unresolved external

Recommended Posts

Hi,

i'm getting "error LNK2019: unresolved external symbol " for method well defined (as fat as i can tell..). the only difference from other blocks is the template of the module (so what??). the outline of the code is supplemented. hope someone can shade some light...

Hi Philipp,

thank you for promptly responding. as it is, i read this web page top to bottom, i still could not figure out the problem.

i comment out the declaration SC_METHOD(thread0) and the compiler succeeded .. so the declaration is the problem? how can i distinguish between METHOD, THREAD and CTHREAD without this macro.. obviously, i have no clue what is going on here..
