LPC55S69 lib "short enum wchar" question

[scarletlee]

Hi,

I have 2 questions.

First, I want to know these lib mean as below ( bold font is my understanding...) :

./devices/LPC55S69/arm/
keil_lib_power_cm33_core1_disable_short_enum_wchar.lib
//a disable short enum wchar lib for CPU1

keil_lib_power_cm33_core0_s.lib
//a security lib for CPU0

keil_lib_power_cm33_core0.lib
//a common lib for CPU0

keil_lib_power_cm33_core0_s_disable_short_enum_wchar.lib
//a disable short enum wchar with security lib for CPU0

keil_lib_power_cm33_core0_disable_short_enum_wchar.lib
//a disable short enum wchar lib for CPU0

keil_lib_power_cm33_core1.lib
//a common lib for CPU1

Second, I always get compiler failure when I uncheck "short enums/wchar". ( as attached file)

How can I fix this issue?

Thanks.

Hello scarletlee,

1) There isn't a doc detail describe these libs, almost the meaning of name. 

2) About the second question,  the application and lib must keep the same compiler settings. if the settings don't match, compiler will produce the mismatch error.  Have  a look at the below thread:
