CODECOMPOSER: CCS v20.4.1 IDE Indexing Error: Built-in macro __TMS320C2000__ incorrectly identified or pointing to wrong path

Hello,

One thing to try is updating the clangd version. People have reported better functionality with a later version.

See the below post on how to update the version from within CCS:

Thanks

hi,

i have update clangd to 21.1.8 but still failed to solve it.

i'm setting check update in general settings -> extension -> clangd, and reload window for finding newest version.

i have reload window again after update clangd. 

here is the detail infromation about clangd enviroment

original clangd:

C:\ti\ccs2041\ccs\theia\resources\clangd>clangd -version
clangd version 19.1.2 (github.com/.../llvm-project 7ba7d8e2f7b6445b60679da826210cdde29eaf8b)
Features: windows+grpc
Platform: x86_64-pc-windows-msvc

update clangd:

Ok, thanks for trying. This may be a known limitation. If you explicitly add "__TMS320C2000__" to the predefined symbols list, does it then get picked up?
