编译牛仔项目忽略错误

Question

我对 ERLC_OPTS 进行了修改，或者我是这么认为的。不得不清理我的 erlang.mk 但没有保存它。

在哪里添加警告 ok 标志？

我尝试将 -W0 添加到此：

Write(["ERLANG_ARCH = ", rebar_utils:wordsize(), "\nexport ERLANG_ARCH\n"]),
        fun() ->
                Write("ERLC_OPTS = +debug_info -W0\nexport ERLC_OPTS\n"),
                case lists:keyfind(erl_opts, 1, Conf) of
                        false -> ok;
                        {_, ErlOpts} ->

但我仍然遇到该错误。

您可以尝试通过设置 ERLC_OPTS 来过滤掉 Erlang.mk 用于编译的默认选项，如下所示： ERLC_OPTS := $(filter-out -Werror,$(ERLC_OPTS)) 根据 Erlang.mk user guide
