Receiving "Undefined Refernce to ..." Errors

pgvoorhees — Wed, 31 Aug 2016 20:13:51 GMT

Hello NXP forum,

Getting some undefined reference linker errors. I'm receiving undefined reference errors for the daqSpiCh1_MasterState and daqSpiCh1_dmaTcd symbols. Bottom line is that these symbols are declared in daqSpiCh1.h, defined in daqSpiCh1.c. daqSpiCh1.c is being complied (object file is present). But I don't seem to be able to link against those particular symbols.

Linker log is attached also.

I don't mind admitting I'm a little embarrassed that can't seem to define a variable... I appreciate your help and will post more info if it is necessary.
