../../include"With a fresh clone of libdai, I get dai_wrap.cxx.c by doing the following in ./swig after building libdai:$(SWIG) -ocaml -c++ dai.imv dai_wrap.cxx dai_wrap.cxx.csed -i -e 's/caml_array_length/caml_array_len/g' dai_wrap.cxx.c I got my swig and dai ml files by doing the following:swig2.0 -ocaml -co dai.mlswig2.0 -ocaml -co swig.mlswig2.0 -ocaml -co swig.mliI build by doing the following:ocaml setup.ml -configureocaml setup.ml -build
I get the following error:Solver failed:Ocamlbuild knows of no rules that apply to a target named ./libdai_stubs.a. This can happen if you ask Ocamlbuild to build a target with the wrong extension (e.g. .opt instead of .native) or if the source files live in directories that have not been specified as include directories.Compilation unsuccessful after building 8 targets (8 cached) in 00:00:00.E: Failure("Command ''/usr/bin/ocamlbuild' ./libdai_stubs.a ./dlldai_stubs.so ./dai.cma ./dai.cmxa ./dai.a ./dai.cmxs -j 5 -tag debug' terminated with error code 6")I want to make sure that the actual target shared library that was produced by the libdai build file itself is linked against. But oasis is assuming I have a _stubs target. I read in the documentation here that: "The usual idiom is to append_stubs
to the name."https://ocaml.org/learn/tutorials/setting_up_with_ oasis.html#Interfacing-with-C- code
And I think that that is the source of the error, but it isn't well explained. The ultimate things I originally wanted was to be able to use libdai with both the utop or the bytecode interpreter and with fully compiled targets. I was going to make libdai a library and then publicize it.If anybody needs to replicate my issue, I have a docker container with this already.
