CCS/MSP-EXP432P401R: Bitset headers not resolving in CCS

Hi Roger,

Is your source file that is containing bitset ending with .cpp?

I compiled this quick minimal example and it compiled fine but only after I used the .cpp extension.

#include "msp.h"

/* Example 01: Bitset
Explains the usage std::bitset
*/
 

#include <bitset>

 
using namespace std;
 
void main()
{
	WDT_A->CTL = WDT_A_CTL_PW | WDT_A_CTL_HOLD;		// stop watchdog timer
    //Constuct 01: 8 bits initialized to zero
    bitset<8> bitset1;
 }

I tried the above example by creating a new CCS project and then copied the code above into that main() and renamed to cpp. I get all the same errors as before - this is a small snippet. The errors seem to be on all the header files bitset is 'including'. Is there a option or ? I need to set in the project properties or do I need to open a new project in some other way.

Hey Roger,

Try importing this project via CCS Import -> C/C++ -> CCS Projects. I see the issue you are having but didn't experience this problem when using CCS Cloud. So I downloaded my test project from CCS Cloud and imported into CCS and it works fine. So I would have to dig in to understand what the difference is but hopefully by using this project you will be unblocked for now.

Something quite odd is happening.  I copied these steps ...

It builds fine for me.  

Please package up your problem project as described in the article Project Sharing, then attach the resulting zip file to your next post.

Thanks and regards,

Hi George,

Attached is a sample project. Basically I created this via CCS using File -> Project -> CCS Project. Select target to MSP432P4111. I use the above code that I showed and change main.c to main.cpp. What is weird is that using the CCS Cloud project works but a project created from CCS isn't working.

Thank you for submitting your project.   When I build it, I only see these two compiler diagnostics ...

"../main.cpp", line 10: error #20: identifier "bitset" is undefined
"../main.cpp", line 10: error #20: identifier "bitset1" is undefined

That is because line 10 is ...

    bitset<8> bitset1;

The type bitset is not in the global namespace, but the std namespace.  There is no using directive which brings in the std namespace.  When I change that line to ...

    std::bitset<8> bitset1;

... it builds clean.  For a discussion of this solution compared to a using directive, please see this FAQ (not from TI).

Thanks and regards,

-George

Hi George, what is even more wierd is that at my office computer I deleted and reinstalled CCS with only the EXP432 family selected - no SDKs. I then imported your project and compiled - it compiled without error.
Last night I did the same thing with my computer at home (which is the one I am creating the code on), uninstalled, reinstalled with only 432 family - imported the file and got the following errors:

both computers running WIN 10 latest updates.
The only difference I can figure is that the work computer has one drive: 'C' and my home computer has many drives with CCS being installed on my development drive with no other modifications to the install parameters.

I am perplexed!

... looks like the exact same error I discuss in my previous post.  If the fix in that post does not address this situation, then I'm stumped.  And the only way forward is for you to somehow send us a test case which allows us to experience the same problem for the same reason.

Thanks and regards,

Did you resolve your problem?  If so, I'd appreciate hearing how you resolved it.

Thanks and regards,
