"stdbool.h" is missing. Where is it?

[Tsan-Ming]

I tried to build the example project "ble_app_uart" bundled with nRF5 SDK (nRF5_SDK_11.0.0_89a8197) within the MDK-Lite V5.18K. It failed and I got the following messages:

*** Using Compiler 'V5.06 update 1 (build 61)', folder: 'C:\Keil_v5\ARM\ARMCC\Bin' Build target 'nrf52832_xxaa_s132' compiling main.c... ............\components\ble\common\ble_advdata.h(26): error: #5: cannot open source input file "stdbool.h": No such file or directory #include <stdbool.h> ......\main.c: 0 warnings, 1 error compiling bsp.c... ..........\bsp\bsp.h(32): error: #5: cannot open source input file "stdbool.h": No such file or directory

It seemed that the header file "stdbool.h" is missing. Which pack should I install from the Pack Installer? I had tried some other examples and same things happened. How to solve this problem? Thanks for any suggestion.

it should come with KEIL intallation, if it is missing then something went wrong. It should be located in KEIL_DIR\ARM\ARMCC\include
