| Summary | 0005653: unnecessary rebuild for some rules | |||||||||||
| Description | This rule will rebuld cmxs everytime, as along as I don't have .so rule "ocaml: mldylib & cmx* & o* -> cmxs & so" ~tags:["ocaml"; "native"; "shared"; "library"] ~prods:["%.cmxs"; x_dll] ~dep:"%.mldylib" (Ocaml_compiler.native_shared_library_link_mldylib "%.mldylib" "%.cmxs");; This also applies this rule, when I only need build .cmx, it will rebuild .cmo everytime since I need it to build cmi. rule "ocaml: ml -> cmo & cmi" ~tags:["ocaml"] ~prods:["%.cmo"; "%.cmi"] ~deps:["%.ml"; "%.ml.depends"] (Ocaml_compiler.byte_compile_ocaml_implem "%.ml" "%.cmo");; Since I switched to ocamlbuild, I found the performance degraded a lot. It works, but it is really *slow*. It is possible to make the rules more customizable without introducing a big database with a lot of reduandance? | |||||||||||

Just remove x_dll works, how do I tell ocamlbuild which rule is used first? rule "ocaml: mldylib & cmx* & o* -> cmxs" ~tags:["ocaml"; "native"; "shared"; "library"] ~prods:["%.cmxs"] ~dep:"%.mldylib" (Ocaml_compiler.native_shared_library_link_mldylib "%.mldylib" "%.cmxs");; Many thanks |

oasis 0.3 switches to always produce .cmxs and I see that rebuilding .cmxs is done everytime. This is quite annoying. tip: set "./configure --override is_native false" to avoid that |

Use ~insert optional argument for rule to insert at given place the rule. In your case: rule "ocaml: mldylib & cmx* & o* -> cmxs" ~insert:`top ~tags:["ocaml"; "native"; "shared"; "library"] ~prods:["%.cmxs"] ~dep:"%.mldylib" (Ocaml_compiler.native_shared_library_link_mldylib "%.mldylib" "%.cmxs");; should be enough to get your desired effect. Another way of doing that would be to use Before_rules dispatch entry point. Closing this PR, with a note that documentation should be updated reflecting this information. |
