CCS not recognizing GCC predefined macros

Charles Savoie said:

I'm not able to get CCS to recognize the GNU v4.9.1 predefined macros. Any ideas?

From experimenting found that when a new CCS 6 project was created using either the ARM GNU compiler or MSP430 GNU compiler that the CCS symbol indexer wasn't automatically detecting the GNU compiler predefined macros.

To make CCS detect the GNU compiler predefined macros I found that it was necessary to:

- Open the CCS project Properties

- Select "Show advanced settings"

- Select the "Providers" tab on C/C++ General -> Preprocessor Include Paths

- Tick the "CDT GCC Built-in Compiler Settings" provider and un-tick "Use global provider shared between projects"

This causes CCS to run a command to obtain the GNU compiler specs which lists the predefined macros, and now the CCS symbol indexer recognises the predefined macros.

Chester,

Thank you so much for your help. Your answer did get CCS to recognize the GCC predefined symbols, although I am still having trouble with CCS recognizing the mcu symbol.

Compiler flags:

 -mmcu=msp430f449 -I"c:/ti/ccsv6/ccs_base/msp430/include_gcc" -I"c:/ti/ccsv6/tools/compiler/gcc_msp430_4.9.14r1_10/msp430-elf/include" -g -gstrict-dwarf -Wall

Code:

#ifdef __MSP430F449__
//do stuff
#endif

CSS does not recognize.

Any Ideas?

Thank you,

Charlie

Chester,

For some strange reason, adding  -mmcu=${DEVICE} to my command string does not work.

Here's a snapshot of my settings. 

And here are the results.

I've tried every combination under the sun. I appreciate your help.

Thanks,

Chester,

I just rebooted CCS, started a new project with the settings you suggested, and voila! It worked.

Thank you so much!

Now I can get on to the next thing that will frustrate me :-)
