using clock() function time.h in BeyondStudio

[LUIPS]

I am trying to use time.h file clock() function. to get the running time of the program。However,when i build the project,it shows the following errors：

/ba_toolchain/r36379/source/gcc-4.7.4-ba-r36379-build/ba-elf/mcpu_jn51xx_sizeopt/newlib/libc/sys/basim/../../../../../../../gcc-4.7.4-ba-r36379/newlib/libc/sys/basim/glue.c:75: undefined reference to `end'

Could anyone tell me how to solve this problem ?

Hello,

Could you please take a look at the following document for information about BeyondStudio Common Errors?

What Application Note are you using as a base? What modifications did you do?

Also, we highly recommend moving to the JN5189 Wireless MCU for Zigbee® and Thread, as is our focus part for ZigBee/Thread. It is supported by our MCUXpresso IDE and MCUXpresso SDK. There are several SDK examples, like driver examples (GPIO, UART, SPI, I2C), RTOS examples, and Wireless examples (ZigBee and Thread).

Regards,

Ricardo
