ocamlbuild

问题 I'm porting my application from OCaml 4.02.3 to 4.03.0. Say you have the following in lexer.ml : type t = T [@@deriving sexp] let () = sexp_of_t |> ignore; print_endline "hai" I'm trying to run it as following: ocamlbuild -use-ocamlfind -pkg ppx_sexp_conv -cflags '-w @a-4-31' lexer.byte -- But I'm getting the following error: Warning 31: files lexer.cmo and /Users/vladimir/.opam/4.03.0+flambda/lib/ocaml/compiler-libs/ocamlcommon.cma(Lexer) both define a module named Lexer File "_none_", line

问题 I have been working through the LLVM Kaleidoscope Tutorial for OCaml. On the third part of the tutorial, I have navigated to the example code in the folder OCaml-Kaleidoscope\Chapter3 I am encountering an issue when compiling with ocamlbuild toy.byte on cygwin. This is the code given in the tutorial to compile. The error I am getting is mkdir 'C:\Users\setup\Compiler\llvm\examples\OCaml-Kaleidoscope\Chapter3\_build' ''ocamlopt.opt unix.cmxa -I 'C:\OCaml\lib\ocamlbuild' 'C:\OCaml\lib

问题 I'm trying to compile an XML-RPC server written using the xmlrpc-light library in OCaml with ocamlbuild but I get: $ ocamlbuild server.native Finished, 0 targets (0 cached) in 00:00:00. + ocamlfind ocamlopt -linkpkg -package xmlrpc-light -package unix -package threads -package netsys -thread server.cmx -o server.native File "_none_", line 1, characters 0-1: Error: No implementations provided for the following modules: Netsys referenced from /usr/lib/ocaml/equeue/equeue.cmxa(Uq_engines)

问题 I'm trying to dump type information of all identifiers in an OCaml project, basically it's the same as traversing the typed abstract syntax tree(https://github.com/ocaml/ocaml/blob/trunk/typing/typedtree.mli). Since I'm new to OCaml compiler's codebase, I'm not sure whether the Compiler has provided apis so we could easily write a plugin to do the job or we have to hack the compiler code? Also how does this interact with OCamlbuild? Thanks for any hints or advices. 回答1: Assuming you have

问题 I recently decided to organize the files in my project directory. I moved the parsers I had for a few different file types into their own directory and also decided to use ocamlbuild (the as the project was getting more complicated and the simple shell script was not sufficient any longer). I was able to successfully include external projects by modifying myocamlbuild with some basic rules (calling ocaml_lib , I'll use ocamlfind some other time), but I am stuck on how to include the folder as

问题 I have an existing project in OCaml and one _oasis file. I don't know where to enable the profiling flag for ocamlbuild . I looked up Oasis manual and the code, and found there was a variable profile available in setup.data. I assume this was what Oasis auto generated. Where and what should I include in _oasis to set profile to true ? 回答1: You can activate the ocamlbuild_more_args feature. On top of your _oasis file: AlphaFeatures: ocamlbuild_more_args Then, in your Package:

问题 I have hello.ml that has a length function: let rec length l = match l with [] -> 0 | h::t -> 1 + length t ;; call.ml that uses the function: #use "hello.ml" ;; print_int (length [1;2;4;5;6;7]) ;; In interpreter mode (ocaml), I can use ocaml call.ml to get the results, but when I tried to compile it with ocamlc or ocamlbuild, I got compilation error. File "call.ml", line 1, characters 0-1: Error: Syntax error Then, how to modify the caller, callee, and build command to compile the code into

问题 I have an OCaml project that is currently built using OCamlMake. I am not happy with the current build system since it leaves all build artefacts in the same directory as source files, plus it also requires to manually specify order of dependencies between modules. I would like to switch to a build system that does not suffer from these issues. I decided to give Oasis a try but have run into issues. The problems arise from the fact that the project is built in a very specific way. It supports

问题 I am a new OCaml user. I have asked a question to learn how to set up a basic OCaml project, but I still have issues. Jump to the end for a TL;DR For instance, I am trying to learn Irmin. On the home page of Irmin I see I have to do opam install irmin git cohttp Doing so, I end up with Irmin version 0.8.3. Unfortunately, I cannot follow their examples, because apparently Irmin is at version 0.9.4, and it looks like the API has changed. So, I would like to start a clean project having as

问题 Can I specify the build location and file name with the ocamlbuild tool? I would like to be able to say (in pseudocode): ocamlbuild myapp.ml -b native -o bin/myapp 回答1: There is no such option, but ocamlbuild is extensible and allows you to add your own options with Options.add . Of course, you will also need to add some implementation. Basically, hijacking the rule for native and extending it with installation procedure may work. To extend ocamlbuild you should write a plugin (other option
