[AVR club] AVR GCC - Commands/Marco List? - Rakesh Kumar - Jun 16 6:03:34 2007
Hello all,
I am looking for a list of Commands/Macros which are available in AVR GCC
documented at one place. I looked around at the google but couldn't find
anything significant. Do you know any web-links or have anything, please do
send it to the group or upload in the files section.

If you execute the following commands:
touch empty.c
avr-gcc -E -Wp,-dD,-dM empty.c
this will print out a list of all of the builtin macros along with
their values. If you replace empty.c with a real source file, then it
will print out all of the macros in effect by the end of the source
file.
Note that "-Wp,-dD,-dM" is one option with no spaces after any of the commas.

Hey Dave,
Thanks a lot for the promising and prompt reply.
However, I don't really get the context of where to execute these commands.
I use AVR-GCC (WinAVR) in the AVR Studio on my Windows XP machine. Can you
guide me a with little background on these commands and if possible, how
execute them in my environment.

You would execute them from a command line prompt. Under XP, choose
Start->Run and type in cmd
That should bring up a command prompt.
Then do
C:
cd \winAVR\bin
touch empty.c
avr-gcc -E -Wp,-dD,-dM empty.c > foo.txt
The output from mine looks like (running" avr-gcc --version" reports 3.4.)
