TMS570LC4357: Unble to compile basic DCAN_TX code.

Part Number: TMS570LC4357

I made a simple CAN_TX code where I am transmitting "HERCULES" through CAN4 through message box 1, but I am unable to compile my code and having the following errors:

    Also If required I have attached my project file:0830.DCAN_TX.7z

    Yash,

    That error message is indicative of a syntax error. The actual 'mistake' might be in the line(s) preceding the one where missing ';' is reported.

    I don't 'see' the error looking at the code you pasted. I'd be looking for a missing ';' obviously but also some mistake in mismatched {} or () or ',' an extra token in some statement .. that sort of problem.

    You'll find this quickest using the help in the IDE... pay attention to syntax highlighting.

    You can also try commenting out lines of code and recompiling till the error disappears. Then start uncommenting till it comes back. Sometimes this helps if you are 'stuck' and can't just 'see' the error any other way and you can do as sort of binary search this way by commenting/uncommenting smaller sections of code until you home in on the bad lines.

    Hello Anthony,

    I commented the entire code, essentially making the code equivalent to 

    int main (void){

}

    and still got the same errors mentioned above>

    NOTE: The error is directing me to _lock.h file which is a system library which is available in the directory: C:\ti\ccsv6\tools\compiler\arp32_1.0.8\include

    I included the directory in my compiler include options in the first place because if not included compiler showed an error stating it could not find stdint.h

    I tried making few changes to the _lock.h but couldn't solve anything. I think that there is a problem not in the syntax of the library but the way it is being compiled.

    I request you to try compiling the project I had included above (note: please include the respective directory for stdint.h and stdbool.h in the compiler include options)

    The error messages are coming from the C:\ti\ccsv6\tools\compiler\arp32_1.0.8\include\_lock.h file which is part of the run time library for the arp32 compiler used for the EVE (Embedded Vision Engine) devices, whereas for a TMS570LC4357 device the include files for the ARM compiler should be used.

    Looking at the project properties for DCAN_TX project shows that in the Include path "C:\ti\ccsv6\tools\compiler\arp32_1.0.8\include" has been specified. Not sure how that happened, but try replacing with the standard "${CG_TOOL_ROOT}/include" include path so that the ARM compiler include directory is used.

    With that change I was able to get the project to compile.

    Thank you, Chester,
    That solved my problem.
