Tool/software: Code Composer Studio
I am trying to create a variable loaded with the contents of windows system variable %computername%.
The previous thread suggests inserting a flag -DHOSTNAME=%COMPUTERNAME% into the project properties - ARM Compiler.
That doesn't seem to work:
-D__HOSTNAME__=%COMPUTERNAME%
expands as a command-line string:
--define=__HOSTNAME__=%COMPUTERNAME%
and when referenced as
strcpy(p_txBuffer,__HOSTNAME__);
I am getting error: "../ipb_dbg_uart.c", line 1359: error #29: expected an expression.
During debugging I tried defining the string without using the system environment variable - just to try what may be wrong.
both --define=HOSTNAME=MY_MACHINE or --define=HOSTNAME="MY_MACHINE" yield error #20: identifier "MY_MACHINE" is undefined.
Clearly - the double quotes are "eaten away" in the process.
After lengthy experimenting I got my project build when I escaped the double quote marks:
--define=HOSTNAME=\"MY_MACHINE\"
However, --define=__HOSTNAME__=\"%COMPUTERNAME%\" returns the string "%COMPUTERNAME%" without the substitution for the environment variable.
What am I missing here?
Thanks! Martin
