Openwrt SDK：生成文件权限被拒绝

Question

我正在使用 OpenWRT SDK 编译一个用户包。源文件位于 OpenWrt-SDK-ar71xx-generic_gcc-5.2.0_musl-1.1.11.Linux-i686/package/adapter/src。

在/adapter/src目录下，我还有Makefile:

adapter: adapter.o
    $(CC) $(LDFLAGS) adapter.o -o adapter
adapter.o: adapter.c
    $(CC) $(CFLAGS) -c adapter.c
clean:
    rm *.o adapter

运行 /adapter/src 目录中的本地生成工作正常。

然后我将以下 Makefile 添加到 /adapter 目录：

include $(TOPDIR)/rules.mk
PKG_NAME:=adapter
PKG_RELEASE=1

PKG_BUILD_DIR:=$(BUILD_DIR)/$(PKG_NAME)

include $(INCLUDE_DIR)/package.mk

define Package/adapter
    SECTION:=utils
    CATEGORY:=Utilities
    TITLE:=adapter --prints a dummy message
endef

define Build/Prepare
    mkdir -p $(PKG_BUILD_DIR)
    $(cp) ./src/* $(PKG_BUILD_DIR)
endef

define Build/Compile
    $(MAKE) -C $(PKG_BUILD_DIR) $(TARGET_CONFIGURE_OPTS)
endef

define Package/adapter/install
    $(INSTALL_DIR) $(1)/bin
    $(INSTALL_BIN) $(PKG_BUILD_DIR)/adapter $(1)/bin
endef

$(eval $(call BuildPackage,adapter))

当我在顶层目录中运行 make 时，出现以下错误：

zy@zy-OptiPlex-745:~/openwrt/OpenWrt-SDK-ar71xx-generic_gcc-5.2.0_musl-1.1.11.Linux-i686$ make V=99

运行 make as root 给出同样的错误。有人可以建议吗？谢谢！

根据你的信息，我认为这个错误可能是/adapter目录下的Makefile引起的。

define Build/Prepare
    mkdir -p $(PKG_BUILD_DIR)
    $(cp) ./src/* $(PKG_BUILD_DIR)
endef

应该这样修改：

define Build/Prepare
    mkdir -p $(PKG_BUILD_DIR)
    $(CP) ./src/* $(PKG_BUILD_DIR)
endef

$(CP)是一个变量，定义在rules.mk CP:=cp -fpR 所以你可以用它来复制一些东西。
