Yocto include/config.h:致命错误：configs/.h:没有这样的文件或目录

我正在使用Poky发行版2.0.1构建u-boot v2015.07（移植任务）。但是，我遇到了以下错误

| In file included from ./include/common.h:18:0:
| include/config.h:5:22: fatal error: configs/.h: No such file or directory
| In file included from ./include/common.h:18:0:

| compilation terminated.

| make[1]: *** [include/autoconf.mk] Error 1

| make: *** No rule to make target `include/config/auto.conf', needed by `include/config/uboot.release'.  Stop.
| WARNING: exit code 1 from a shell command.
| ERROR: oe_runmake failed

config.h文件由脚本/Makefile.autoconf生成。我已经添加了配置头文件include/configs/iwg20m_q7.h，并在board/renesas/iwg20m_q7/Kconfig中声明了SYS_config_名称，如下所示：

if TARGET_IWG20M

config SYS_BOARD
       default "iwg20m_q7"

config SYS_VENDOR
       default "renesas"

config SYS_CONFIG_NAME
       default "iwg20m_q7"

endif

但是，我不知道$（CONFIG_SYS_CONFIG_NAME）（在scripts/Makefile.autoconf中）如何获得SYS_CONFIG_NAME的值（在board/renesas/iwg20m_q7/Kconfig中）。因此，一旦生成config.h文件（缺少正确的目录和SYS_config_名称iwg20m_q7），就会导致失败

重建后，我看到.config文件也已正确更新，甚至在arch/arm/Kconfig文件中添加了“source”board/renesas/iwg20m_q7/Kconfig”行

---

然而，这个问题仍然没有得到解决。有人能帮我解决这个问题吗？谢谢。

大家好，我通过在ARCH/arm/Kconfig文件中添加

choice
提示符“Target select”
可选
+默认的ARCH_IWG20M

解决了这个问题，还添加了

+config Target_IWG20M
+bool“支持IWG20M\u q7”
+在arch/arm/Kconfig文件中选择CPU\u V7
+
