Part Number: TM4C1294NCPDT
Other Parts Discussed in Thread: EK-TM4C1294XL

Tool/software: TI C/C++ Compiler

Hi,

I am using CCS v6 for embedded application development on TI-RTOS for microcontroller TM4C1294NCPDT using C++.

I am using enum class as below:

enum class BitNumbers
{
Bit0,
Bit1,
Bit2,
Bit3,
Bit4,
Bit5,
Bit6,
Bit7
};

Below errors occurred after compilation:

error #111: expected either a definition or a tag name

error #41: expected an identifier

error #66: expected a ";"

warning #12-D: parsing restarts here after previous syntax error

Please help me to resolve these errors.

Thanking you in advance.

Regards,

Harshal

I am unable to reproduce those errors. For the source file which gets those error diagnostics, please submit a test case as described in the article How to Submit a Compiler Test Case.

Thanks and regards,

I am using C++ Example (bigtime) provided in Resource Explorer for TI-RTOS for TivaC for EK-TM4C1294XL without any change.

You must use ARM compiler version 18.1.0.LTS or higher. That is the first version to support strongly typed enum types. To learn how to upgrade the compiler, please see the article Compiler Installation and Selection.

Thanks and regards,

I tried with CCSv7, again it was same issue.

Again tried with CCSv8.1, it compiled successfully.

Thanks for support.

To understand the difference between the version of CCS and the version of the compiler, please see the article Understanding Tool Versioning.

To fix your particular problem, you have to use compiler version 18.1.0.LTS or higher. When you upgraded to CCS 8.1, you happened to upgrade the compiler as well. Please understand that upgrading CCS did not, by itself, fix anything.

Thanks and regards,

Does CCSv6 supports compiler version 18.1.0.LTS ?

If yes, then are any limitations or known issues ?

When we test CCS prior to a release, we use versions of the compiler that are in common use at the time. Since CCSv6 was released well before compiler version 18.1.0.LTS, we did not test them together. That said, it is not unusual for customers to combine older versions of CCS with newer compilers. The farther the releases are apart in time, the more likely the chances of a problem. Most of the time, it tends to work well enough to be practical.

So I recommend you try compiler version 18.1.0.LTS with CCSv6.

Thanks and regards,
