オアシスにOCAMLOPTFLAGSを追加するには？

Question

私は_oasisファイルにいくつかのフラグ（S、インライン20、nodynlink）を追加したいと思いますが、私はコンパイルエラーを取得：

AlphaFeatures: ocamlbuild_more_args 
XOCamlbuildExtraArgs: "-cflags '-S -inline 20'" 

私はどのようにこれらを追加することができ疑問に思って。

かなり長いエラー：

Answer 1

-cflagsオプションは、オプションのカンマ区切りのリストを取り、ocamlcコンパイラに渡します。したがって、ocamlbuild' src/main.native -cflags -S -inline 20では-Sオプションのみがocamlcに渡され、-inlineと20はocamlbuildによって取得されます。だから、ocamlcに複数のオプションを渡すための正しい方法は次のとおりです。

ocamlbuild -cflags -S,-inline,20 x.byte 

彼らはocamloptのオプションですようocamlcは、-cflagsまたは-inlineオプションを認識しないので、これはまた、しかし、失敗します。 OCamlには2つのコンパイラがあり、1つはocamlcと呼ばれ、バイトコードが生成され、もう1つはネイティブコードを生成するocamloptです。彼らはいくつかの共通の選択肢を持っていますが、いくつかは共有されていません。たとえば、バイトコードコンパイラはアセンブリを生成できません。あなたは_oasisでNativeOptフィールドを使用するか（後者はflambdaを制御するのに便利です）_tagsファイルにパラメトリックタグを使用するかocamloptにオプションを渡すこと

。認識されたタグの実際のセットについてはocamlbuild -documentationを見てください。
