Error Listing symbols

[YASH]

Hi All,

I am working on BLE+SD card Library, s132. Although i am getting certain errors which i am unable to counter.:-

*** Using Compiler 'V5.06 update 4 (build 422)', folder: 'C:\Keil_v5\ARM\ARMCC\Bin'

I know that this happens because my compiler is unable to to identify the symbols although the particular header files are present.

One more thing, my app_sdcard. c source file is not including its header files, it is only including sdk_config.h

Why is this happening? How should i counter this problem? The header files are added to path.

Thanks in advance.

Best Regards.

I got the answer for this, the app_sdcard.c source file has a code snippet which says:-

#include "sdk_config.h"
#if APP_SDCARD_ENABLED

#include "app_sdcard.h"
#include "nrf_gpio.h"
#include "nrf_drv_spi.h"
#include "app_error.h"
#include "nrf_assert.h"

#include "nrf_pt.h"

that means if APP_SDCARD_ENABLED is 1, then only it will include other header files. So i had to set it as 1 in sdk_config.h file.
