Part Number: LAUNCHXL-CC1352R1
Tool/software:
I am trying to convert the Project Zero BLE example from the SimpleLink CC13x2 SDK into a static library so I can reuse it across multiple projects. However, I am facing compilation errors after removing hardware-specific files like ble_user_config.c.
Here’s what I have done so far:
-
Removed OAD (Over-the-Air Download) support since I don’t need it.
-
Excluded
ble_user_config.cfrom the static library because it contains hardware-dependent configurations that should remain in the main project. -
Defined necessary preprocessor symbols from the example project in the library.
Issues & Errors
After compiling, I encountered the following errors:
shell
1965 cannot open source file "xdc/std.h"
20 identifier "coexUseCaseConfig_t" is undefined
20 identifier "cteAntProp_t" is undefined
20 identifier "ECCParams_CurveParams" is undefined
20 identifier "rfOpCmd_cntBranch_t" is undefined
20 identifier "rfOpCmd_runImmedCmd_t" is undefined
20 identifier "rtosApiTblPtr_t" is undefined
These errors seem to be related to missing dependencies from ble_user_config.c.
Questions:
-
What is the recommended way to handle
ble_user_config.cwhen converting a BLE project into a static library?-
Should I manually define missing structs (
coexUseCaseConfig_t,cteAntProp_t, etc.) inmain.c? -
Or should I include a minimal version of
ble_user_config.cinside the library?
-
-
How can I properly handle dependencies on
xdc/std.hand TI-RTOS headers when building a static library?-
The library does not seem to recognize
xdc/std.heven though I have included TI-RTOS paths.
-
-
Are there any best practices for structuring a BLE project as a static library in Code Composer Studio?
Any insights would be greatly appreciated!
