kconfig.bat

Recent versions of NuttX support building NuttX from a native Windows CMD.exe shell. But kconfig-frontends is a Linux tool and is not yet available in the pure CMD.exe environment. At this point, there are only a few options for the Windows user (see the top-level README.txt file).

You can, with some effort, run the Cygwin kconfig-mconf tool directly in the CMD.exe shell. In this case, you do not have to modify the .config file, but there are other complexities: You need to temporarily set the Cygwin directories in the PATH variable and then run kconfig-mconf outside of the Make system.

kconfig.bat is a Windows batch file at tools/kconfig.bat that automates these steps. It is used from the top-level NuttX directory like:

tools/kconfig menuconfig

NOTE: There is currently an issue with accessing DOS environment variables from the Cygwin kconfig-mconf running in the CMD.exe shell. The following change to the top-level Kconfig file seems to work around these problems:

config APPSDIR
     string
-   option env="APPSDIR"
+   default "../apps"
