Tool/software: Code Composer Studio
I added a version string to my code using the $current_date compiler variable but it gets compiled out of my code.
I set a string with this line in my code:
char versiont[20] = TIMESTAMP;
TIMESTAMP is defined in the predefined name section of CCS with this definition:
TIMESTAMP="\""${current_date}"\""
However, version is always compiled out unless I use it in my code. I worked around this by setting some other variable (that gets overwritten) to one of the elements of version but this seems like bad coding. I want this string for checking in CCS but currently I do not need to use it in the execution of my code. I tried the following:
static volatile char versiont[20] = TIMESTAMP;
volatile char versiont[20] = TIMESTAMP;
char version[20] __attribute__ ((used))= TIMESTAMP;
and the "full Monty":
static volatile char versiont[20] __attribute__ ((used)) = TIMESTAMP;
but none of these worked.
I also tried the -Retain linker option but got an error because I use COEF instead of EFL for my code output. (Should I be using ELF for some reason?? Will changing to ELF cause any other issues?)
Does anyone know how to make this variable survive linking without being used in the code?
