SK-AM62B-P1: CCS Project: How to properly point to the right time.h

Ayman Ghanem

Part Number: SK-AM62B-P1
Other Parts Discussed in Thread: SYSCONFIG

Hello,

I'm working on porting my project to build in CCS 20.4. There are two files in my project that include a time.h file. The first file should use <time.h>, which should be resolved to "compiler_path/include/c/time.h" as:
#include <time.h>
.....

struct tm loc_time;

The other file is using time.h from "kernel/freertos/FreeRTOS-POSIX/include/FreeRTOS_POSIX/time.h" as:

#include "FreeRTOS_POSIX/time.h"

To fix compiler errors from the second file, I modifed CCS project include options to add:

${MCU_PLUS_SDK_PATH}/source/kernel/freertos/FreeRTOS-POSIX/include
${MCU_PLUS_SDK_PATH}/source/kernel/freertos/FreeRTOS-POSIX/include/FreeRTOS_POSIX
${MCU_PLUS_SDK_PATH}/source/kernel/freertos/FreeRTOS-POSIX/include/FreeRTOS_POSIX/sys

However, when I build the project both files are now using the time.h from FreeRTOS-POSIX and I get compile errors on the first file because "struct tm" isn't defined there. If I comment out those include options, then it is pointing to the compiler's time.h

So, how do I tell the build process to use the compiler/include/c for <time.h> and the FreeRTOS-POSIX for the "FreeRTOS-POSIX/include/time.h"

Thanks.

Hi Ayman,

Please try once after adding compiler's include directory path to the project.

Path - ${CG_TOOL_ROOT}/include/c

Let us know if the above solution works.

Regards,

Tushar

It is already there. This is what I have under include path:

As I mentioned earlier, if I remove the FreeRTOS-POSIX includes, then both files are using time.h from compiler/include/c.

Please provide a sample code to replicate the issue on our EVM.

I'm attaching time_1.c, time_2.c, and the ".cprohject" file that has my include paths. The first file is using <time.h> and the second is using "FreeRTOS-POSIX/time.h". With the include paths defined in .cproject, time_1 fails on "struct tm". If I comment out the FreeRTOS_POSIX includes from the include paths, then time_1 will compile and time_2 will fail.

#include <stdio.h>

bool loc_get_time_1(void)
{
    struct tm currtime;

    DebugP_log("Getting time 1 ....");
    currtime.tm_sec = 0;
    currtime.tm_min = 0;
    currtime.tm_hour = 0;

    return true;
}

    DebugP_log("Getting time 2 ....");
    struct timespec TimeStamp;
    clock_gettime(CLOCK_MONOTONIC, &TimeStamp);
    return true;
}

Use the below code for your time1.c file.

#include <stdio.h>
#include "include/c/time.h"
#include <kernel/dpl/DebugP.h>


uint8_t loc_get_time_1(void)
{
    struct tm currtime;

    DebugP_log("Getting time 1 ....");
    currtime.tm_sec = 0;
    currtime.tm_min = 0;
    currtime.tm_hour = 0;

    return 1;
}

In your application project, add the compiler root directory path ${CG_TOOL_ROOT} instead of ${CG_TOOL_ROOT}/include/c.

After making the above two changes, your project should build without errors.

Please let us know if this works.
