compile error

Hi Enyu,

what steps did you take to migrate the project?

Chances are you need to add/check/correct your include paths and variables.  Please have a look at the below two wikis and keep us informed whether they help

Hi Lisa,

Stellarisware is installed in the 1st computer in C:/StellarisWare/ and I have imported the example application from C:/StellarisWare/boards/ek-lm3s9d92/blinky to my workspace. CCS automatically copied the files to my workspace and everything ran well.

On the second computer, I did not install Stellarisware. Instead, I copied C:/StellarisWare/ from the 1st computer to the 2nd computer. And then i did the same thing, importing  U:/StellarisWare/boards/ek-lm3s9d92/blinky into the workspace. This time it could not compile.

The version of CCS in the 1st computer is 5.2.1. The version of CCS in the 2nd computer is 5.1.1. 

Hi Enyu,

I suspect your problems could be from the older/mixed versions being used.   If possible I would recommend making sure each PC has a clean fresh installation (no update) of the latest version of CCS (v5.3) and Stellarisware.

At the very least I think pc 2 has the problem due to the old version.

Best REgards,
Lisa

Hi Lisa,

yea i gave up working on pc2.

Right now i have another problem, I have created a new project for LM3S9D92, added "C:/Stellaris" in the includes, and also the "${SW_ROOT}/driverlib/ccs-cm3/Debug/driverlib-cm3.lib" in the library, where SW_ROOT is variable with value = "C:/Stellaris".

I copied the code from the pwmgen example which has the necessary #include "....h"

When it compiles, i get identifiers undefined and warnings of functions declared implicitly. Like as if the includes did not work.

What else could i have missed out here?

Thanks

Enyu

Hi Enyu,

can you please post the exact error/console output.

Best Regards,

Lisa

Hi Enyu,

please check the include option in your compiler options as per this wiki I previously sent.

http://processors.wiki.ti.com/index.php/Include_paths_and_options

The paths to any header and source files you have copied into/created etc in your project should be there.

Best Regards,
Lisa

The following are the settings that I have set and it is exactly the same as from the example code:

Opps the images did not appear on the previous post

Hi Enyu,

a couple things.   You seem very much to be on the correct path but perhaps there are still some items missing.

I only noticed two things at a first look

- there are two path variables pointing to C:/StellarisWare

- you might want to add the path the library in the file search path screen.  It is missing from the bottom portion

Best Regards,
Lisa

Hi Lisa,

I tried making the changes you suggested and I still get the same errors.

Enyu

Hi Enyu,

I suspect you are still missing at least one required library in your project.  GPIO for example ... notice those functions are not defined.

Unfortunately, Stellarisware comes from the Stellaris team and they would much better know what is dependant on what.

I really also would recommend

1 - using the latest version of CCS

2 - starting with an unmodified example to see the dependancies and setup

Best Regards,

Lisa

Hi Enyu,

ok, great, very glad to hear.   Thanks for the update and patience.   I understand that using some of these example suites should be somewhat better documented.

All the best with development.

Best Regards,
Lisa
