再试下 xmake update -s dev

不行，另外我试了一下我之前写的 rule utils.ispc，也是构建失败

add_rules("mode.debug", "mode.release")

target("test")
    set_kind("binary")
    -- add_rules("utils.ispc", {header_extension = "_ispc.h"})
    -- set_values("ispc.flags", "--target=host")
    -- add_files("src/*.ispc")
    add_files("src/*.cpp")

    on_load(function (target)
        target:add("rules", "utils.ispc", {header_extension = "_ispc.h"})
        target:set("values", "ispc.flags", "--target=host")
        target:add("files", "src/*.ispc")
    end)

试下

    on_load(function (target)
        import("core.project.rule")
        local rule = rule.rule("utils.symbols.export_all")
        target:rule_add(rule)
        target:extraconf_set("rules", "utils.symbols.export_all", {export_classes = true})
    end)

ipsc 那个更新下 dev，然后参考上面使用

可以了，套用这个写法两个都构建成功
