Compiler/CC3220: #define syntax issue

Blake Carpenter

Part Number: CC3220

Tool/software: TI C/C++ Compiler

I have a #define for a string that contains another #define of the firmware version. I have used this method successfully on other compilers, but the TI one does not seem to like it.

// This doesn’t compile I get an error “expected a ;”

#define FIRMWARE VERSION "V0.0.1"

#define MQTT_WILL_MESSAGE "{\"firmware\":\""FIRMWARE_VERSION"\",\"code\":\"WILL_MESSAGE\"}"

// This does compile and I just manually did the text replacement

#define MQTT_WILL_MESSAGE "{\"firmware\":\"""V0.0.1""\",\"code\":\"WILL_MESSAGE\"}"

Any workarounds or ideas?

Is there supposed to be an underscore between FIRMWARE and VERSION in the first macro?

Yes, it is there, just a typo in the post.

I am unable to reproduce the problem. Please submit a test case.

Normally, I ask for a preprocessed source file. That won't work in this case. Preprocessing is where the problem occurs.

Please try to cut down the test case to one source file, and as few header files as possible. Zip all that up and attach to your next post. Indicate what version of the compiler (not CCS) you use. Show all the build options exactly as the compiler sees them.

Thanks and regards,

-George

I figured out the issue. I moved the #define for FIRMWARE_VERSION to a different header file and forgot to update the #include that was referencing it.
