Kconfig:5: warning: BSP_ROOT has 'option env="BSP_DIR"', but the environment variable BSP_DIR is not set
Kconfig:5: warning: Kconfiglib expands environment variables in strings directly, meaning you do not need 'option env=...' "bounce" symbols. For compatibili

warning: the menuconfig symbol RT_USING_THREAD_DETACH_HOOK (defined at ../../rt-thread/kernel/Kconfig:168) has no prompt
menuconfig: Kconfig:18: 'D:\tools\env-windows\packages/lwar/Kconfig' not found (in 'source "$PKGS_DIR/lwar/Kconfig"'). Check that environment variables are
set correctly (e.g. $srctree, which is unset or blank). Also note that unset environment variables expand to the empty string.

我的Kconfig是这样写的：

mainmenu "RT-Thread Project Configuration"

config BSP_DIR
    string
    option env="BSP_ROOT"
    default "."

config RTT_DIR
    string
    option env="RTT_ROOT"
    default "../../rt-thread"

config PKGS_DIR
    string
    default "../../packages"

source "$RTT_DIR/Kconfig"
source "$PKGS_DIR/lwar/Kconfig"
source "board/Kconfig"

然后我只要改一下不用环境变量，就可以启动menuconfig。不过原来用环境变量的方法在老版本上一直这么用着的。

mainmenu "RT-Thread Project Configuration"

config BSP_DIR
    string
    option env="BSP_ROOT"
    default "."

config RTT_DIR
    string
    option env="RTT_ROOT"
    default "../../rt-thread"

config PKGS_DIR
    string
    default "../../packages"

source "../../rt-thread/Kconfig"
source "../../packages/lwar/Kconfig"
source "board/Kconfig"
