CCS 7.2.0.00013

I have a static bool variable in a file in the project.

I'm trying to declare it as extern bool in two other files.

I am getting linker errors:

undefined          first referenced
symbol                in file
---------          ----------------
bPauseTimerStarted ./REPMTFA_Source/FED_Ope.obj

error #10234-D: unresolved symbols remain
error #10010: errors encountered during linking; "TM4C1294_REPM_TFA_Port.out" not built

>> Compilation failure
makefile:310: recipe for target 'TM4C1294_REPM_TFA_Port.out' failed
gmake[1]: *** [TM4C1294_REPM_TFA_Port.out] Error 1
makefile:306: recipe for target 'all' failed
gmake: *** [all] Error 2

Thanks,

That means this variable is available only within that file. Remove the keyword static, and thus make it global. For more on this topic, please see this general FAQ (not from TI).

Thanks and regards,

Thank you. I didn't actually need for this variable to be static so the problem went away.
