MSPM0L1306: Semantic errors referencing C++ std lib symbols, but project builds successfully

Hello Gordon,

I think maybe you can refer to the method mentioned in this E2E post.

(+) CCS: How to create a C++ project? Is there a template? - Code Composer Studio forum - Code Composer Studio︎ - TI E2E support forums

And M0 project also has the configuration of language, you can try to do some modification and try to check if modifying this configuration can help you resolve this issue.

And I think that you need to check that which C++ version will be supported by which GCC version.

And about why the GCC compiler doesn't automatically include that dir for C++ source file, I think you can contact with the company who develop and support the GCC compiler.

Hi Janz,

I basically did what that thread described. I renamed main.c to main.cpp. GCC compiles it successfully with no errors.

However, CCS itself shows these "semantic errors" in the Problems window. I believe that CCS does not know that the compiler automatically includes this directory with the C++ headers. I don't know what the Right Way is in CCS to tell it how to find those C++ headers.

Hello Gordon,

I will give this E2E post to our SDTO team, and they will help you on this issue.

Gordon,

Header file search paths can be specified here:

I added the folder containing the C++ headers to that list but I still see errors in CCS for these symbols even though I can Ctrl-Click navigate to them and GCC builds the project without error.

Thanks, I will take a look at CCS Theia. Are the project file formats compatible?

Yes projects are compatible.  You can just import existing projects straight into CCS Theia.  Same for examples from the SDK.

We are still doing service releases for CCS Eclipse but the plan is by the end of the year to have completely switched to Theia.

CCS Theia handles it much better. Thanks!

Does CCS Theia have feature parity with the original CCS?

It varies depending on the device being used.  For example there are some multicore debugging features missing but those don't impact MSPM0.

For MSPM0 the key features should all be there.  However it is a different environment.  It uses the Theia application framework which provides an experience much more like VS Code.

Is there anything like the AppCenter for installing tools like GCC?

Resource Explorer is present.  If an SDK has GCC specified as a dependency then it will allow you to download the required version. Updates to installed GCC versions are also available this way, i.e. if you had GCC 9.2.1 and we packaged an updated 9.2 then you would see it when checking for updates.
